HA Redundancy States
•
If the internal state of one supervisor module is Active with HA standby and of 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 7-1 lists the possible values for the redundancy states.
Table 7-2 lists the possible values for the Supervisor state.
Table 7-3 lists the possible values for the internal redundancy state of the supervisor modules.
Table 7-1 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 This module is the active supervisor module and
the switch is ready to be configured.
Standby This state indicate that 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 switch is intentionally shut down for
debugging purposes.
At BIOS The module 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.

State Description
Active This module is the active supervisor module and
the switch is ready to be configured.
HA standby This state indicate that 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
