Description: Declares agent capability statements for Cisco extended SONET MIB features on optical interface modules.

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 CISCO-SONET-EXT-CAPABILITY?

CISCO-SONET-EXT-CAPABILITY is an AGENT-CAPABILITIES conformance module declaring which objects of the companion CISCO-SONET-MIB a given Cisco optical/ATM switching module supports, covering platform variants such as the ATM Switch Service Module (AXSM), Enhanced AXSM (AXSM-E), Service Resource Module (SRM-E), and Voice Switch Service Module (VXSM). It belongs to the Cisco optical/SONET MIB family and defines no runtime data objects itself. It plays no direct monitoring role for hardware or software status; it exists to document per-module, per-firmware-revision support levels for SONET extension features. It is explicitly dependent on CISCO-SONET-MIB, the module whose object support it describes across multiple hardware revisions. It is used by SNMP management systems for capability discovery on Cisco MGX/BPX-class ATM/SONET switching platforms. Engineers can download the CISCO-SONET-EXT-CAPABILITY file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SONET-EXT-CAPABILITY. 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.

Supported Devices

  • Cisco MGX/BPX ATM switch service modules (AXSM, AXSM-E, SRM-E, VXSM)

Monitoring Examples

This is an AGENT-CAPABILITIES conformance module with no runtime data objects; it declares differing levels of CISCO-SONET-MIB support across AXSM, AXSM-E, SRM-E, and VXSM service modules rather than exposing monitorable data itself.
