Quidway S6500 Series Ethernet Switches
GARP and GMRP are described in details in the IEEE 802.1p standard (which has
been added to the IEEE802.1D standard). Quidway Series Ethernet Switches fully
support the GARP compliant with the IEEE standards.
Main GARP configuration includes:
Set GARP timer
Note:
The value of GARP timer will be used in all the GARP applications, including GVRP
and GMRP, running in one switching network.
In one switching network, the GARP timers on all the switching devices should be
set to the same value. Otherwise, GARP application cannot work normally.
2.1.2 Set GARP Timer
GARP timers include Hold timer, Join timer, Leave timer and LeaveAll timer.
The GARP participant sends Join Message regularly when Join timer timeouts so that
other GARP participants can register its attribute values.
When the GARP participant wants to remove some attribute values, it will send Leave
Message outward. The GARP participant receiving the information will start the Leave
timer. If Join Message is not received again before the Leave timer expires, the GARP
attribute values will be removed
LeaveAll timer will be started as soon as the GARP participant is enabled. LeaveAll
message will be sent upon timeout so that other GARP participants will remove all the
attribute values of this participant. Then, Leaveall timer is restarted and a new cycle
begins.
When the switch receives some GARP registration information, it will not send Join
Message immediately. Instead, it will enable a hold timer and send the Join Message
outward upon timeout of the hold timer. In this way, all the VLAN registration information
received within the time specified by the Hold timer can be sent in one frame so as to
save the bandwidth resource.
Configure Hold timer, Join timer and Leave timer in Ethernet port view. Configure
LeaveAll timer in system view.
