As long as they make sure the vSwitch does not alternate between physical links for the same guest you're fine. Our trunks generally look like this (from a 3560X): interface GigabitEthernet0/3 description (Unused VMware port) switchport trunk encapsulation dot1q switchport trunk allowed vlan 100-299,800-899 switchport mode trunk switchport nonegotiate link state group 1 downstream storm-control broadcast level pps 250 spanning-tree portfast trunk spanning-tree bpduguard enable ! If most of your traffic is to/from somewhere beyond the first set of switches, i.e. you don't expect a lot of communication between guests on VMware servers connected to the same switches, you should probably consider not stacking the 3750, should you choose to use those. Look in the archives for possible reasons for this. -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
