OmniSwitch AOS Release 6 Network Configuration Guide

A switch in the GVRP transparent mode floods GVRP frames to other switches transparently when GVRP 
is globally disabled on the switch. However, the switch does not advertise or synchronize its VLAN 
configuration based on received VLAN advertisements. By default, transparent switching is disabled on 
the switch.

Note. If GVRP is globally enabled on a switch, transparent switching will have no effect on the switch.

You can configure the switch to propagate GVRP frames transparently using the 

 command, as shown:

-> gvrp transparent switching

Use the no form of this command to disable the transparent switching capability of the switch. For exam-
ple:

-> no gvrp transparent switching

Note. When both GVRP and GVRP transparent switching are globally disabled, the switch will discard the 
GVRP frames.

A switch can create dynamic VLANs using GVRP. By default, the maximum number of dynamic VLANs 
that can be created using GVRP is 1024. If the VLAN limit to be set is less than the current number of 
dynamically learned VLANs, then the new configuration will take effect only after the GVRP is disabled 
and enabled again on the switch. If this operation is not done, the VLANs learned earlier will be main-
tained. To modify the maximum number of dynamic VLANs the switch is allowed to create, use the 

 command as shown:

-> gvrp maximum vlan 150

Here, the number of dynamic VLANs the switch can create is set to a maximum of 150.

Note. A maximum of 4094 dynamic VLANs can be created using GVRP.

These dynamically created VLANs do not support the following operations:

• Authentication 

• IP routing 

• IPX routing 

• Configuring default VLAN on any port

• Enabling/Disabling classification of tagged packets received on mobile ports (vlan mobile-tag)
