Alcatel Unleashed

Hello,

I am wondering if anyone here knows why?
When i change one networkcard or one routerport in my system OXE from auto negotiation to 100MB-full the setting makes the complete network go into a reset. All phones reboot and server connections drop.
I found out that when the system has a standard networkcard config it is in auto mode and sometimes switches to 10MB-half duplex. The calls that come in or go out are very noisy. A good conversation is not possible.
So i changed one of the first switchports to 100MB-full after i found out it was on auto in the worst setting 10MB-half.
Normaly this should have no impact, but when i changed it to 100MB-full i got a call that the system went down for a few seconds with the message that all phones rebooted and CCS dropped the connection also.
When i was working on one of the GA's i also found a auto setting on 10MB-half, a module was not responding, so maybe the network setting problem, so i changed that to 100MB-full, again my phone was ringing, again a reboot of all the phones, CCS dropped the connection also.
I know that unix (servers) have a freeze (timeout) when a system has to failover, but this takes a longer periode then a few seconds of fall out when switching to the failover. Could this be the same issue?
I have a failover, but a port setting should not make the system reboot all the phones and kill all server connections like CCS.

I changed all switches and routers to 100MB-full and it works oke and no more loud noises on the phone lines.

Does anyone knows why the reset/reboot happens?

Best regards!

Hi ,

I saw that in the past.
This is what happened in my case, let me know if this is your case too:
We changed the port negociation where the CPU was connected and where the INTIP boards where connected.
We noticed that somehow as a protection, if the boards receive too much broadcast, they would do a quick "off line / on line" cycle.
We worked on Alcatel and Cisco switch who did NOT have FAST ETHERNET activated. Therefore, it took everytime about 50 seconds for the port to come back up. During this time, the UDP_LOST is reached, and all the phones on the network rebooted.

You need to be sure that this feature is turned on on your data switch.
Also, regarding the negotiation, you want to be sure that it's the same in both ends.
You can't have 1 side in auto negotiation, and the other one setup hard 10/100 half/full duplex.

Hello Frank!

Thanks for your answer!
In my case, we had a worse case of interference on the phonelines.
We checked the network and found out that the network was on auto negotiation and talking on 10MB half duplex.
We changed the network settings to 100MB full duplex, all the phones went into a reboot.
This was the first time i had the problem, call's lost and waiting que was gone.
Normaly changing settings would not be an issue.

A few weeks ago i had troubles in a rack, it was down and not talking anymore, we checked the settings and found again a 10MB half setting on the MEX.
So could this be the trouble? So i changed it to 100MB full duplex and my phone was ringing of the hook.. there was a reboot.
In this case i think we had the same problem.
I would like to know if i can shut down the security and chack and when needed change settings in the system because i now think i need to check all the network ports. I have seen a network overflow message on my CCS.
The system works normaly on 25% of the 100% available capacity, so the system can handle much more call's.

If there is a setting to shut down the security in stead of rebooting all phones and getting a lot of call's myself i would like to now how :p

Thanks!

Well..

Can you get into the phone, and look at the log of why it rebooted ?

Dear Frank,

I looked in the phones, but no usefull info found..
The system makes the phones reboot when a blip appears on one of the network connections.
The security is very sharp tuned.
This happend recently again and i was not working on the system.
No one else was working on it either.
I think a possible power peak on a switch triggered a reboot of the phones, but no errors found in switches, all up and running oke.
I hope that there is a setting to reduce the reboot's.

Best regards,
