Hey Buddy.
Not sure if these are equivalent commands, but the set up below is how I got it working.
Igmp filter-unkown-multicast
Igmp fastlearn *Port-Range* (eg. 1/1-1/46)
Igmp lookup-mode ip
Jumbo ip-mtu 9000
VLAN 691
Name “What Ever”
Tagged *Trunk Port*
No ip address
Ip igmp
Jumbo
Exit
Obviously the running config on the switch has a lot more in it, these are the bits I figured out to get the multi cast devices working.
The Clock source browser bit just syncs the switch clock with your web browser, since we use ntp this could just be omitted.
Reading through the documentation on both switches trying to learn about Multicast, I think I am correct in saying the “immediate leave” bit on the Cisco is the same as “Fastlearn” on the Aruba. It sounded similar anyway.
I hope this helps, if you have any other questions, give us a shout.
If anyone thinks I’m wrong and wants to shoot me down, please do. I’d prefer to get it right and in no way consider myself an expert on the subject.
