[c-nsp] Nexus and Microsoft Unicast NLB

[James Slepicka (c-nsp)]

I have NLB Unicast clusters running on FEXs hanging off of Nexus 5548s.   In unicast mode, there's no need to define static mac entries since traffic will be flooded.  I simply stick the clusters in dedicated VLANs.

Is anybody else connecting Microsoft NLB unicast "cluster" servers to a Cisco Nexus switch? Cisco TAC is telling me that the Nexus 5010 running 5.0(3)N1(1b) won't support NLB unicast mode, and I should just move to NLB Multicast or stick the NLB servers in their own VLAN.

P1-N5K-1(config)# mac address-table static 02cf.c0b8.d46c vlan 100 interface ethernet 100/1/44 ethernet 101/1/44
ERROR: invalid number of interfaces specified
