We have a mulcitast server that is firewalled but does not pass multicast traffic from the firewall to the n5k switch. It only passes the mulitcast traffic when we take the multicast server off the firewall. I'm presuming this is so becasue igmp/pim is not enabled on that port-channel trunk link between the fw and n5k switch. How do I enable it?
When you say if you take it off the fw it works. First, did you checked that igmp is enabled on the vlan that interconnects fw and your switch?
Have you validated that multicast traffic passes through firewall without being blocked? What type of firewall do you have? You can configure the firewall to connect to your rp outside of the firewall and then internal will be able to get this multicast traffic.

It's a palo alto firewall. When issuing that command, I don't see anything for that vlan. I think the reason I don't see anything is because that VLAN is not an svi defined vlan on that switch. the scope/addresses is defined on that fw.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
