Configuring GVRP
Command Line version
This section describes the commands to implement the GVRP protocol.
Important:
GVRP Timers - The Switch issues GVRP PDUs to other 802.1Q devices to update VLAN membership
information dynamically. These 802.1Q devices use this information to add and delete dynamic VLANs or
add and delete ports to an existing VLAN. The Switch sends these PDUs at the time intervals specified in
the IEEE standard. We recommend that you do not change these settings. Doing so can have a
serious impact on network performance.
●
Configuring GVRP
Enable the GVRP protocol on the Switch. The default is disable:
>set gvrp [enable | disable]
Example: set gvrp enable
1.
To see whether GVRP is enabled on the Switch:
>show gvrp
Example: show gvrp
2.
To enable GVRP for one or more ports:
>set port gvrp-status <port_number> [enable | disable]
Example: set port gvrp-status 25 enable
3.
To see whether GVRP is enabled on a port:
>show port gvrp-status <port_number>
Example: show port gvrp-status 25
4.
The command described below sets the time interval that the Switch uses before issuing updates to other
devices. We do not recommend changing these timers.
If you must change the default settings, follow these rules:
The value for leave must be at least three times greater than the value for join.
❍
The value for leaveall must be greater than the value for leave.❍
The time values on all connected devices must be identical for GVRP to operate successfully.
>set gvrp timer [leaveall | leave | join] <port_number> <timer_value>
Example: >set garp timer leaveall 2 1
Example: >set gvrp timer join 2 1
leaveall: a message issued when all ports no longer belong to the VLAN and the VLAN should be
deleted
leave: a message issued when a single port no longer belongs to the VLAN
join: a message issued when a new port has been added to the VLAN
timer_value is in milliseconds
❍
5.
To see the join, leave, or leaveall timer to the timer value for a specific port:
>show gvrp timer <port_number>
Example: show gvrp timer 25
