SG switches and Microsoft NLB

Hi,

does anyone know if the SG300 switches can be used with Microsoft NLB in Multicast mode?

I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?

So, any help or links to Cisco SG examples would be appreciated.

thanks

John

Re: SG switches and Microsoft NLB

I have not tested it yet. But I want to know this as well.

Keep in mind that you need to use the multicast MAC Address, not your normal MAC Address. It is bound to a multicast IP Address.

it's the binding of the multicast mac address to a "standard" IPV4 address that gives the problem. Works just fine on an IOS switch.
