Description: Manages SONET interface configuration and performance monitoring on Cisco MGX 8200 WAN switch line cards.

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-MGX82XX-SONET-MIB?

CISCO-MGX82XX-SONET-MIB manages SONET interface configuration and Automatic Protection Switching (APS) on line cards within Cisco MGX 8200 series WAN switches. It belongs to the legacy carrier-grade WAN transport technology area, exposing objects for configuring working/protection line pairs, APS architecture mode, and switchover behavior between redundant SONET lines. Its data is centered on transmission-line fault and performance monitoring: apsSFBER and apsSDBER expose signal-fail and signal-degrade bit-error-rate thresholds, apsActiveLine reports which line is currently carrying traffic, and apsWtr tracks the wait-to-restore timer after a protection switch—together giving visibility into the physical health of the SONET transport and automatic failover behavior. This complements DS3/E3-focused sibling MIBs on the same MGX platform and depends on the general SONET/APS standards framework. It is deployed on Cisco MGX 8200 series switches providing carrier-grade SONET transport with 1+1 or similar protection schemes in service-provider backbone networks. Engineers can download the CISCO-MGX82XX-SONET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MGX82XX-SONET-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.

Supported Devices

  • Cisco MGX 8200 series WAN switch (SONET line cards)

Monitoring Examples

An operator monitors sonetApsConfigTable/sonetApsConfigEntry for apsActiveLine to confirm traffic is riding the expected working line, and watches apsSFBER/apsSDBER thresholds to catch early bit-error-rate degradation before a hard failure. If apsActiveLine unexpectedly switches to the protection line (apsProtectionSlot/apsProtectionLine) and apsWtr shows an active wait-to-restore timer, that signals a recent working-line fault that triggered automatic APS protection switching.

What Can Be Monitored

  • active vs. protection line status
  • signal-fail/signal-degrade BER thresholds
  • APS architecture mode and enable state
  • wait-to-restore timer
  • working/protection slot and line assignment
