Consider this as three test scenarios:
- Supervisor module failover/failback. Expected: Management access to be available after a few seconds disruption during the switch over.
- Management port connection failure on active supervisor module. Expected: Standby supervisor module will not take over. We won’t be able to access the switch any more. Review via console access to MDS 9000 supervisor will be required.
- Active supervisor module failure. Expected: Standby supervisor module automatically takes over with a few seconds disruption.
I am not convinced with the second test scenario on the MDS 9710 as we lose the management connection . I heard that multi chassis Ethernet switches provide redundancy on the second test scenario.
what you guys notice on the dual supervisor modules products?
