Configuring the VLAN registration mode on the interface

By default, the registration mode for an MVRP-enabled interface is set to Normal. For a static VLAN configuration, the registration mode is automatically set to Fixed. To prune the advertisement propagation and deregistration of a dynamic VLAN on an MVRP-enabled interface port, you can register the VLAN as Forbidden.

Before you begin

This procedure assumes that MVRP is enabled on the device.

Note

You cannot configure a static VLAN as forbidden. If a VLAN is configured in the forbidden list and then it is configured as a static VLAN on the device, this VLAN is implicitly removed from the forbidden list.

1. In privileged EXEC mode, enter global configuration mode.
   

   device# configure terminal

2. Configure an Ethernet interface and access interface configuration mode.
   

   device(config)# interface ethernet 0/9
   

3. Enable MVRP on the interface.
   

   device(conf-if-eth-0/9)# mvrp enable
   

4. Register the VLAN on the forbidden list.
   

   device(conf-if-eth-0/9)# mvrp registration-mode forbidden vlan add 10
   

   You can also provide a range of VLANs.

Example

The following example are the steps in the previous configuration.

device# configure terminal
device(config)# interface ethernet 0/9
device(conf-if-eth-0/9)# mvrp enable
device(conf-if-eth-0/9)# mvrp registration-mode forbidden vlan add 10
