Vif creation and bus redundancy

[CLOUDMINER]

I am attempting to create a vif on a FAS2040.  There are 4 ethernet ports e0a,e0b,e0c and e0d.

If I create the vif across e0a and e0b, and the bus that services those ports fails, will I lose both e0a and e0b?

Should I create the vif across e0a and e0c?  Or are they all sharing the same bus anyway?

You should use e0a + e0c for a channel and e0b + e0d for the other channel.

Yes e0a and e0b run on the same ASIC (as well as e0b+e0d).
