Query on VSS and vPC

[vijay kumar]

Hi all ,

What is the  difference between VSS and vPC . Can we consider VSS is for 4500/6500 platform and vpc for nexus platform ? Does it provide the same mechanism?

Thanks,

Regards,

Vijay.

Basically, VSS allows two physical 6500's to be managed & function as a single logical switch.  vPC, or virtual port channel, allows a single logical port channel to be presented to an end device (though each half of the virtual port channel is configured and managed by two logically distinct nexus switches).

Here are some links to expand further:
