Not so sure about that. I couldn't find any messages about the loss of our F400 on this vswitch (but it could have happened some time ago).
q vswitch teevsw0 VSWITCH SYSTEM TEEVSW0 Type: VSWITCH Connected: 2 Maxconn: INFINITE PERSISTENT RESTRICTED NONROUTER Accounting: OFF VLAN Aware Default VLAN: 0755 Default Porttype: Access GVRP: Enabled Native VLAN: 0755 VLAN Counters: OFF MAC address: 02-00-0E-00-00-01 State: Ready IPTimeout: 5 QueueStorage: 8 RDEV: F600.P00 VDEV: F600 Controller: DTCVSW1 RDEV: F400.P00 VDEV: F400 Controller: DTCVSW2 BACKUP It still shows as the backup when I know for a fact it is down (the cisco viewpoint shows it down ). I'd like to be able to monitor them from VM as well (that's what I should have said - it does sound like the cisco side is aware) - so I guess I have to look into the SNMP monitoring David suggested.

How do you know they haven't lost connectivity and won't be there when you need it? (asking because, well, yeah, that can happen :) Marcy "This message may contain confidential and/or privileged information.
