I have this wierd issue going on, We have this Unix HACMP clusters where two ports in one server connected to two different switches but report the same MAC address on their port and as result I get the error
Sep 17 11:28:29.321 EST: %C4K_EBM-4-HOSTFLAPPING: Host 00:11:25:C0:86:3D in vlan 10 is flapping between port Po27 and port Gi4/34
First I though if they were on same switch I can configure EtherChannel but unfortunately for redundancy purpose they can't be in one switch and nor they can use different MAC address due to hacmp requirement. Can someone sugest a solution to this situation.
