Huawei AR550 Series - Configuring Sub-Interfaces for Inter-VLAN Communication

To Next Page

To Previous Page

An IP address is assigned to the VLANIF interface for communication at the network layer.

If IP addresses assigned to VLANIF interfaces belong to different network segments, a routing

protocol must be configured on the device to provide reachable routes. Otherwise, VLANIF

interfaces cannot communicate with each other at the network layer.

Step 4 (Optional) Run:

damping time delay-time

The delay period of VLAN damping is configured.

The delay-time value ranges from 0 to 20, in seconds. By default, the delay is 0 second, indicating

that VLAN damping is disabled.

Step 5 (Optional) Run:

mtu mtu

The MTU value of the VLANIF interface is configured.

By default, the value is 1500.

Step 6 (Optional) Run:

bandwidth bandwidth

The bandwidth of the VLANIF interface is configured.

3.6.2.2 Configuring Sub-Interfaces for Inter-VLAN Communication

Context

Users belong to different VLANs and are located on different network segments can

communicate with each other by configuring sub-interfaces.

NOTE

To implement communication between VLANs, hosts in each VLAN must use the IP address of the

corresponding sub-interface as the gateway address.

Procedure

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

interface interface-type interface-number.subinterface-number

The sub-interface view is displayed.

Step 3 Run:

ip address ip-address { mask | mask-length } [ sub ]

The IP address of the sub-interface is set.

Step 4 Run:
