Description: Manages GARP VLAN Registration Protocol (GVRP) on D-Link 3100 series switches for dynamic VLAN membership propagation.

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 DLINK-3100-GVRP-MIB?

DLINK-3100-GVRP-MIB is a D-Link proprietary module for the 3100 series switches implementing GARP VLAN Registration Protocol (GVRP), which dynamically propagates VLAN membership information between switches. It exposes per-port GVRP timer configuration (join, leave, and leave-all timers), an override flag for underlying GARP settings, and per-port GVRP protocol statistics such as received join-empty (RJE) and received join-in (RJIn) message counts. Its monitoring value is centered on the software/protocol status of dynamic VLAN propagation -- letting an administrator confirm GVRP is supported and enabled (rlGvrpSupported), check the timer configuration driving how quickly VLAN membership changes propagate, and use the statistics counters to verify GVRP messages are actually being exchanged on a port rather than silently failing. It is a vendor extension built on top of the standard GARP/GVRP protocol model defined in IEEE 802.1Q. It is typically deployed on D-Link 3100 series switches in networks relying on dynamic rather than statically configured VLAN trunking. Engineers can download the DLINK-3100-GVRP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-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

D-Link 3100 series switch

Monitoring Examples

An administrator would check rlGvrpSupported and per-port rlPortGvrpTimersTable (rlPortGvrpTimersEntry) values -- rlPortGvrpJoinTime, rlPortGvrpLeaveTime, rlPortGvrpLeaveAllTime -- to confirm GVRP timers match the intended propagation speed, then review rlPortGvrpStatisticsTable (rlPortGvrpStatisticsEntry) counters like rlPortGvrpStatisticsRJE and rlPortGvrpStatisticsRJIn to verify GVRP PDUs are being received on a trunk port. A port showing zero incrementing RJE/RJIn counts despite an active neighbor would indicate GVRP is not actually negotiating VLAN membership on that link, pointing to a protocol or cabling issue.

How to Use in IPNetwork Monitor

Example using rlPortGvrpStatisticsRJE OID:

Select a D-Link 3100 series switch (DES/DGS-3100), GVRP dynamic VLAN registration 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.
