Passport config saving problem
« on: July 14, 2014, 09:06:44 AM »
Hello,
we have 2 Passports 8600 (ERS-8610; SW Rel. 7.1.1.0; 2 CPU-Cards in ha-mode) connected by an IST. One of the two devices has got a problem. Since today we cannot access the device by WEB-Access. Furthermore we cannot save the config file. The CPU Utilization shows 13 % which should be normal. The DRAM Used shows 37% and the DRAM Free 329605 K.
A few weeks ago we had a similar problem with WEB-Access. A reboot of the CPU-Card helped (Switchover to the Second CPU). This time however we have these problems with the config file.
Has anyone an idea how to handle this problem?
Thank you in advance!

something similar has happened to me before.
there were duplicate RSMLT addresses within the network and performing a "save con" would make the CPU spike to 100%.  I would also get locked out of the web-interface.

I would check the logs to see if something is going wrong within the network or switch.

SHOW>SYS> LOG FILE TAIL

Look for spanning tree changes, duplicate IPs addres or VRRP failovers, or failed SNMP requests

Hello,
Thanks you for your reply Paul!
I just had a careful look at the log file. There were no special indications concerning  spanning tree, duplicate IP adresses or VRRP failovers but there were massive SNMP requests during a short time (1 hour). Could this have such an effect? The SNMP reqests stopped but the problems are still present. Could it be useful to boot the cpu card although the cpu utilization is 13 %. The last time we had a cpu Utilization of 80 %.

Thank you!

Yes, SNMP processes work in software and CPU, not in hardware.

I wouldn't reboot the switch. it won't solve the problem.
What is the specific issue you have with saving the config? 

what you need to do is check out the logs when the CPU does spike to 80%.

When I type the command "save config" there is no reply. The telnet session seems to get stuck. I opened another telnet session during the stuck session without any problems.

I would try this..
setup a workstation on the local console and check the Logs and CPU. Show sys Perf.

then start a telnet do the save con command. 

Check on the local console is the save config command is what triggers the high CPU and then double check the logs.

I just connected to the Passport via console and via telnet and checked the Performence on the telnet session by saving the config via telnet. "Show sys perf" on the console did not show higher CPU-Utilization (13%). Maybe there is a hardware problem as the Master-CPU LED did not blink.

setup a syslog server and keep watching the logs. 

what you are describing is not a hardware issue as a hardware issues tend not be intermittent. 

I would open a ticket with Avaya support.

I've had the problem with being unable to save before.  There is also a solution out where:
"The ERS switch can get into a state where it can no longer show nor save the configuration."  Fix is to reboot or have Avaya unlock the configuration semaphore.  Soution is SOLN189763.

Hello,

we just switched over to the other CPU-Card and the problems were gone. I think if these appear again we have to upgrade our Image software before we can open a ticket with Avaya support.

Thanks to all for your help!
