Chapter 4: Function Description

This section presents the network concepts referred to in the switch function description.

4.1 System Setting

System setting contains the following topics: displaying and configuring the switch information, upgrading firmware, backing up and loading configuration, rebooting and soft-resetting, configuring username and password.

4.1.1 System Information

The system information contains a hardware version, software version, system description, system name, system location, contact information, and run time.

4.1.2 File Transfer

The TL-SG2216WEB/TL-SG2224WEB Web-Smart Switch Family is equipped with a configuration backup function, configuration loading, and system upgrading.

The configuration file and executive file are transferred using the TFTP protocol. TFTP (Trivial File Transfer Protocol) is dedicated to transferring files between two network stations. It is based on the UDP protocol.

4.1.3 Reboot & Reset

The "Reset" indicates "Soft-reset" here. Soft-resetting restores the switch configuration to default except for the switch IP address.

4.1.4 User

The username and password can be modified in order to exclude illegal users.

4.2 Port Setting

4.2.1 Port Parameter

4.2.1.1 Duplex Mode

Ports have duplex modes, 10M HD, 10M FD, 100M HD, 100M FD and 1000M FD.

The First part indicates the transmission rate and the second part indicates the duplex mode.

HD: half-duplex, the port supports transmission between the device and the client in only one direction at a time. FD: full-duplex, the port supports transmission between the device and its link partner in both directions simultaneously.

Switch support auto negotiation, it's a protocol between two link partners that enables a port to advertise its transmission rate and duplex mode to its partner.

4.2.1.2 Flow Control

Flow control enables lower speed devices to communicate with higher speed devices. This is implemented by the higher speed device refraining from sending packets.

4.2.1.3 Port Security

If the port security is enabled, it will not learn new MAC address and only

transmit the frames from the MAC address list in the port's static MAC address table.

4.2.2 Port Statistic and Port Status

Port Statistic calculates the statistics of each port, such as how many frames, error frames, broadcast frames it has received, and so on.

Port Status indicates whether the port is linkup, linkdown or disabled, what speed and duplex mode it is working on, and whether flow control is enabled or disabled.

4.2.3 Storm Control

Storm control limits the amount of multicast, broadcast and UL (addresses that have not been learned) frames accepted and forwarded by the device. When Layer 2 frames are forwarded, broadcast, multicast and UL frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes on all ports.

A Storm is a result of an excessive amount of these frames simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to time out. Storm control is enabled for all ports by defining the packet type and the rate at which the packets are transmitted. The system measures the incoming defined frame rates on each port, and discards the frames when the rate exceeds a user-defined rate.

4.2.4 Port Description

Use a description word to indicate the port.

4.3 Network Setting

The network module provides setting switch IP address, dynamic binding and aging time, configuring static MAC address and filtering MAC address, displaying dynamic bound address and ping functions.

4.3.1 Switch IP Address

An IP address is indispensable for a switch to be accessed. The TL-SG2216WEB/TL-SG2224WEB Web-Smart Switch Family provides the configuration interface of IP address, netmask and default gateway.

DHCP (Dynamic Host Configuration Protocol) is dedicated for the DHCP client to obtain IP configuration information from the DHCP server. Two types of information are included in IP configuration information. One type is specific configuration information; another is IP address parameter. DHCP is based on client-server mode. The network station that offers the IP configuration information is called DHCP server.

Make sure that a DHCP server is correctly connected to the network, enable the DHCP client function of the switch, then the switch will automatically obtain IP address, netmask and default gateway from the DHCP server.

If more than one DHCP servers are available in the network, the switch will choose one according to a specific algorithm.

Notice:

If no DHCP server is present in the network, the DHCP client fails to get IP configuration information, and the switch then restores the IP parameters to default in several minutes to ensure a valid IP address being equipped.

4.3.2 Aging Time and Dynamic Address Table

A dynamic MAC address table is maintained inside the switch. A MAC address is the physical address of a network device; it is six-bytes long and should be unique in a subnet. A network device can be identified by its MAC address.

A dynamic address table entry contains two items: MAC address and its corresponding switch port. The dynamic address table is volatile. The dynamic address entry begins to age once it is added; it will be purged if it isn't renewed in a specified time length, which is defined as aging time.

The aging time ranges from 0 to 630 seconds for this switch family.

The default value is 300 seconds. Dynamic address table entry won't age if 0 is set. The aging time precision is 15 seconds.

4.3.3 Static MAC Address Table

A static MAC address table entry contains a MAC address and its corresponding switch port. All the packets taking that MAC address as their destination will be forwarded to the corresponding switch port.

The static MAC address won't age, which differs from the dynamic MAC address. The static MAC address table entry is always valid before it is deleted.

Suppose an entry, whose MAC address is 000AEB000001 and corresponding port number is 1, is added to the static MAC address table. All the packets routing to the address of 000AEB000001 egress for the switch port 1. This static entry obliges the device of 000AEB000001 to be connected to port 1; otherwise, that device cannot be accessed. Static MAC addresses are free of

MAC learning, which enhances the efficiency of packets forwarding. The MAC addresses already configured in static MAC address table cannot be added to filtering MAC address table.

The static MAC address table capacity of different type of switches may be different. Appendix C lists the difference.

4.3.4 Filtering MAC Address Table

A filtering MAC address excludes a device from being accessed through the switch. All the packets taking the filtering MAC address as their destination will be discarded. The filtering MAC address is applicable to all the switch ports. The configured filtering MAC address can neither be added to static MAC address table, nor be bound by switch ports.

4.3.5 Dynamic Binding

A switch port in dynamic binding state can bind a specified number of MAC addresses. Once the specified number is reached, the port transfers into secure state automatically and stops binding MAC addresses. The bound MAC addresses won't age; they can be removed by disabling the dynamic binding or rebooting the switch.

The function of dynamic binding causes the switch port to acknowledge the devices connecting to it after startup, and stores the connections (through binding MAC addresses) in static state. This enhances the efficiency of packet forwarding and limits the number of connecting devices on the switch port. Reboot the switch after configuring the dynamic binding function. The switch will acknowledge and bind the latest connecting devices. If the switch is managed through remote connection, please add the MAC address of the

management computer or that of the default gateway to the static MAC address table; otherwise, the management channel may be broken down.

4.3.6 Ping

The ping function is used to test the connectivity of the link between the switch and the destination.

4.4 VLAN Setting

VLANs are logical subgroups within a Local Area Network (LAN) that combine user stations and network devices into a single unit, regardless of the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups.

VLANs use software to reduce the time it takes for network changes, additions, and moves to be implemented.

VLANs can be created per unit, per device, or through any other logical connection combination, since they are software-based and not defined by physical attributes. VLANs function at Layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router working at a protocol level is required to allow traffic flow between VLANs. Layer 3 routers identify segments and coordinate with VLANs. VLANs are Broadcast and Multicast domains. Broadcast and Multicast traffic is transmitted only in the VLAN in which the traffic is generated.

4.4.1 VLAN Mode

There are 3 types of VLAN modes supported in the switch:

1) Port VLAN

VLANs are divided based on ports.

2) IEEE802.1Q Tag VLAN

The IEEE802.1Q protocol defines a new format of the frame; it adds a tag header in the original Ethernet frame, as follows:

Figure 4-1. IEEE802.1Q frame

IEEE802.1Q Tag VLAN is divided by VLAN ID (VID). On receiving a frame, the switch checks the VID in the tag header of the frame to decide which VLAN it belongs to. If the receiving frame doesn't contain the tag header, the switch will assign a tag to the frame, using the PVID of the port as its VID.

3) MTU VLAN

MTU VLAN (Multi-Tenant Unit VLAN) defines an uplink port. The uplink port will build up several VLANs with each of the other ports. Each VLAN contains two ports: the uplink port and one of the other ports in the switch. So the uplink port can communicate with any other ports, but other ports can't communicate with each other.

4.5 Port Trunking

Trunking refers to Link Aggregation. It optimizes port usage by linking a group of ports together to form a single trunk (aggregated groups). The bandwidth of the Trunk is the sum of bandwidth of its member ports.

There are some rules on using Trunk:

1) Before setting the Trunk, its member ports should be divided to the same VLAN, and have the same PVID and drop the untagged frame rule. Change of the Trunk setting will not affect the VLAN setting. Trunks cannot be set if the switch is in MTU VLAN mode. 2) The Trunk member ports cannot enable port security and cannot be set as mirror or mirrored port. 3) All of the Trunk member ports should be connected correctly; otherwise some ports will not be able to work.

4.6 Priority Setting

The priority mode of the switch can be set to "Disable", "Port-Based" or "IEEE802.1p".

4.6.1 Priority Mode

Three priority modes (disable, port-based and IEEE802.1p) are provided for this switch family.

The priority rule can be set to "Weighted" or "Fixed". When the priority rule is configured as "weighted", a 1,2,4,8 weighting is applied to forward packets. When "fixed" is selected, all packets with top priority egress for a switch port until that priority's queue is empty, then the packets with next lower priority.

4.6.2 Port-Based Priority

Four priority classes (lowest, lower, higher and highest) are available for a switch port in port-based priority mode. The priority class of the port is applied to all packets entering from the port.

4.6.3 Port Default Priority

If IEEE802.1p priority mode is configured, when a switch port receives an untagged frame (a frame without priority tag), the port's default priority tag will be inserted into the frame before any other process.

4.6.4 802.1p Priority

In IEEE802.1p priority mode, all packets are classified into four priority classes (lowest, lower, higher and highest) according to the embedded priority tag. If an untagged frame is received, the default priority tag of the port will be attached.

4.7 Port Mirroring

Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. Port mirroring enables switch performance monitoring.

Network administrators can configure port mirroring by selecting a specific port from which to copy all packets, and other ports to which the packets copied.

4.8 Virtual Cable Test

The virtual cable test feature uses Time Domain Reflectometry (TDR) to test

the quality of the cables connected to the port. Some of the possible problems than can be diagnosed include opens, shorts, cable impedance mismatch, bad connectors, termination mismatch, and bad magnetics. It can also test the distance to the problem location, with the precision of ±1 meter.

Configuration Backup: Means backing up the current configuration of the switch to TFTP server. Configuration Loading: Means downloading the configuration from TFTP server to the switch and update it.

Notice:

1) Please make sure the target file exists on TFTP server before downloading. 2) Please make sure the TFTP server is in operation. 3) Breaks should be avoided in file transfer; otherwise, the switch may be damaged.

This page is shown below.

Figure 5-15 Reboot & Reset

A prompt will display if a button is pressed. For example, if the button "Soft-reset" is pressed, a message box will be activated as shown in figure 5-16.

Figure 5-16 Message Box

5.3.1.4 User

This page provides the interface for configuring username and password.

Figure 5-17 User Configuration

You are kindly suggested to retype the new password in the "Confirm new password" box instead of copying it, in order to avoid mistakes.

Notice:

1) Only letters, numbers, and punctuation can be entered into the username and password fields; other characters are considered illegal. The length of the username and password ranges from 1 to 16 characters. 2) The initial username and password are supervisor/supervisor.

5.3.2 Port Setting

5.3.2.1 Port Parameter

This page contains the following fields:

Figure 5-18 Port Parameter

Port Status: Indicates whether the port is operational or non-operational. "Enable" indicates that the port is operational, and "Disable" indicates the port is non-operational. If a port is unused for a long time, it can be set to non-operational to reduce energy costs.

Notice:

1) You cannot manage the switch via a port that is non-operational; please set the value of the management port to "Enable". 2) SFP ports are combo ports sharing a connection with a Gigabit port. In TL-SG2216WEB, SFP1 and port 15 compose a combo port, SFP2 and port 16 compose a combo port; in TL-SG2224WEB, SFP1 and port 23 compose a combo port, SFP2 and port 24 compose a combo port. For a

combo port, only one operation type can be active at a time. If both ports are connected at the same time, the SFP port has priority to be active. The combo port uses the same configuration. For example, in TL-SG2216WEB, if port 15 is active and the Port Status parameter is set to "Disable", when SFP1 is active, its Port Status parameter will also be "Disable".

Port Security: "Enable" indicates that the port will not learn new MAC addresses and will only transmit frames from the MAC addresses it has already learned. "Disable" indicates that it will learn new MAC addresses.

Notice:

If you have not set static MAC addresses, you cannot set all ports' security to enabled, as this would prevent you from managing the switch.

Flow Control: Indicates whether flow control is enabled or disabled.

Notice:

If the port is working at half duplex, the settings of flow control are divided into several groups (each group includes 6 ports), for example, port 1 to 6 are assigned to group 1. The ports of the same group share the same flow control settings, so when you modify the setting of one port, those of the other ports are changed correspondingly.

Duplex Mode: Possible field values are Auto, 10M HD, 10M FD, 100M HD, 100M FD and 1000M FD. "HD" stands for half-duplex and "FD" stands for full-duplex. "Auto" means auto negotiation.

Notice:

Though the SFP module supports hot-plugging, the configuration of Duplex Mode cannot change automatically. After switching between UTP, 100M SFP and 1000M SFP on the combo port, please modify its Duplex Mode manually or re-electrify the switch to make sure the configuration is correct. The 100M SFP should be set to "100M FD" and the 1000M SFP should be set to "AUTO" or "1000M FD".

Further explanation:

1) By operating on fields in the All Ports line expediently, you can set the values of all ports in the corresponding field. Some other setting pages offer the same function. 2) Parameters of Trunk member ports are configured with default values (see the Appendix B table) and cannot be configured here (see port 5 and 6 in the figure for example).

5.3.2.2 Port Statistic

This page displays the port statistic. It contains the following entries:

Figure 5-19 Port Statistic

Tx Collisions: The number of collision events seen by the MAC. This counter is applicable in half-duplex only. Tx Ucast: The number of frames sent that have a unicast destination MAC address. Tx Mcast: The number of frames sent that have a multicast destination MAC address. Tx Bcast: The number of frames sent that have a broadcast destination MAC address. Rx (G Pkts): The number of good frames received. Rx Ucast: The number of frames received that have a unicast destination MAC address. Rx Mcast: The number of frames received that have a multicast destination MAC address. Rx Bcast: The number of frames received that have a broadcast destination MAC address. Rx (B Bytes): The sum of bytes of frames received with an invalid length. The frames with the length more than 1522 octets are counted as 1522 octets ones. Rx UnderSz: Total frames received with a length of less than 64 octets but with a valid FCS. Rx OverSize: Total frames received with a length of more than max size octets but with a valid FCS. Rx Jabber: Total frames received with a length of more than max size octets but with an invalid FCS. ➢ 64 B: Total frames received and transmitted with a length of exactly 64 octets, including those with errors. ➢ 65 to 127 B: Total frames received and transmitted with a length of

between 65 and 127 octets inclusive, including those with errors.

128 to 255 B: Total frames received and transmitted with a length of between 128 and 255 octets inclusive, including those with errors. 256 to 511 B: Total frames received and transmitted with a length of between 256 and 511 octets inclusive, including those with errors. 512 to 1023 B: Total frames received and transmitted with a length of between 512 and 1023 octets inclusive, including those with errors. RX Bytes: The sum of bytes of frames received, not including those with errors.

Notice:

Each statistic counter has a maximum numerical value of about 1.8e+19. If this value is exceeded, the counter will reset to zero. You can also click the "Reset" button to reset all statistic counters to zero.

5.3.2.4 Storm Control

This page contains the following fields:

Figure 5-21 Storm Control

➢ Broadcast Control: Enable or disable broadcast control to limit broadcast frames. Ports belonging to the same Trunk should have the same value. Multicast Control: Enable or disable multicast control to limit multicast frames. Enabling multicast control will also enable broadcast control. All ports share the same setting. UL Control: Enable or disable UL control to limit UL packets. Enabling UL control will also enable broadcast control and multicast control. All ports share the same setting. Limit Rate: Indicates the maximum rate (frames per second) at which the controlled packets configured above are forwarded. For UL control, the unit is kilo frames per second, and the statistic is the sum of all ports. All ports share the same setting.

5.3.2.5 Port Description

This page configures the description to indicate the ports.

Input description words in the Description field for each port. Note that each field can hold at most 15 letters or numbers.

Figure 5-22 Port Description

5.3.3 Network Setting

This page contains the following topics: switch IP address, static MAC address, filtering MAC address, dynamic binding, bound MAC address, aging time, and ping.

5.3.3.1 Switch IP Address

This page is shown below:

Figure 5-23 Switch IP Address

MAC Address: Is fixed into the switch during the manufacturing process; it is unique and unchangeable.

DHCP Client: Indicates whether the DHCP function is enabled. If DHCP client is enabled, the switch will obtain the IP address, netmask, and default gateway from the DHCP server automatically; otherwise, these three items should be configured manually. IP Address: Is necessary for switch management. The configuration of the switch IP address must be compliant with the subnet layout. Default Gateway: Serves as the default destination when a packet whose destination IP address is not within the switch's subnet is to be forwarded.

Notice:

1) When DHCP client is enabled, the IP parameters are obtained automatically from the DHCP server, so the "IP Address", "Netmask", and "Default Gateway" fields are disabled. These parameters can be queried on the DHCP server. 2) The initial state of the DHCP client is disabled and the initial IP address is 192.168.0.1.

5.3.3.2 Static MAC Address

This page provides the function of adding, searching a static MAC address, and changing the entry state, as shown in Figure 5-24.

Figure 5-24 Static MAC address

A MAC address and its corresponding switch port should be provided when adding a static MAC address entry.

➢ Search: Input the MAC address in the "MAC Address" field and click the "Search" button. If that MAC address exists, the following page will display:

Figure 5-25 A Successful Search

Index: Stands for entry index of the MAC address in the table. Port: Stands for the switch port number. State: Indicates the entry in enabled state or disabled state. Operation: Provides the function of enabling, disabling or deleting an entry. Return: Return to the "Static MAC Address" page.

A search can also be executed in this page.

If the static MAC address isn't found in searching, then the following page will display:

Figure 5-26 A Failed Search

Add: Input the MAC address in the "MAC Address" field and select a port number in "Corresponding Port" combo box, click the "Add" button, that MAC addresses may be added to the static MAC address table if the following conditions are met:

1) That MAC address doesn't exist in static MAC address; 2) That MAC address doesn't exist in filtering MAC address; 3) There is enough space in static MAC address table (the capacity of the static MAC address table is shown in "Appendix C").

The static MAC address table is divided into several pages. At most 10 entries can be held in on page. The buttons "First", "Previous" and "Next" can be used to browse the whole table.

Notice:

1) The capacity of the static MAC address is showed in "Appendix C". 2) If an incorrect port number is selected when adding an entry, or the port number is modified unexpectedly later, then the entries must be renewed; otherwise, the packets cannot be forwarded correctly. 3) If a device, whose MAC address is added to static MAC address table, is connected to a wrong switch port (not the port configured in static MAC address entry), all the packets routing to the device cannot reach the device. 4) A MAC address cannot be added to static MAC address table and filtering MAC address table simultaneously.

5.3.3.3 Filtering MAC Address

All the packets taking the filtering MAC address as their destination are

discarded by the switch no matter which port they enter from.

This page provides the function of adding, searching a filtering MAC address and changing the entry state. The filtering MAC address entry is applicable to all switch ports. The operating instruments, which are similar to "Static MAC Address", are omitted here.

Figure 5-27 Filtering MAC Address

Index: Indicates the entry index of filtering MAC address table. MAC Address: Indicates the filtering MAC address to be configured or to be searched. State: Indicates the entry in enabled state or disabled state.

Notice:

The capacity of filtering MAC address table is showed in "Appendix C".

5.3.3.4 Dynamic Binding

This page provides the function of enabling or disabling dynamic binding.

If dynamic binding is disabled, the switch port learns MAC address unlimitedly (at most 8000 entries can be learned actually).

A switch port with dynamic binding enabled can bind a specified number of

MAC addresses. The MAC addresses bound by the switch port are always valid and won't age. If the specified number is reached, the port stops binding and transfers into secure state.

The bound MAC addresses can be queried in the "Bound MAC Address" page.

If the dynamic binding is disabled or the switch restarts, the bound MAC address entries are cleared.

There are 5 items in this page:

Figure 5-28 Dynamic Binding

➢ Port: Indicates switch port number.

Binding: Three options are available. A further explanation is stated below. Number of MAC Address to Bind: Indicates the max number of MAC addresses that one switch port can bind. ➢ Number of Bound MAC Address: Indicates the number of MAC addresses that already bind to a switch port. State: Indicates the switch port state that may be binding, free port, secure port, unplugged or "--". A further explanation is stated below.

Further explanation

Options of dynamic binding:

1) Disable: Cause this port to learn MAC address freely. 2) Enable: Cause the port to bind MAC addresses until the specified number is reached. 3) --: This option is available only if the port is in secure state, when this option is selected, the port state keeps unchanged.

Port states:

1) Free Port: The binding function is disabled, and the port can learn MAC address freely. 2) Binding: The port is in binding state, and its bound MAC address number is still less than the max number. 3) Secure Port: The port has already bound the max number of MAC address in dynamic binding mode, or it was set to secure port manually in "Port Parameter" page. 4) Unplugged: The port is a SFP port and unplugged yet. The dynamic binding function cannot be configured now. 5) --: The port is a trunk member and its binding function cannot be configured.

Further Explanation

1) If the port is set to secure port manually in "Port Parameter" page, the dynamic binding cannot be configured here. If the port with dynamic binding enabled transfers into secure state automatically because the port has bound the specified number MAC address, the dynamic binding function of the port can be enabled or disabled again. 2) The combo box in "All Ports" entry is used to change the selections of corresponding combo boxes of all ports simultaneously. 3) A "Refresh" button is provided to look up the latest number of bound MAC address.

Notice:

If the switch port is a trunk member or an unplugged SFP port, the binding function of the port cannot be configured here.

5.3.3.5 Bound MAC Address

This page is showed as below:

Figure 5-29 Bound MAC Address

Index: Indicates the entry index in dynamic binding MAC address table. MAC Address: Indicates MAC address already bound to the switch ports. ➢ Port: Indicates the switch port number corresponding to the bound MAC address.

Further Explanation

1) The bound MAC address table contains all the MAC addresses bound by the switch ports. Every entry contains one MAC address and its corresponding port number. 2) The bound MAC address table is divided into several pages. At most 10 entries can be held in one page. The buttons "First", "Previous" and "Next" can be used to browse the whole table.

5.3.3.6 Aging Time

This page is showed as below:

Figure 5-30 Aging Time

Aging Time (0~630): When a new MAC address is learned by the switch, it is added to the dynamic MAC address table and a relative timer is generated immediately. If no packet with that MAC address as its source passes through the switch within a specified time, the MAC address is removed from the table. This process is called "aging," and the specified time is called "aging time."

Further Explanation

1) The aging time ranges from 0 to 630 seconds. An appropriate aging time should be configured. An aging time that is too long delays the deletion of dynamic MAC addresses, which can cause incorrect packet forwarding. An aging time that is too short causes table entries to be deleted quickly, and some packets must be broadcast because no corresponding entries are available. This reduces forwarding efficiency.

If the dynamic MAC address is deleted too early, packets may be forwarded incorrectly. If the aging time is too short, table entries are deleted quickly, and some packets must be broadcast because no corresponding entries are available, reducing forwarding efficiency.

2) The MAC addresses in the static MAC address table, filtering MAC address table, and bound MAC address table are not subject to aging time.

The ping function tests the connectivity of the link between the switch and the destination. This page is shown below:

The ping function is used to test the connectivity of the link between the switch and the destination. This page is shown below:

Destination IP Address: Indicates the IP address of the test destination. Ping Count: Indicates the number of ping attempts in one submission. Data Size: Indicates the data field length of the ping packet. Ping Interval: Indicates the time interval between two consecutive pings.

Destination IP Address: Indicates the IP address of the test destination. Ping Count: Indicates the number of ping times in one submission. Data Size: Indicates the data field length of the ping packet. Ping Interval: Indicates the time interval between two consecutive pings.

5.3.4.1 VLAN Mode

This page selects the VLAN mode. Possible field values are:

This page selects the VLAN Mode. Possible field values are:

VLAN Disable: No VLAN is set on the switch; all ports can communicate with each other. Port VLAN (Port-Based VLAN): Sets Port-Based VLAN mode. Tag VLAN (802.1Q Tag VLAN): Sets 802.1Q Tag VLAN mode. MTU VLAN: Sets MTU VLAN mode. This mode cannot be set if any Trunk has been configured.

VLAN Disable: Do not set any VLAN in the switch, all ports of the switch can communicate with each other. Port VLAN (Port-Based VLAN): Set the Port-Based VLAN mode. Tag VLAN (802.1Q Tag VLAN): Set the 802.1Q Tag VLAN mode. MTU VLAN: Set the MTU VLAN mode. This mode cannot be set if any Trunk has been set.

Select All: Select all ports to be VLAN members. Clean Up: Clean up all members of the VLAN. Submit: Submit to build up a VLAN with the selected members.

Notice:

1) Any VLAN cannot be the subset or superset of other VLANs. 2) At least two port members should be included to add a VLAN group. (If the page is submitted with 0 VLAN member, it indicates to delete the VLAN.) 3) If any Trunk has been set, the Trunk can be configured as a VLAN member, and the member ports of the Trunk cannot be configured (see Port 1 and 2 in the figure for example). 4) For the first time the Port VLAN mode is set, a default VLAN, which is indexed as NO. 1 and contains all switch ports, will be built up. 5) The ports haven't been assigned to any VLAN manually will be assigned to a hidden VLAN automatically to make sure they can communicate with

each other.

6) The number of Port VLANs that can be set is the same as the switch port number.

5.3.4.3 Tag VLAN Global Setting

This page displays when the switch is in Tag VLAN mode. The global setting of the ports will affect all Tag VLANs. It contains the following fields:

Figure 5-35 Tag VLAN Global Setting

Port: The switch port number. ➢ PVID: While receiving an untagged frame from the port, the switch will assign a tag to the frame, using the PVID of the port as its VID. Untag Frame: The solution to the untagged frame received. "Drop" will drop the frame and "Pass" will transmit the frame in the VLAN with the VID the same as the PVID of the port. All Ports: By operating on this field expediently, you can set the values of all ports in the corresponding field.

Notice:

If any Trunk has been set, the Trunk can be configured, but member ports of the Trunk cannot be configured, and in the fields it displays the parameters of the Trunk they belong to (see port1 and 2 in the figure for example).

5.3.4.4 Tag VLAN Setting

This page displays when the switch is in Tag VLAN mode. It configures each VLAN and is affected by the global setting of the ports. It contains the following fields:

Figure 5-36 Tag VLAN Setting

VLAN: The VLAN number. Select the number of the VLAN you want to configure here.

▶ VLAN ID: Configure the VLAN ID. ▶ Port: The switch port number. ➢ Member: Select the member of the VLAN here. If this field is checked, it indicates that the port belongs to the current VLAN. ➢ Egress Frame: The solution to the egress frame. "Drop Tag" indicates drop the tag header before sending the frame. "Add Tag" indicates add the tag header before sending the frame. ➢ Description: Display the user-defined port description. All Ports: By operating on this field expediently, you can set the values of all ports in the corresponding field. All VLAN: Display all defined Tag VLANs.

Figure 5-37 All Tag VLAN

Select All: Select all ports to be VLAN members. Clean Up: Clean up all members of the VLAN. Submit: Submit to build up a VLAN with the selected members.

Notice:

1) VID of the VLAN must be unique and within the range of 1 to 4094. 2) At least two port members should be included to add a VLAN group. (If the page is submitted with 0 VLAN member, it indicates to delete the VLAN.) 3) If any Trunk has been set, the Trunk can be configured as a VLAN member and member ports of the Trunk cannot be configured (see Port 1 and 2 in the figure for example).

4) If the port is connected to a device that doesn't support IEEE802.1Q (e.g. HUB and some network adapter), value of the Egress Frame field should be set to "Drop Tag". 5) For the first time the Port VLAN mode is set, a default VLAN, which is indexed as NO. 1 and contains all switch ports, will be built up. 6) The ports haven't been assigned to any VLAN manually cannot communicate with each other or other VLAN. That's different from the Port VLAN. 7) The number of Port VLAN can be set depends on the switch type. See the Appendix C for details.

5.3.4.5 MTU VLAN Setting

This page, which is designed to configure the uplink port, displays when the switch is in MTU VLAN mode.

Figure 5-38 MTU VLAN Setting

Notice:

1) The uplink port will build up several VLANs with each of the other ports. Each VLAN contains two ports: the uplink port and one of the other ports in the switch, so the uplink port can communicate with any other port, but other ports can't communicate with each other. 2) The first time the MTU VLAN mode is set, it sets port 1 to be the uplink port by default.

5.3.5 Port Trunking

This page contains the following fields:

Figure 5-39 Port Trunking

Trunk: The Trunk number. ➢ Member: Select the member of the Trunk here. Each group has 4 optional ports to compose a Trunk. Select All: Select all Trunk members in the list. Clean Up: Clean up the Trunk member list.

Notice:

1) Each Trunk should contain 2 to 4 ports (If a Trunk is submitted with 0 member port, it indicates to delete the Trunk). 2) Trunks cannot be set if the switch is in MTU VLAN mode.

5.3.6 Priority Setting

Priority setting contains four topics: priority mode, port-based priority, port default priority and 802.1p priority.

Because dynamic menu is adopted, only the pages corresponding to current priority mode are revealed. If the parameters of other priority mode are to be configured, select the corresponding priority mode in “Priority Mode” page first.

5.3.6.1 Priority Mode

This page is showed as below:

Figure 5-40 Priority Mode

➢ Priority Mode: Contains "Disable", "Port-Based" and "IEEE802.1p". ➢ Priority Rule: Contains “Weighted” and “Fixed”. If the priority mode is set to “Disable”, the priority rule cannot be configured.

5.3.6.2 Port-Based Priority

This page is revealed when the "Port-Based" mode is configured. As shown below:

Figure 5-41 Port-Based priority

Port: Indicates the switch port number. Priority Class: In port-based priority mode, the switch ports are classified into four priority classes: lowest, lower, higher, and highest. All the packets

entering from the port of the switch are forwarded in the corresponding priority queue.

Further Explanation

When priority rule is configured as "weighted", a 1,2,4,8 weighting is applied to forward these four classes of packets.

5.3.6.3 Port Default Priority

This page is revealed when the "IEEE802.1p" mode is configured. When a switch port receives an untagged frame (a frame without priority tag), the port's default priority tag will be inserted into the frame before any other process.

Figure 5-42 Port Default Priority

Port: Indicates the switch port number. Default Priority Tag: Indicates 802.1p tag being inserted into untagged frames.

5.3.6.4 802.1p Priority Class

This page is revealed when the "IEEE802.1p" mode is configured. As shown below:

Figure 5-43 802.1p Priority

Priority Tag: The priority tag defined in IEEE802.1p. Corresponding Priority Class: Indicates the inner priority classes of switch. The tagged frames are classified into four classes inside the switch: lowest, lower, higher, and highest. When the "Weighted" priority rule is configured, a 1,2,4,8 weighting is applied to forward these four classes of packets.

Further explanation

In IEEE802.1p priority mode, when a switch port receives an untagged frame (a frame without priority tag), the port's default priority tag will be inserted into the frame before any other process.

5.3.7 Port Mirroring

This page contains the following fields:

Figure 5-44 Port Mirroring

➢ Mirror Mode: You can set the mirror mode to monitor the ingress traffic, egress traffic, or both traffic. You can also disable the port mirroring. ➢ Mirror Port: Defines the port to monitor the traffic, Trunk member can't define here. Mirrored Port: Indicates the port from which the packets are mirrored, Trunk member can't define here. At most 4 ports can be mirrored simultaneously. Clean Up: Clean Up the Mirrored Port list.

Notice:

1) Trunk member port can be neither Mirror Port nor Mirrored Port. 2) The Mirror Port can't be the Mirrored Port at the same time. 3) At most 4 Mirrored Ports can be set. 4) If a 100M SFP module is installed, it can't be the Mirror Port. If it has been configured as the Mirror Port before, please modify it.

5.3.8 Virtual Cable Test

The virtual cable test feature lets you test the continuity of the cable circuit. It contains the following fields:

Figure 5-45 Virtual Cable Test

Test Port: Select the port you want to test.

• Link Status: Reports good status or issues such as cable opens, cable shorts or any impedance mismatch in the cable. ➢ Link Length: Reports the range of the cable length if the link status is good. Fault Distance: Reports the distance to the open/short location. Test: Test the cable via the selected port.

Notice:

Cable connected to the SFP cannot be tested.

Appendix A Pin Explain For RJ-45 Connector

The switching port can connect to stations wired in standard RJ-45 Ethernet station mode using straight cables. Transmission devices connected to each other use crossed cables. The following figure illustrates the pin allocation:

Figure RJ-45 connector. The following shows the way to make the cable used to connect switch to network adapter, and cable used to connect switch to switch/hub/bridge.

Pin signal allocation for RJ-45 connector
Pin MDI-II	MDI-X
1 TX+ (send)	RX+ (receive)
2 TX- (send)	RX- (receive)
3 RX+ (receive)	TX+ (send)
4 No use No	use
5 No use No	use
6 RX- (receive)	TX- (send)
7 No use No	use
8 No use No	use

Straight cable: used to connect switch (uplink port) or network adapter to switch/hub/other device (normal port).
