Defining GARP
Generic Attribute Registration Protocol (GARP) protocol is a general-purpose protocol that registers any network
connectivity or membership-style information. GARP defines a set of devices interested in a given network
attribute, such as VLAN or multicast address. When configuring GARP, ensure the following:
•
The leave time must be greater than or equal to three times the join time.
•
The leave-all time must be greater than the leave time.
•
Set the same GARP timer values on all Layer 2-connected devices. If the GARP timers are set differently on
the Layer 2-connected devices, the GARP application does not operate successfully.
To define GARP on the device:
1. Click Basic Setup > VLAN > GARP > GARP Parameters . The GARP Parameters Page opens:
Figure 43: GARP Parameters Page
The GARP Parameters Page contains the following fields:
•
Unit No. — Displays the stacking member for which the GARP parameters are displayed.
•
Interface — Displays the port or LAG on which GARP is enabled.
•
Join Timer — Indicates the amount of time, in centiseconds, that PDUs are transmitted. The default value is
20 centiseconds.
•
Leave Timer — Indicates the amount of time lapse, in centiseconds, that the device waits before leaving its
GARP state. Leave time is activated by a Leave All Time message sent/received, and cancelled by the Join
