We are debating whether to enable link state tracking for servers with teamed NIC to detect upstream uplink failures between switches.
If the switch the server with teamed NIC is directly connected to have multiple uplinks to different distribution switches in port-channel, the question we need answer to "Is link state tracking required"? Personally I don’t think link state tracking is needed in my scenarios with multiple redundant uplinks.
Any comment is welcome.

Francisco,
If you do NIC teaming on your server (LACP) and connect each NIC to a different stacked 3750, you now have NIC redundancy and switch redundancy. I tested this with 6500 VSS and it works really well. When we pulled one link from the switch. The traffic used the other NIC going to the other switch without loosing a ping. You do not need any link state tracking at all.

Hey Reza,
Thanks for your comment. Appreciate it.
Yes i think also switch redundancy is enough.
