Description: Manages IS-IS routing protocol configuration, adjacencies, and LSP database on Nortel Ethernet Routing Switch 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 RC-ISIS-MIB?

RC-ISIS-MIB is a Nortel Networks enterprise MIB for the Ethernet Routing Switch (Accelar/Rapid-City) family, covering configuration and operational monitoring of the IS-IS interior gateway routing protocol. It exposes IS-IS authentication settings (area and domain key/type), protocol timers (CSNP/PSNP intervals, LSP retransmit interval, SPF delay), host name and control-VLAN configuration, plus dedicated statistics and trap groups. Its main monitoring value is around routing-protocol software health: tracking rcIsisStats to catch abnormal LSP retransmissions or SPF recalculation frequency, and rcIsisTrap notifications to detect adjacency changes or authentication failures that would disrupt routing convergence. It complements (without directly depending on) the IETF's standard ISIS-MIB, implementing IS-IS management as a Nortel enterprise equivalent. It is deployed on Nortel Ethernet Routing Switches acting as IS-IS routers in enterprise or metro networks requiring resilient interior routing. Engineers can download the RC-ISIS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-ISIS-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 engineer would monitor rcIsisStats and rcIsisTrap to detect flapping adjacencies or repeated SPF recalculations (tied to rcIsisGlobalSpfDelay) that could indicate an unstable link or misconfigured neighbor. Checking rcIsisGlobalRxmtLspInt and rcIsisGlobalCsnpInt against expected defaults helps confirm the router's LSP/CSNP timers haven't been misconfigured, which could otherwise cause slow convergence. If rcIsisGlobalAreaAuthType or rcIsisGlobalDomainAuthType mismatches between peers, IS-IS adjacencies would fail to form, visible via authentication-failure traps.

What Can Be Monitored

IS-IS adjacency/routing statistics
LSP retransmission and refresh intervals
SPF recalculation delay
IS-IS authentication configuration
IS-IS fault traps
