cbs350 switch with microsoft NLB mulitcast mode

nadm
Level 1
Level 1

has anyone configured a cbs350 switch stack to work with Microsoft NLB in multicast mode

I have found the the cbs350 does not allow adding the multicast mac address (complains illegal)  to the mac address-table and does not allow adding it as a static arp entry either.

instead i am going to try using 

ip multicast-routing igmp-proxy

ip igmp snooping vlan 50

ip igmp snooping vlan 50 querier

and

interface vlan 50

 bridge mulitcast address xxxxxxxx add te1/0/1-3,te2/0/1-3,Po2-4

the ports are also in a portchannels for LACP connections

years years back  i have come across this issue MS LB, now we no Longer uses (move to proper LB with latest models)

I am afraid Small business switch can do as Enterprise features never tested SMB switches othan Layer 2 function required.

some guide lines i have used with Cat 6K

may be try below (i am not sure that works, just want to refer)

thanks for the info,  i forgot there is a IGMP multicast mode for the NLB which supposedly doesn't need the static mac or arp entries, also the mac address starts with 01-00-5E-7F instead of 03-BF so hopefully just using ip igmp snooping for the vlan and querier will work
