Username	admin
Password

• iLinksView is enabled by default, and the default username is admin, the default password is lt_91_il_02_nmp.
• When using the iLinksView to manage the device, note that the username and password must be the same as that you have set in the iLinksView, otherwise the iLinksView cannot discover the device.

4.3 VLAN Configuration

VLAN (Virtual Local Area Network) is frequently used during actual application; it is divided into multiple network basics internally. VLAN is to organize several devices into one network logically, regardless of the physical location of the devices. Each VLAN is a logical network, which is equipped with all functions and attributes of traditional physical network. Each VLAN is a broadcast domain; broadcast packet can only be forwarded within one VLAN, not across the VLAN.

VLAN Based on Port

VLAN based on port means that one switch can realize the division of logical working groups via controlling interoperability of between two and among several ports. Dividing port VLAN reasonably can greatly improve network security and bandwidth use ratio, besides it reduces the probability of broadcast storm. The model supports 4094 VLAN; it needs to select a VLAN

ID when creating VLAN, ranging from 2 to 4094. The switch creates VLAN1 by default and VLAN1 cannot be deleted.

Application Example

Networking Requirement

There are two users, user 1 and user 2. These two users need to be in different VLAN due to different network function and environment. User 1 belongs to VLAN2, connecting to switch port G1/1 (Gigabit Ethernet 1/1); user 2 belongs to VLAN 3, connecting to switch port G1/2 (Gigabit Ethernet 1/2).

Figure 4-2 VLAN networking

Configuration Steps

The switch configuration is shown as follows.

1. Log in to the device. Refer to "4.1 First Login by Console Port".
2. Run the following command to create VLAN.

SWITCH #configure terminal

SWITCH (config)#vlan 2

SWITCH (config-vlan)# exit

SWITCH (config)#vlan 3

SWITCH (config)# interface GigabitEthernet 1/1

SWITCH (config-if)# switchport access vlan 2

SWITCH (config-if)# exit

SWITCH (config)# interface GigabitEthernet 1/2

SWITCH (config-if)# switchport access vlan 3

SWITCH (config-if)# exit

Appendix 1 Cybersecurity Recommendations

Cybersecurity is more than just a buzzword: it's something that pertains to every device that is connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic steps toward protecting and strengthening networks and networked appliances will make them less susceptible to attacks. Below are some tips and recommendations on how to create a more secured security system.

Mandatory actions to be taken for basic device network security:

1. Use Strong Passwords

Please refer to the following suggestions to set passwords:

• The length should not be less than 8 characters;
• Include at least two types of characters; character types include upper and lower case letters, numbers and symbols;
• Do not contain the account name or the account name in reverse order;
• Do not use continuous characters, such as 123, abc, etc.;
• Do not use overlapped characters, such as 111, aaa, etc.;

2. Update Firmware and Client Software in Time

• According to the standard procedure in Tech-industry, we recommend to keep your device (such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped with the latest security patches and fixes. When the device is connected to the public network, it is recommended to enable the “auto-check for updates” function to obtain timely information of firmware updates released by the manufacturer.
• We suggest that you download and use the latest version of client software.

"Nice to have" recommendations to improve your device network security:

1. Physical Protection

We suggest that you perform physical protection to device, especially storage devices. For example, place the device in a special computer room and cabinet, and implement well-done access control permission and key management to prevent unauthorized personnel from carrying out physical contacts such as damaging hardware, unauthorized connection of removable device (such as USB flash disk, serial port), etc.

2. Change Passwords Regularly

We suggest that you change passwords regularly to reduce the risk of being guessed or cracked.

3. Set and Update Passwords Reset Information Timely

The device supports password reset function. Please set up related information for password reset in time, including the end user's mailbox and password protection questions. If the information changes, please modify it in time. When setting password protection questions, it is suggested not to use those that can be easily guessed.

4. Enable Account Lock

The account lock feature is enabled by default, and we recommend you to keep it on to guarantee the account security. If an attacker attempts to log in with the wrong password several times, the corresponding account and the source IP address will be locked.

5. Change Default HTTP and Other Service Ports

We suggest you to change default HTTP and other service ports into any set of numbers between 1024\~65535, reducing the risk of outsiders being able to guess which ports you are using.

6. Enable HTTPS

We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel.

7. MAC Address Binding

We recommend you to bind the IP and MAC address of the gateway to the device, thus reducing the risk of ARP spoofing.

8. Assign Accounts and Privileges Reasonably

According to business and management requirements, reasonably add users and assign a minimum set of permissions to them.

9. Disable Unnecessary Services and Choose Secure Modes

If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to reduce risks.

If necessary, it is highly recommended that you use safe modes, including but not limited to the following services:

• SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication passwords.
• SMTP: Choose TLS to access mailbox server.
• FTP: Choose SFTP, and set up strong passwords.
• AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords.

10. Audio and Video Encrypted Transmission

If your audio and video data contents are very important or sensitive, we recommend that you use encrypted transmission function, to reduce the risk of audio and video data being stolen during transmission.

Reminder: encrypted transmission will cause some loss in transmission efficiency.

11. Secure Auditing

• Check online users: we suggest that you check online users regularly to see if the device is logged in without authorization.
• Check device log: By viewing the logs, you can know the IP addresses that were used to log in to your devices and their key operations.

12. Network Log

Due to the limited storage capacity of the device, the stored log is limited. If you need to save the log for a long time, it is recommended that you enable the network log function to ensure that the critical logs are synchronized to the network log server for tracing.

13. Construct a Safe Network Environment

In order to better ensure the safety of device and reduce potential cyber risks, we recommend:

• Disable the port mapping function of the router to avoid direct access to the intranet devices from external network.
• The network should be partitioned and isolated according to the actual network needs. If there are no communication requirements between two sub networks, it is suggested to use VLAN, network GAP and other technologies to partition the network, so as to achieve the network isolation effect.
• Establish the 802.1x access authentication system to reduce the risk of unauthorized access to private networks.
• Enable IP/MAC address filtering function to limit the range of hosts allowed to access the device.
