I currently have 1 nortel 5510 switch connected via ether channel to a 4948 which is then connected to another Nortel 470-48T via a single 1Gb uplink.
Attached to the 5510 is a server that sends multicast traffic for an application and a server connected to the 470 that needs to receive the multicast traffic. I enabled IGMP on all my vlans (the two servers reside in the same vlan) last week and now the client is not receiving that multicast traffic. I have configured vlan 1 on my 4948 to be a member of the multicast group 234.5.6.7.
I can see the multicast traffic coming out of the 5510 switch if I mirror the uplink ports, but if I mirror the ports on the 4948 side, I dont see the traffic actually coming into the switch.
Can anyone point me in the right direction here?
Thank you in advance!
James
