I have a situation that has been driving me crazy. I would appreciate any advice.
In a few locations we are running old Nortel 450-24T's (with 1.48 / 18.104.22.168) mixed with C2950-24's (with 12.1.22.EA8a).
I'm having a hard time getting Ghosting/ZenImaging to work smoothly on the network.
IGMP Snooping is enabled on both, however the Nortel only supports v1 and v2. The cisco defaults to 2 but supports 1 and 3 (somewhat). I have issues with machines not wanting to join the multicast session. I can issue the "IP IGMP Snooping Group" command and sometimes I see the groups joining and sometimes there's nothing.
Is there a known issue with IGMP between the two products? If there's any Nortel savy people around can you tell me something that's worked for you?
I did read on a newsgroup post somewhere that under the IGMP settings to disable "Proxy" as it causes issues. I did this and it did seem to clean things up somewhat.
I've been trying to read up on igmp snooping and multicasting but most articles keep talking about setups where your using it across wan/routers etc. We're just doing local stuff.
In the locations that I've been able to replace everything with Cisco I've simply enabled the default IGMP Snooping settings and I can image a 100 computers with no problems.
Thanks for any suggestions.
