Use show config from the INTERFACE mode to inspect the interface configuration, as shown in Figure 17-4, or use the show gvrp interface command in EXEC or EXEC Privilege mode. Figure 17-4.

For example, if an interface is statically configured via the CLI to belong to a VLAN, it should not be un-configured when it receives a Leave PDU. So, the registration mode on that interface is FIXED. • Forbidden Mode: Disables the port to dynamically register VLANs, and to propagate VLAN information except information about VLAN 1. A port with forbidden registration type thus allows only VLAN 1 to pass through even though the PDU carries information for more VLANs. So, set the interface to the registration mode of FORBIDDEN if you do not want the interface to advertise or learn about particular VLANS. 358 | GARP VLAN Registration Protocol (GVRP)
