CISCO-CIRCUIT-INTERFACE-MIB

Description: Manages circuit-mode network interfaces on Cisco devices, providing configuration and status for dedicated circuit connections.

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.

This Cisco private MIB provides a simple mechanism to attach a human-readable description to individual circuit-oriented interfaces, such as ATM or Frame Relay interfaces, on Cisco routers. It exposes a small configuration table mapping an interface to a free-text description and the row status of that description entry. Its monitoring value is administrative/inventory rather than deep hardware or software health: it lets an operator confirm the correct label is applied to a circuit and that the description entry itself is active, which is useful for auditing and identifying circuits during troubleshooting. It augments the standard IF-MIB (RFC 2863) ifTable, since each circuit description entry is tied to a specific interface's ifIndex. It is deployed on Cisco WAN edge routers carrying many ATM or Frame Relay circuits where clear per-circuit labeling aids operational troubleshooting. Engineers can download the CISCO-CIRCUIT-INTERFACE-MIB file directly to load it into their MIB browser.

An admin would poll cciDescriptionTable/cciDescriptionEntry to read cciDescr, the free-text label (such as a customer or circuit identifier) applied to a given circuit interface, and check cciStatus to confirm that description entry is active. This is useful when auditing a router with many ATM or Frame Relay circuits, where a missing or stale cciDescr value would reveal a circuit that was never properly documented after provisioning.
