Re: Microsoft Unicast NLB with cisco devices

The problem is when doing the microsoft NLB (whatever the mode unicast, or
multicast) due to the bogus mac address, the switch flooding the traffic to
all the ports. looks like unicast broadcasting. If you read the cisco link
it will clearly explain about the issue.

Yes, I know Unicast is the default configuration. but cisco provided
solution for multicast, moreover I am trying the same solution for unicast,
but it seems not possible to add a same static mac address for two or more
interfaces.
but it works in 3750.
