Description: Defines MRV Communications textual convention groups for optical transport management.

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 TC-GROUPS-MIB?

TC-GROUPS-MIB is an MRV Communications enterprise MIB defining Traffic Conditioner (TC) group counters and descriptors for optical transport / switching platforms in MRV's product line. It exposes tables for TC group counters (per group name and action name, with row status), TC group descriptions (free-text labels per group), and TC group results, forming a structure for tracking traffic-policing or shaping group activity. Its monitoring role is chiefly traffic-management and performance status: an operator can check counter and result values against a defined action to see whether traffic conditioning (e.g., policing/marking) for a named group is behaving as expected, which is useful for spotting unexpected drops or marking behavior on a switched port. It relies on MRV's broader switching MIB tree (referenced via nbase/nbSwitchG1 branches) rather than a public IETF standard. It is deployed on MRV Communications optical/Ethernet switching platforms in carrier and enterprise transport networks. Engineers can download the TC-GROUPS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TC-GROUPS-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.

Monitoring Examples

An operator would poll nbTcGrpCntrTable / nbTcGrpCntrEntry to read counters for a specific nbTcGroupCntrGrpName and nbTcGroupCntrActionName, checking whether packets are being conditioned (e.g., marked or dropped) as configured. Cross-referencing nbTcGrpDscrTable's nbTcGroupDscrText for that group name gives the human-readable purpose of the traffic conditioner. Checking nbTcGrpReslTable's nbTcGroupReslStatus for unexpected values would indicate a traffic-conditioning policy is misbehaving or not applying to the intended traffic class.

How to Use in IPNetwork Monitor

Example using nbTcGroupReslMeteringGreens OID:

Select an MRV Communications optical/Ethernet switching platform (traffic-conditioner group counter/status) 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 nbTcGroupReslMeteringGreens 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 metering bytes with green conformance. 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 Counter64-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.
