I have an ESX server with two NIC's connected to two seperate 2960 switches (for reducnecy presumably) The two 2960 have a trunk to the core switch 4507. In the syslog I see the following message:Host 00:50:56:47:9B:88 in vlan 104 is flapping between port Gi7/4 and port Gi7/6
How can i stop this 'flapping' occuring?
The server NIC teaming needs to be set for fault tolerant, meaning only one active with the other standby. If they are set for load balancing the NICs need to be connected to the same switch on an etherchannel.
