Vishal,
If I read you correctly:
[sw3-port10]---(po)----[sw1-port23]---(po)----[sw2-port23]
| \ ____________________ / |
| ----------------------\------------/ |
(host-B) ------------/ \---------- (host-A)
If these are virtual machines, and you are not using Stack-wise switches,
and or VSS or Nexus VPC switches you cannot do Ether-channels between two
separate switches with separate control planes and a single machine. You
however, can do nic teaming which will keep the virtual machine with two
separate nics connected to separate switches, but one interface will be
active and the second will be inactive, and the inactive nic will only
forward traffic when the first nic fails.
Your recommendations would be to configure nic teaming, if you need more
bandwidth you can port-channel to the same switch but this reduces your
redundancy. You are limited based on the switching equipment you have in
your chassis or network.
Thanks,
Joe
