Description: Huawei GARP application MIB for managing GARP (Generic Attribute Registration Protocol) applications including GVRP and GMRP on Ethernet switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is HUAWEI-GARP-APP-MIB?

HUAWEI-GARP-APP-MIB is a Huawei private MIB for configuring and monitoring GARP (Generic Attribute Registration Protocol) applications, specifically GVRP (VLAN registration) and GMRP (multicast group registration), on Ethernet switches. It exposes configuration objects for these GARP applications along with related statistics counters. Its monitoring value is in confirming that dynamic VLAN and multicast group registration is functioning correctly across switch ports, and in reviewing GARP protocol statistics (e.g., registrations, join/leave events) to detect registration churn or protocol errors. It builds directly on the standard IEEE 802.1D GARP framework and interacts with the bridge/VLAN MIBs since GVRP/GMRP dynamically modify VLAN and multicast group membership. It is deployed on Huawei enterprise/campus Ethernet switches using dynamic VLAN or multicast registration instead of static configuration, and administrators can download the HUAWEI-GARP-APP-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-GARP-APP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Huawei enterprise/campus Ethernet switches

Monitoring Examples

An administrator would check per-port GARP application statistics to see the count of GVRP join/leave messages processed, helping confirm that a downlink switch is correctly propagating VLAN membership dynamically. An unusually high rate of GARP timeouts or failed registrations on a port would indicate a misconfigured timer or an incompatible neighbor device. GMRP statistics similarly help confirm multicast group registrations are propagating as expected across the switched network.

What Can Be Monitored

GVRP/GMRP enable configuration
per-port GARP registration statistics
GARP join/leave/timeout counters

How to Use in IPNetwork Monitor

Example using hwGarpAppSwitchGmrpRxPkt OID:

Select a Huawei Ethernet switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hwGarpAppSwitchGmrpRxPkt into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the number of GMRP frames received. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
