High Availability

# High Availability

Device>Configure>High Availability

This feature is supported when CiscoView detects there is a redundancy supervisor in the Catalyst 6000 chassis and it is in standby mode.

High Availability Enable (sysHighAvailabilityEnable)

Indicates whether High System Availability feature is enabled or not. If this feature is enabled, the active supervisor's layer-2 protocol state will be synched to the standby supervisor module, thus maintaining an up-to-date protocol data on the standby supervisor whenever possible.

Note: This variable can be set to true only when Protocol Filtering is disabled on the switch and when Port 1/1 has port security disabled.

High Availability Version Enable (sysHighAvailabilityVersioningEnable)

Indicates whether support for supervisor software image versioning (i.e., the capability to run different images on the active and standby supervisors) for the High System Availability feature is enabled or not.

High Availability Oper Status (sysHighAvailabilityOperStatus)

Indicates the operational status of High System Availability feature. If the value of this object is notRunning(2), then the reason why this feature is actually not running is specified by the object sysHighAvailabilityNotRunningReason. If the value of this object is running(1), then the value of object sysHighAvailabilityOperReason is empty string.

High Availability Status cannot be set to true if dynamic vlan membership is enabled on any of the ports.

High Availability Not RunningReason (sysHighAvailabilityNotRunningReason)

Indicates the reason why High System Availability feature is not running when the value of sysHighAvailabilityOperStatus is notRunning(2). The value of this object is empty string when the value of sysHighAvailabilityOperStatus is running(1).
