GVRP and Bridge Extension Commands
GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in
order to automatically register VLAN members on interfaces across the network. This section
describes how to enable GVRP for individual interfaces and globally for the switch, as well as how to
display default configuration settings for the Bridge Extension MIB.This section describes how to
display default configuration settings for the Bridge Extension MIB.
Note: Under the following condition, GVRP does not leave and join dynamically. In LAB testing,
tagged frames transmitted at wire speed, dynamically changing the VLAN tag information from
VLAN ID 1 to 128, results in GVRP failing after 10 to 20 minutes.
