I have the exact problem metionned into this thread, but between two CS1000 signaling servers. Each one is connected to a Brocade SuperX router, on the same vlan but the TPS election, an UPD broadcast on port 16550 is not passing to the other side. We put the both sig servers on the same superX, same network module, same vlan and it dosen't work either. Moving the both sig to a Nortel switch for testing solve the problem. I'm version 7.1.00a of the SuperX. We upgrade form 5.1.00c in August, but the problem seems to the there since November only...

Anyone had some news from foundry/brocade?

We had an issue with our Foundry too - can't recall right now if it was SuperX or RX-4 but we upgraded and our CS1000S started freaking out so we rolled back. Good luck getting info back about it.

The problem is solved, here is the situation :


The firmware 7.1.00a have a bug fixed in version 7.2.00a (bug # 108591) that when you have a vlan with ip helpers configured, the local brocast into this vlan dosen't work in some situation...and the UPD broadcast on port 16550 for the TPS election seems to be one of the situations..So removing the helpers or upgrade to version 7.2.00a are the available fix.


Regards.

* for you!! I passed this on to our NetEng and I can post when this is completed (if they decide to keep the SuperX - we have a RX-4 that was going to go in instead) so your solution might convince them to keep it and use the RX-4 elsewhere!!!

Thanks again for the post!

Well they are still getting rid of the SuperX - I am sure it would have fixed our issue. Wonder how many others have Foundry - we did know it was a IOS upgrade issue but didn't know exactly what was causing the issue so thanks for the vlan ip helper explanation.

No problems! But a quick way to test it before getting rid of the SuperX is just doing a no ip-helper command on the vlan...
