Supervisor fail over

Unanswered Question
Feb 6th, 2007

We have a MDS 9513 switch and are testing the supervisor fail over.

We tried to disconnect cable to the mgmt port of the active suppervisor. Waited 5 mins and no failover, no Mgmt access

Can any one tell me in what Scenarios the Suppervisor would fail over?


I have this problem too.

The sup wont fail just for a mgt network failure.

The sup will fail when there is a critical hardware/software error on the sup which prevents the sup from working.

If you are keen, you can test failover by ripping the sup out :)

The supervisors will not fail over b/c the mgmt interface is down. Supervisors failover in case of upgrade, process crashing where process cannot restart, or manual failover. You can force a failover with a system switchover command.
