Chapter 17 Configuring High Availability
Synchronizing Supervisor Modules
The standby supervisor module automatically synchronizes its image with the running image on the
active supervisor module.
See the “Replacing Modules” section on page 15-17.
The following conditions identify when automatic synchronization is possible:
• If the internal state of one supervisor module is Active with HA standby and the other supervisor
module is HA-standby, the switch is operationally HA and can do automatic synchronization.
• If the internal state of one of the supervisor modules is none, the switch cannot do automatic
synchronization.
Table 17-1 lists the possible values for the redundancy states.
Table 17-2 lists the possible values for the supervisor module states.
Table 17-3 lists the possible values for the internal redundancy states.
Table 17-1 Redundancy States
State Description
Not present The supervisor module is not present or is not plugged into the chassis.
Initializing The diagnostics have passed and the configuration is being downloaded.
Active The active supervisor module and the switch is ready to be configured.
Standby A switchover is possible.
Failed The switch detects a supervisor module failure on initialization and automatically
attempts to power-cycle the module three (3) times. After the third attempt it
continues to display a failed state.
Offline The supervisor module is intentionally shut down for debugging purposes.
At BIOS The switch has established connection with the supervisor and the supervisor
module is performing diagnostics.
Unknown The switch is in an invalid state. If it persists, call TAC.
Table 17-2 Supervisor States
State Description
Active The active supervisor module in the switch is ready to be configured.
HA standby A switchover is possible.
Offline The switch is intentionally shut down for debugging purposes.
Unknown The switch is in an invalid state and requires a support call to TAC.
Table 17-3 Internal States
State Description
HA standby The HA switchover mechanism in the standby supervisor module is
enabled (see the “HA Switchover Characteristics” section on page 17-2).
Active with no standby A switchover is possible.
