CISCO-CAS-IF-EXT-CAPABILITY

Description: Declares SNMP agent capabilities for the extended Cisco CAS interface MIB.

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.

CISCO-CAS-IF-EXT-CAPABILITY is an AGENT-CAPABILITIES module documenting which objects of the extended CAS interface MIB (CISCO-CAS-IF-EXT-MIB) a given Cisco agent implementation supports. Like other capability modules it defines no managed objects of its own and exposes no directly pollable monitoring data. Its indirect purpose is to support correct interpretation of extended Channel Associated Signaling interface status and configuration objects, aiding tooling that manages CAS trunks on Cisco voice gateways. It is entirely dependent on CISCO-CAS-IF-EXT-MIB for the object definitions it references. It is used by MIB compilers and NMS conformance checks rather than being polled directly for device health, with the CISCO-CAS-IF-EXT-CAPABILITY MIB serving as the definitive conformance reference for that tooling.

An NMS validates against this capability module to confirm which extended CAS interface objects a specific Cisco access gateway image implements before enabling automated polling of those extended attributes. Because it contains no sample objects, all of its content is capability-statement metadata pointing back at CISCO-CAS-IF-EXT-MIB. This check would typically be performed once during device onboarding to a monitoring platform to avoid polling unsupported OIDs and generating spurious no-such-object errors.
