How can I obtain switch configurations through an NMS when the IP address of the NMS is on a VPN

4

Solution
When an NMS manages a switch through a VPN, switch management information needs to be sent to the NMS through a VPN instance.
You can run the set net-manager vpn-instance command to configure the default VPN instance for the NMS to manage the switch so that the switch can use this VPN instance to communicate with the NMS.

Precautions
- Before running this command, ensure that a VPN instance has been created successfully on the switch.
- After this command is configured, commands that you have configured for file transfers over FTP, TFTP, or SFTP only take effect in the default VPN instance.
- If the switch has been configured as a log host, the NMS can receive logs from the switch through the default VPN instance.

Change the management IP address of the S1728GWR-4P switch
Change the management IP address of an S1728GWR-4P switch as follows: Choose System > IP. On the page displayed, configure the switch information such as the management VLAN and IP address. By default, the switch obtains an IP address through DHCP. If the switch fails to obtain an IP address through DHCP, the switch uses the IP address of 192.168.0.1. Perform the following operation to configure the switch to obtain an IP address through DHCP: 1. Choose System > IP. 2. Specify an available management VLAN for the switch and set IP地址方式 to DHCP. 3. Click Apply to save the configuration. 4. Click Restart DHCP to obtain a new IP address. Perform the following operations to configure a static IP address for the switch: 1. Choose System > IP. 2. Specify an available management VLAN for the switch, set IP Address Mode to Static, and enter an IP address, subnet mask, and gateway IP address. 3. Click Apply to save the configuration.

Can the IP address used to log in to an AR router through the web NMS be an IP address of a VLANIF interface
For AR120 & AR150 series, Eth0/0/0 to Eth0/0/3 are Layer 2 Ethernet interfaces by default, added to VLANIF 1, and configured with a default management IP address 192.168.1.1/24. The AR routers support web NMS access through any interface of the VLANIF based on this IP address. Run the undo portswitch command to change the mode of the Eth0/0/0 to Eth0/0/3 from Layer 2 to Layer 3. After the management network interface is switched over to the Layer 3 mode, configure the management IP address for the management network interface, and then log in to the web NMS.

The AR routers support web NMS access through any interface of the VLANIF based on this IP address. Run the undo portswitch command to change the mode of the GE0/0/0 to GE0/0/3 from Layer 2 to Layer 3. After the management network interface is switched over to the Layer 3 mode, configure the management IP address for the management network interface, and then log in to the web NMS. For AR200 series, AR1220, AR1220V, AR1220W, AR1220VW, and AR1220F, Eth0/0/0 to Eth0/0/7 are Layer 2 Ethernet interfaces by default, added to VLANIF 1, and configured with a default management IP address 192.168.1.1/24. The AR routers support web NMS access through any interface of the VLANIF based on this IP address. Run the undo portswitch command to change the mode of the Eth0/0/0 to Eth0/0/7 from Layer 2 to Layer 3. After the management network interface is switched over to the Layer 3 mode, configure the management IP address for the management network interface, and then log in to the web NMS. For AR2201-48FE and AR2202-48FE, Eth0/0/0 to Eth0/0/47 are Layer 2 Ethernet interfaces by default, added to VLANIF 1, and configured with a default management IP address 192.168.1.1/24. The AR routers support web NMS access through any interface of the VLANIF based on this IP address. Run the undo portswitch command to change the mode of the Eth0/0/0 to Eth0/0/47 from Layer 2 to Layer 3.
