Category: Device Management

Description: Defines managed objects for the General Switch Management Protocol (GSMP), which allows a controller to establish and release connections across a switch.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring GSMP-MIB with a free 30-day trial of IPNetwork Monitor.

What Is GSMP-MIB?

GSMP-MIB defines managed objects for the General Switch Management Protocol (GSMP) version 3, a standards-based IETF protocol that allows an external controller to establish, manage, and release connections across a switch, as used historically in ATM and label-switching architectures. It belongs to the switch-control/label-switching protocol technology area. Its data would cover GSMP session and adjacency state, controller-to-switch connection establishment status, and protocol statistics between a GSMP controller and its managed switch(es), reflecting protocol/software operational status rather than physical hardware sensors. Consulting the GSMP-MIB OID list is useful mainly for confirming which session, adjacency, and connection objects a controller-side NMS can poll. It supports monitoring of software/protocol status by exposing whether a GSMP adjacency between controller and switch is up, and the state of individual switch connections established via the protocol, which is central to detecting a broken controller-switch relationship. It is a direct implementation of the IETF GSMPv3 standard (RFC 3294/3295 family) and depends on standard SNMPv2 conventions rather than any vendor-specific MIB tree. It is deployed in legacy ATM/MPLS-controller architectures where a separate controller manages switching fabric via GSMP.

IPNetwork Monitor allows you to monitor SNMP objects defined in GSMP-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

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer — applies to ATM/MPLS switches under GSMP controller management

Monitoring Examples

No sample objects were supplied for GSMP-MIB, so specific table/object names cannot be verified; conceptually a controller-side NMS would poll GSMP adjacency and connection-state objects to confirm a switch remains under active GSMP control and that established connections have not been unexpectedly torn down, but exact object names cannot be confirmed without the module's data definitions.

How to Use in IPNetwork Monitor

Example using gsmpSessionTimer OID:

Select a device implementing GSMP-MIB 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 gsmpSessionTimer 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, in units of 100 milliseconds, the time remaining before this GSMP adjacency's timer expires. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drops close to or below 0, which means the adjacency is about to (or has already) expired. Click Finish to create the monitor; you can adjust any parameter later.
