CAUTION:
Active and Standby Roles
Table 10-1 shows possible supervisor configurations and, for each
configuration, which supervisor is active and which is standby.
* Note: If the standby supervisor becomes active, it assumes the IP and
MAC addresses of the previously active supervisor.
* Note: When a standby supervisor is installed in the switch there is a
45-second wait period before the standby supervisor is fully
initialized.
Do not remove the standby supervisor module during initialization.
Table 10-1. Supervisor Module Configurations
Configuration Active and Standby Role
One supervisor in slot 1 The slot 1 supervisor module is active.
If a supervisor module is inserted into slot 2, the slot
1 supervisor module remains active and sends health
reports to the standby supervisor in slot 2.
One Supervisor module
in slot 2 The slot 2 supervisor module is active.
If a supervisor module is inserted into slot 1, the slot
2 supervisor module remains active and sends health
reports to the standby supervisor in slot 1.
If the slot 2 supervisor is removed, reset, or fails, or if
the switch is reset, the slot 1 supervisor becomes the
active supervisor, and the slot 2 supervisor becomes
the standby. The slot 1 supervisor then sends health
reports to the slot 2 standby supervisor.
Supervisor modules in
slot 1 and slot 2 The slot 1 supervisor module is active and sends
health reports to the standby supervisor in slot 2.
If the slot 1 supervisor module is removed, reset, or
fails, the slot 2 supervisor becomes the active
supervisor. If you then replace the slot 1 supervisor, it
remains the standby supervisor and receives health
reports from the active supervisor in slot 2.
If the slot 2 supervisor is removed, reset, or fails, or if
the switch is reset, the slot 1 supervisor becomes the
active supervisor, and the slot 2 supervisor becomes
the standby. The slot 1 supervisor then sends health
reports to the slot 2 standby supervisor.
Note:
If the switch is reset, slot 1 supervisor is the
active supervisor, unless it has failed.
