    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."

                              data from the active appliance and is not
