What Is CM-REDUNDANCY-MIB?
CM-REDUNDANCY-MIB is a MIB for the ADVA/Ceragon FSP150CM product line (Carrier Ethernet/microwave transport platform) covering hardware redundancy group management, the pairing of an active and standby control/line card and the automatic failover between them. It exposes a redundancy group table describing group type, whether synchronization between active and standby cards is enabled, which card is currently active versus standby, the operational state of each, and the time and reason for the most recent switchover. This is directly a hardware-health and fault MIB: it lets an admin confirm which physical card is active, whether the standby card is healthy and in sync, and investigate the cause of a recent failover, key data for verifying the resiliency of the platform's card redundancy scheme. It defines its own notification group (cmRedundancyNotifications) for switchover events, alongside the FSP150CM's broader entity/card management model that these group/card indexes reference. It is deployed on ADVA/Ceragon FSP150CM microwave/Carrier Ethernet transport platforms in telecom transport networks where card-level redundancy is required for high availability. Network engineers evaluating or troubleshooting this functionality can download the CM-REDUNDANCY-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CM-REDUNDANCY-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.
What Can Be Monitored
- active vs standby card identity
- active/standby card operational state
- synchronization enabled status
- last switchover time
- last switchover reason
- redundancy group type
Supported Devices
- ADVA/Ceragon FSP150CM microwave/Carrier Ethernet transport platform
Monitoring Examples
An admin would poll cmRedundancyGroupTable/cmRedundancyGroupEntry indexed by cmRedundancyGroupIndex to read cmRedundancyGroupActiveCard/cmRedundancyGroupActiveCardState against cmRedundancyGroupStandbyCard/cmRedundancyGroupStandbyCardState, confirming the standby card is in a healthy ready state and cmRedundancyGroupSyncEnabled is true. A recent, unexpected cmRedundancyGroupLastSwitchOverTime with a fault-related cmRedundancyGroupLastSwitchOverReason would indicate the active card failed and the group failed over to standby.
