Description: Configures GARP VLAN Registration Protocol for dynamic VLAN membership distribution across 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 RADLAN-GVRP-MIB?

RADLAN-GVRP-MIB is a private MIB module from RADLAN, an embedded switch-software vendor whose code underlies many OEM switches, defining objects for GARP VLAN Registration Protocol (GVRP) used to dynamically distribute VLAN membership across switch ports. It exposes per-port GVRP timer configuration (join, leave, leave-all timers) as well as protocol statistics counters tracking GVRP PDU activity. It is used to monitor the software/protocol status of GVRP on each port, letting an admin check whether GVRP is supported and enabled (rlGvrpSupported), inspect per-port timer settings, and watch counters like received join-empty (RJE) and received join-in (RJIn) messages to confirm VLANs are propagating correctly. It relies on the IEEE 802.1Q GVRP/GARP standard and typically complements the standard Bridge MIB and Q-BRIDGE-MIB for VLAN management. It is typically deployed on managed Ethernet switches (often OEM/white-label switches built on RADLAN switch software) in enterprise LAN environments using dynamic VLAN registration, and administrators often consult a RADLAN-GVRP-MIB MIB Browser to inspect these objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-GVRP-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

RADLAN-based managed Ethernet switches
OEM/white-label switches (e.g., D-Link)

Monitoring Examples

Using rlPortGvrpTimersTable/rlPortGvrpTimersEntry, an admin can poll rlPortGvrpJoinTime, rlPortGvrpLeaveTime, and rlPortGvrpLeaveAllTime per port to verify GVRP timer configuration matches the network design. The rlPortGvrpStatisticsTable exposes counters like rlPortGvrpStatisticsRJE and rlPortGvrpStatisticsRJIn; a sudden drop in received join messages on a trunk port could indicate a misconfigured or disconnected GVRP neighbor, causing VLANs to fail to propagate. Checking rlGvrpSupported and rlPortGvrpOverrideGarp confirms whether GVRP is active on the device and whether GARP override behavior is in effect on a given port.

What Can Be Monitored

GVRP join/leave/leave-all timer settings
GVRP support/version status
GVRP received join-empty (RJE) counters
GVRP received join-in (RJIn) counters
per-port GARP override setting

How to Use in IPNetwork Monitor

Example using rlPortGvrpStatisticsRJE OID:

Select a RADLAN-based managed Ethernet switches, OEM/white-label switches e.g. D-Link (GARP VLAN Registration Protocol) 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 rlPortGvrpStatisticsRJE 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. The number of Join Empty Received on the port, since the last clearance. 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.
