Configuring a Layer 3 VLAN Interface 

The Layer 3 interface is a VLAN interface. Use the following configuration sequence:

  1. Create a VLAN using the set vlans vlan-id command.
  2. Associate an L3 interface with the VLAN using the set vlans vlan-id l3-interface command.
  3. Configure the IP address and prefix length for the virtual interface using the set l3-interface vlan-interface address prefix-length command.

Note
  • When all the interfaces in a VLAN are link-down, the VLAN interface will be link-down. The VLAN interface will be link-up only when at least one of the member interfaces is link-up.
  • Enable IP routing function before using this feature, for details please refer to Configuring IP Routing.

Configuring the Rate Limiting

L3 VLAN interface rate limit is applied to packets delivered out from the CPU, controlling shock of large flow on CPU, releasing the burden on CPU.
