Description: Declares agent capability for Cisco Layer 4-7 service module redundancy 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.
What Is CISCO-L4L7MODULE-REDUNDANCY-CAPABILITY?
CISCO-L4L7MODULE-REDUNDANCY-CAPABILITY is a Cisco AGENT-CAPABILITIES module (not an object-defining MIB itself) that declares which parts of CISCO-L4L7-MODULE-REDUNDANCY-MIB are actually implemented on a given Cisco platform -- specifically the ACSW A3(1) software running on the ACE 4710 Application Control Engine Appliance. It supports the clrPeerConfigGroup, clrRedInfoGroup, and clrRedundancyStatsGroup object groups, but marks nearly every individual object (clrPeerInterface, clrPeerBackupInterface, clrPeerHeartBeatTime/Count, clrPeerRowStatus, clrRedundancyPriority, clrRedundancyStateChangeTime, and all clrHAStats*/clrLBStats* heartbeat and load-balancing counters) as not-implemented via VARIATION clauses. In practice this means the underlying redundancy MIB's peer configuration, high-availability heartbeat statistics, and load-balancing failover statistics are defined in the schema but not populated by the agent on this release. Capability MIBs like this one are consumed by NMS/MIB-compiler tooling to determine, ahead of polling, which OIDs will return real data versus noSuchObject on a specific device. It depends on CISCO-L4L7-MODULE-REDUNDANCY-MIB for the object definitions being described and on CISCO-SMI for the ciscoAgentCapability registration point, and administrators evaluating ACE 4710 monitoring coverage should consult the CISCO-L4L7MODULE-REDUNDANCY-CAPABILITY MIB before building redundancy-status dashboards.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-L4L7MODULE-REDUNDANCY-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 ACE 4710 Application Control Engine Appliance (ACSW A3(1))
Monitoring Examples
A monitoring tool checks this capabilities module before polling clrRedundancyPriority or clrHAStatsPeerDownEvents on an ACE 4710; because every VARIATION here marks those objects not-implemented, the tool would correctly skip them rather than treat a noSuchObject response as an outage indicator.
What Can Be Monitored
- which redundancy MIB object groups are supported
- peer interface/backup interface implementation status
- heartbeat timer/count implementation status
- HA statistics (missed heartbeats, peer up/down events) implementation status
- load-balancing statistics (sent/received packets, dropped entries) implementation status
