This section describes how to configure GARP on the switch.
GARP (Generic
Attribute Registration Protocol) is used to synchronize attribute
information between the bridges in the LAN. It allows to register
and de-register attribute values, which are disseminated into the backbone
of the GARP participants.
To access GARP screens, go to .
GARP Configuration
Figure 1. GARP Configuration

Screen Objective |
This screen allows the user to enable GARP status in the Virtual contexts
created in the system. |
Note: To shutdown the GARP functionality: - Dynamic VLAN should be disabled in the
Layer 2 Management > Dynamic VLAN > Dynamic Vlan Global Configuration
screen
- Dynamic Multicast should be disabled using Multicast > GMRP
> GMRP Global Configuration screen
|
Navigation |
|
Fields |
- Select—click
to select the context for starting or shutting down GARP module.
- Context—displays the virtual context
ID that uniquely represents a virtual switch created in the physical
switch. This value ranges from 0 to 65535. The default value is
0.
|
Fields (cont) |
- GARP Status—select
status requested by management for GARP.
The default option is Start for the default context ID (0) and Shutdown
for other context IDs. The list contains:
- Start—enables GARP in the switch on all ports. GMRP and GVRP are enabled
explicitly, once the disabled GARP is
enabled.
- Shutdown—disables GARP in
the switch on all ports
Note: To shutdown GARP functionality, Dynamic VLAN and Multicast should be disabled
in the Dynamic VLAN and GMRP Global Configuration screens.

screen.
Click Configure
GARP Trace Options button.
|
Fields |
- GARP Global Trace—select
the global status of the GARP trace
to set the VLAN trace status
for all virtual switches in the switch. The list contains:
- ENABLE—enables
the GARP traces in the switch
for all virtual switches. The debug statement is generated for the
selected traces.
- DISABLE—disables the GARP traces
in the switch for all virtual switches. The debug statement is not
generated for any of the traces, even if the specific trace is selected.
- Select—click to select the context for
which the trace levels need to be set.
- Context—displays the virtual context
ID that uniquely represents a virtual switch created in the physical
switch. This value ranges from 0 to 65535. The default value is
0.
- Debug Trace Options—select traces for
which debug statements is needed:
- Init-Shut—generates debug
statements for init and shutdown traces. This trace is generated
on failed initialization and shutting down of GARP related entries.
- Management—generates debug statements for management traces. This
trace is generated during failure in configuration of any of the GARP features.
- Memory—generates debug statements for data path traces. This
trace is generated during failure in packet processing.
- BPDU—generates debug statements for BPDU traces.
This trace is generated during failure in modification or retrieving
of GARP entries.
- Events—generates debug statements for packet dump traces. This trace
is currently not used in GARP module.
- Timer—generates debug statements for OS resource related traces. This
trace is generated during failure in message queues.
- All-Failures—generates debug statements for all failure traces
of the above-mentioned traces.
- Buffer—generates debug statements for GARP buffer
related traces. This trace is currently not used in GARP module.
- Debug Module Options—select the module
for which debug statements is to be generated. The options are:
- GARP—Generates the debug statements for the GARP module.
- GMRP—Generates the debug statements for the GMRP module.
- GVMRP—Generates the debug statements for the GVRP module.
- Redundancy—Generates the debug statements for the GARP redundancy module
