Description: Manages circuit group and bundle configuration and status on Redback SmartEdge BRAS platforms.

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 RBN-CIRCUIT-GROUP-MIB?

RBN-CIRCUIT-GROUP-MIB is a vendor-specific module for Redback SmartEdge routers that manages and monitors circuit groups/bundles, aggregations of subscriber or transport circuits treated as a single logical unit for policy or statistics purposes. It exposes a statistics table with per-group transmit and receive counters for unicast and multicast octets and packets, as well as counters for adjacency-dropped octets. Its monitoring role is squarely performance-oriented: polling rbnCctGrpTxOctets/rbnCctGrpRxOctets and their packet-count counterparts per rbnCctGrpName reveals throughput trends for a circuit group, while rbnCctGrpAdjDroppedOctets surfaces packets dropped at the adjacency layer, a useful fault indicator for congestion or misconfiguration within that group. It depends on the router's underlying circuit and adjacency infrastructure defined in companion Redback MIBs (such as RBN-BIND-MIB or RBN-BRIDGE-MIB) for circuit membership context. It is typically deployed in broadband/ISP access networks on Redback SmartEdge routers to track aggregate traffic across bundled subscriber or trunk circuits. Engineers can download the RBN-CIRCUIT-GROUP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RBN-CIRCUIT-GROUP-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 administrator would poll rbnCircuitGroupStatsTable/rbnCircuitGroupStatsEntry, tracking rbnCctGrpTxOctets and rbnCctGrpRxOctets per rbnCctGrpName to trend total throughput for a bundled circuit group over time. A rising rbnCctGrpAdjDroppedOctets counter would flag packets being dropped at the adjacency layer for that group, suggesting congestion or a misconfigured policy affecting the bundle. rbnCctGrpTxMulticastPackets and rbnCctGrpRxMulticastPackets would be checked separately when diagnosing multicast delivery issues within the circuit group.

How to Use in IPNetwork Monitor

Example using rbnCctGrpTxOctets OID:

Select a Redback SmartEdge router (circuit-group traffic statistics) 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 rbnCctGrpTxOctets 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 octets transmitted by the group including its children. 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.
