GARP

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 Layer 2 Management > GARP.

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

Layer 2 Management > GARP

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.

Buttons
  • Apply—modifies attributes and saves the changes.
  • Configure GARP Trace Option—click to access the GARP Traces.

GARP Traces

Figure 2. GARP Traces


Screen Objective This screen allows the user to enable the required debug statements required during debug operation.
Note: Dynamic VLAN should be disabled in the Layer 2 Management > Dynamic VLAN > Dynamic Vlan Global Configuration screen
Navigation

Layer 2 Management > GARP > GARP Configuration 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
Buttons
  • Submit—selects the status of the Global Trace and saves the changes.
  • Apply—modifies attributes and saves the changes.
  • Configure GARP Trace Option—accesses the GARP Configuration screen.
