6 rto recieving on vmanage network when failover tested

hi,

i have 2 10g uplinks in active to a vmanage, along with service and vmotion n/w.

when tested failover disabling one 10g port it worked fine without any drop when that port again made up gives me 6 rto.

i have service n/w on same vswitch and it does not recieve this rto .

i have not made any changes to vswitch since it is created recently.

pls advise if any config changes required.

thanks,

shrikant
