Configuring GVRP Chapter 13 Configuring GVRP To enable GVRP on individual 802.1Q-capable ports, perform this task in privileged mode: Step 1 Step 2 Task Enable GVRP on an individual 802.1Q-capable port. Verify the configuration. Command set port gvrp enable mod_num/port_num show gvrp configuration This example shows how to enable GVRP on 802.1Q-capable port 1/1: Console> (enable) set port gvrp enable 1/1 GVRP enabled on 1/1. Console> (enable) Enabling GVRP Dynamic VLAN Creation You can enable GVRP dynamic VLAN creation only if these conditions are met: • The switch is in VTP transparent mode • All trunk ports on the switch are 802.1Q trunks • GVRP is enabled on all trunk ports Note Dynamic VLAN creation supports all VLAN types. If you enable dynamic VLAN creation, these configuration restrictions are imposed: • You cannot change the switch to VTP server or client mode • You cannot disable GVRP on a trunk port running GVRP If any port on the switch becomes an ISL trunk (either by CLI configuration or negotiated using DTP while dynamic VLAN creation is enabled), dynamic VLAN creation is automatically disabled until the conditions for enabling dynamic VLAN creation are restored. Note VLANs can only be created dynamically on 802.1Q trunks in the normal registration mode. To enable GVRP dynamic VLAN creation on the switch, perform this task in privileged mode: Step 1 Step 2 Task Enable dynamic VLAN creation on the switch. Verify the configuration. Command set gvrp dynamic-vlan-creation enable show gvrp configuration This example shows how to enable dynamic VLAN creation on the switch: Console> (enable) set gvrp dynamic-vlan-creation enable Dynamic VLAN creation enabled.
