major issue after upgrading to 5.0

[jamaster14]

i ran the upgrade from 3.0 to 5.0. all seem to have gone well. installed fine, rebooted. when it came back up in the alerts it said successfull upgraded to R5.

digital sets working, VM working. IP phones are not working, the phones on the display say "DHCP parse error" and the internet has come to a halt. when powering off the BCM50 the internet is fine.

not sure what the issue is, all settings seem fine. i havent installed any patches/updates. i am unable to find them. im on the ESL website, but cant locate them

Is the BCM 50 the DHCP server for this network? This sounds like an IP address clash to me or there are two DHCP servers issuing conflicting addresses.

im not sure if the BCM is not a DHCP server... in the DHCP settings in Element manager its set to "enable IP Phones only". it was set to this before the upgrade as well, as it asked you to verify this pre-upgrade...

I've removed the network connect to our BCM50, and instantly after doing so the IP Phones downloaded a new firmware and booted right up and work fine now.

im unsure as to what the issue is. some kind of IP conflict seems possible for sure, although im unsure why as nothing has changed settings wise that i know of????

Either way, the second i plug the BCM into the switch the interet slows down to a complete halt and is rendered uselss. any ideas on the next troubleshooting step here?

Something is confused here. The IP Phones must be accessing the BCM50 in order to download the firmware yet you say that the BCM50 is not connected to the network at that time.

I'm a little confused when you say you "removed the network connect to our BCM, and instatntly after so the IP phones downloaded a new firmware.....".

The BCM should only have one connection to the network for everything. If you disconnect the LAN connection, what are the IP phones talking to and what is the S1 server address in them and what default gateway address are they being given?

 

[ccarmock]

Are two of the BCM ports connected to the LAN maybe and you are removing one of them and things jump into life?

 

[jamaster14]

There are 3 connections from the BCM50

1 to a netgear switch(the one i removed that made the ip phones come to life)

1 to a DTI

1 to a station module?

the iphones are wired to a nortel 12 port PoE switch. default gateway is 192.168.1.125.

forgive the vague details, i was kind of thrown into administering all this stuff, with little backround on it. everything was working, exactly how it was currently wired prior to the upgrade.

i didnt touch anything until after the upgrade, which was removing the connection to the netgear switch.

Does the Nortel 12 port POE connect directly to the BCM50 or does it connect throught the netgear ?

Verify the BCM DHCP Server is set to DHCP-IP Phones Only and the address range does not conflict with the DHCP settings in the data DHCP server.

Also the Nortel POE Switch has Spanning Tree Protocol enabled on all ports. With this protocol it could take up to 30 seconds before the switch determines you are a host and not another switch to avoid switching loops.

There must be a phsyical connection between the PoE switch with the IP Phones and the BCM which is separate from your netgear or else they would not be able to download the firmware.

Typically you get that error when the DHCP server sends information back to the set that doesn't conform to the format the phone expects to see it in. It usually shows up when the sets are set to full DHCP and the DHCP server is a non-Nortel device, so in this case, I would start looking at where the sets are trying to get their info from.

Even though DHCP is set for ip phones only, make sure that the LAN port has DHCP turned on for it. I seem to recall reading something about that in the upgrade manual. What might be happening is it's turned off on the BCM port so your Netgear is providing info and the format is not correct.

Worth looking at.

Good Luck with it.

I guess we all forgot to ask........have you applied the latest service updates to that system?
