Our switch displaying the following when turning on terminal monitor (This is just a few of the offending ports)
46w3d: %C4K_EBM-4-HOSTFLAPPING: Host 00:50:56:98:48:86 in vlan 10 is flapping between port Gi3/8 and port Gi2/26

Ports are configured as below and all relate to our VMware host NICs.

switchport trunk encapsulation dot1q
switchport trunk allowed vlan 10-13,30,50
switchport mode trunk
end
Our vSwitch is setup with Link Staus only for failover detection and LB is using Route based on IP hash.
From what I understand this is causing latency on our network and possibly STP issues? Has anyone got a resolution for this?
Thanks
