[nflug] Cisco Switch question on cloned NIC card

[David J. Andruczyk]

It sounds like they aren't configured for load balance,  but as
failover (hence the single mac for both ports)

How doe you have then comfigured for sure on the server side?

One way you can tell is to enable full logging/debugging on the switch
and pull the connections out one at a time and note the log entries
generated. (it'll also give you clues if you have failover configured
correctly), beware this isn't recommended practice on production
servers unless you have a downtime window that can be made use of.
