Description
This mib defines the SNMP objects to report the status of High Availability (HA) functionality in Cisco network management appliance devices. The HA functinality is achieved via the redundancy of network management appliance devices. An network management appliance is a device which combines hardware and software to provide specific network management services. Cisco WLSE, Wireless Service Engine (WLSE) is such an appliance. The High Availability is achieved via redundancy of appliances. This redundancy scheme is designed to support hardware or software failure of the appliances in a non- disruptive manner. Redundancy is achieved by configuring a cluster of two appliances with one common virtual IP address. The data is mirrored from the active appliance to the standby appliance at regular intervals. One of the appliances is in active mode, performing all normal functions. The other appliance is in warm standby mode; that is, the appliance is up but no application services are running. Both the active and standby appliances have their own IP addresses. The active appliance also owns the virtual IP address to which all the service requests are made. The active appliance and standby appliance periodically poll each other. If the standby appliance cannot reach the active appliance, it will become the active appliance. This is called a switchover event. The switchover can be caused by other causes, for example, via user commands. Both the active and standby appliances should implement this MIB and report any exceptions caused by switchover events.

Textual conventions
| Name | OID | Syntax | Access | Status |
|---|---|---|---|---|
| CarRedundancyState TEXTUAL-CONVENTION States of the HA redundancy: notConfigured - The appliance is not configured for redundancy. starting - The appliance is configured for redundancy and is initializing. This state could apply to both active and standby appliances. active - The appliance is the active appliance. preStandby - The appliance is configured to be standby and is attempting to restore data from the active appliance and is not yet in the standby mode. standby - The appliance is warm standby mode. activeLostStandby - The active appliance is not getting any response from the standby appliance. activeLostNetwork - The active appliance is not getting any response from the standby appliance or from the default gateway. There is possibly network issue. standbyLostNetwork - The standby appliance is not getting any response from the active appliance or from the default gateway. There is possibly network issue. | current | |||
| CarSwitchOverReason TEXTUAL-CONVENTION Cause of HA switchover event. lossConnWithActive - Switchover is caused by loss of connectivity to active appliance. forcedSwitchOver - Switchover is caused by user command. unknown - Unknown reason. | current |
