Configuring Device Information 301
Configuring GARP
Generic Attribute Registration Protocol (GARP) 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, GARP application does not operate successfully.
To open the GARP page, click Switch→ GARP in the tree view.
Defining GARP Timers
The GARP Timers page contains fields for enabling GARP on the device. To open the GARP Timers
page, click Switch→ GARP → GARP Timers in the tree view.
