Wired Network

Scenarios

Connect to wired networks to add, modify, or delete IP addresses.

Precautions

• When configuring the network, ensure that the configured IP address is correct and does not conflict with other IP addresses on the network. Configure IP addresses in different network segments for different NICs. Otherwise, the network is abnormal.
• During network configuration, if two network ports are connected to the same LAN, modify the system configuration before modifying the network configuration. Otherwise, the two NICs on the same server may conflict with each other.
  1. Log in to the backend CLI of the edge device over SSH.
  2. Run the vi /etc/sysctl.conf command to add configuration items net.ipv4.conf.all.arp_ignore=1 and net.ipv4.conf.all.arp_announce=2. Then, run the :wq command to save the settings and exit.
  3. Run the sysctl -p command to make the new configuration take effect.
• After the network configuration is complete, the Nginx service will restart. After the restart is complete, the new configuration takes effect and the function is restored. When using the SmartKit to configure the network, add an interval (more than 10s is recommended) between adjacent operations.
• When configuring the default gateway for network ports 1–4, add a management route for network port 0 to prevent the device from being unreachable by the NMS. Run the route add -net <Management IP address>/<Number of subnet mask bits> gw <Default gateway of network port 0> <Network port 0> command to add the route.

Checking the Wired Network

1. Choose Management > Network Configuration > Wired Network.
   Figure 1 Wired network configuration
   
2. Select the network port for configuring the network, network port 0 or network ports 1–4.
   • Network port 0 corresponds to of the device hardware.
   • Network ports 1–4 correspond to , , , and of the device hardware.
3. Click Check.

   Connected 1000Mb/s after Check Network Status is the latest network status detected by the system.

Adding an IP Address

1. Choose Management > Network Configuration > Wired Network.
   Figure 3 Wired network configuration
   
2. Select the network port for configuring the network, network port 0 or network ports 1–4.
   • Network port 0 corresponds to of the device hardware.
   • Network ports 1–4 correspond to , , , and of the device hardware.
3. Click Configure IP Address. The IP Address dialog box is displayed.
   Figure 4 Adding an IP address
   
4. Set the IP address parameters by referring to Table 1.
5. Click Confirm to save the configuration.
6. Click Save to make the configuration take effect.

Modifying the IP Address Information

• Modifying an IP address will interrupt services on the network port. Exercise caution when performing this operation.
• Modifying IP addresses is risky. The operator must have related network knowledge and modify the IP addresses according to the network plan and operation guide.

1. Choose Management > Network Configuration > Wired Network.
   Figure 6 Wired network configuration
   
2. Select the network port for configuring the network, network port 0 or network ports 1–4.
   • Network port 0 corresponds to of the device hardware.
   • Network ports 1–4 correspond to , , , and of the device hardware.
3. Click Modify in the row of the IP address to be modified.
   Figure 7 Modifying the IP address information
   
4. In the IP Address dialog box, modify the parameters related to the IP address. For the parameter description, see Table 1.
   Figure 8 Modifying the IP address information
   
5. Click Confirm to save the modification.
6. Click Save to make the configuration take effect.

Deleting an IP Address

• A deleted IP address cannot be restored. Exercise caution when performing this operation.
• If the network port has only one IP address, this IP address can be modified but cannot be deleted.

1. Choose Management > Network Configuration > Wired Network.
   Figure 10 Wired network configuration
   
2. Select the network port for configuring the network, network port 0 or network ports 1–4.
   • Network port 0 corresponds to of the device hardware.
   • Network ports 1–4 correspond to , , , and of the device hardware.

3. Locate the IP address to be deleted and click Delete in the Operations column. A confirmation dialog box is displayed.
   Figure 11 Deleting an IP address
   
   

   If you delete the only IP address in the configured IP address area, the system displays a message indicating that the IP address cannot be empty.

4. Click Confirm to delete the IP address.
5. Click Save to make the configuration take effect.
