Would anyone let me know what is "SW" field is and what it is used for . To me a single VRRP MAC has got multiple SW filed in it . is that a problem ?

Thanks and regards .

Nope, concentrate on Index, BD and FE.

FE is Forwarding Engine

BD is internal vlan

and index is LTL index >> to map it to physical interface use "sh system internal pixm info ltl_index". 

If it is a VRRP mac it should point to SUP.
