GARP Port Configuration
 To configure a GARP port:
1. Select Switching> VLAN > Advanced > GARP Port Configuration. The GARP Port
Configuration table is displayed.
2. To navigate the page, select one of the following links. For more navigation information, see
Configuring Interface Settings on page 32.
• To display all of the physical ports, click the 1 link.
• To display all LAGs, click the LAGS link.
• To display all ports and LAGs, click the All link.
• To select a single interface, type the port number, for example g4, in the Go To
Interface field. Click the Go button.
3. Click a check box to select a physical interface for which data is to be displayed or
configured.
4. Configure the Port GVRP Mode. Choose the GARP VLAN Registration Protocol
administrative mode for the port by selecting Enable or Disable from the list. If you select
Disable, the protocol will not be active and the Join Time, Leave Time and Leave All Time
will have no effect. The factory default is Disable.
5. Configure the Join Timer (centiseconds). Specify the time between the transmission of
GARP PDUs registering (or re-registering) membership for a VLAN or multicast group in
centiseconds. Enter a number between 10 and 100 (0.1 to 1.0 seconds). The factory default
is 20 centiseconds (0.2 seconds). An instance of this timer exists for each GARP participant
for each port.
6. Configure the Leave Timer (centiseconds). Specify the time to wait in centiseconds, after
receiving an unregister request for a VLAN or multicast group, before deleting the
associated entry. This allows time for another station to assert registration for the same
attribute in order to maintain uninterrupted service. Enter a number between 20 and 600 (0.2
to 6.0 seconds). The factory default is 60 centiseconds (0.6 seconds). An instance of this
timer exists for each GARP participant for each port.
7. Configure the Leave All Timer (centiseconds). The Leave All Time controls how frequently
LeaveAll PDUs are generated. A LeaveAll PDU indicates that all registrations will shortly be
deregistered. Participants will need to rejoin in order to maintain registration. The Leave All
Period Timer is set to a random value in the range of LeaveAllTime to 1.5 x LeaveAllTime.
The timer is specified in centiseconds. Enter a number between 200 and 6000 (2 to 60
seconds). The factory default is 1000 centiseconds (10 seconds). An instance of this timer
exists for each GARP participant for each port.
8. Click the Apply button to send the updated configuration to the switch. Configuration
changes take effect immediately.
Note: It can take up to 10 seconds for GARP configuration changes to take
effect.
9. Click the Cancel button to cancel the configuration on the screen, and reset the data on the
screen to the latest value of the switch.
