yes, i forgot to include the VSS/SMLT extensions (we use cisco switches).

although rereading the original it sounds like they just want redundant links versus increased bandwidth and high availability at the same time.

the standard vif with a vif favor will accomplish this and is quite simple. vif favor will also return the connection to the primary switch when it's connection is restored rather than remain on the standby switch.

if this is a redundant setup why would you not configure your switches with 802.3ad link aggregation and configure a vif on your filer with those two interfaces?

I believe for 802.3ad both connections would have to go to the same physical switch.
