NIC Team fails in ESXi 5.5

Hi All,

i have 3 node cluster running ESXi 5.5.

i have network setup as given below.  i have 4 NICs per server.  All 4 ports are trunk.

Created two switches - vSwithch0 with 2 NICs (Management Console and vMotion) and vSwitch1 with 2 NICs (Both nic will be used for VM's as per their respective Production VLAN)

management network chosen vmnic0 as active/vmnic 1 as standby and for vMotion network vmnic1 active/vmnic0 standby

and for vSwitch1 - i added vmnic2 and vmnic3 as active/active

So summary including sample IPs.

vSwitch0 - management network(removed check mark from vmotion traffic) - e.g 10.34.45.x (say vlan 45)- vmnic0 active/vmnic1 standby - physical switch port trunk - management network allowed VLANS (all 4095).

               - vMotion network(removed check mark from management traffic) - private vlan e.g 192.168.12.x (say vlan 12) - vmnic1 active/vmnic0 standby - physical switch port trunk- vmotion network allowed VLANS (all 4095)

vSwitch1 is working fine. (multiple port groups in seperate VLANS ). both vmnic2/3 are active/active and ports trunk. (no probs)

But :

above setup is working fine as long as each nic is associated to its own network(i.e vmnic0 to management network and vmnic 1 to vmotion). NOW  i am doing failover testing.

in order to test failover testing, i am not removing cable from vmnic0. i am just moving vmnic0 to unused adapter and moving vmnic1 to active adapter for management network under vswitch0 on one of the host. Ping to 10.34.45.x is breaking. so it is failed. i am unable to ping over vmnic1. and ESX automatically reverting changes back to original. i.e making vmnic0 as active and vmnic1 as standby and it starts working again with an error in VCENTER.

is there any wrong configuration above. speciallly IP level. i created vmnic0 and vmnic1 as trunk from physical switch level. so that if vmnic 0 fails, vmnic1 reaches another VLAN i.e managment network VLAN. but it is not working.

Note: below graphs are taken from another thread but i have same setup.

Management Port Group with vmnic0=Active , vmnic1=standby

vMotion Port Group with vmnic0=standby and vmnic1=active

Project VM's with their respective VLAN's both the vmnic2=active and vmnic3=active is active.

.

Thanks
