Here’s the text from the 6.1.3 software release for the ERS 5000 series switch;

With MAC Security enabled, there were unwarranted writes to NVRAM without any configuration changes
(Q02126138)

Cheers!

In reply to Robert. If you are using MAC security then you'll want to read this post ASAP. You can actually exhausted the NVRAM flash memory given all the writes that can occur when you have MAC security enabled. I believe there is a new software release available that resolves this problem. Cheers!

Found the autosave command yesterday but did not have time to respond. Also found atleast on the 470 switches that this feature is either enabled or not, there is no option to adjust the intervals that the config is saved. And yes we have MAC port security enabled. Thank you for the information. We normally do all port adjustments manually anyway (locking the ports down after a device has been connected)so I will take a closer look at the characteristics of the MAC address port security command and see what my options are.
Thanks again!

Hi Robert,

Are you using MAC address security on your switch ports? There was a known issue with MAC address security causing an excessive number of configuration saves. In short the switches automatically save their configurations whenever any change is made. Do you have any management systems that have write SNMP access that could be making any changes?

You can disable that feature with the following command;

ER-470-48T(config)#no autosave enable

Just be aware that you will now need to manually save the configuration in either the CLI interface or JDM.

Good Luck!

Having issues with Nortel switches constantly saving their configs to NVRAM. It is sending trap and SNMP info to the network managment software/server every 30 seconds.(Way too much wasted resources) I can not seem to locate any information in the CLI about this feature. I would like to be able to adjust the time interval that the configuration is being saved to NVRAM, or to just disable this feature.
Does anyone have info in regards to this issue.
Happening on 470’s, 4500 series and 5500 series switches.

Hi Alan,

I’m sorry to say that I don’t really have any experience with the Avaya handsets. I couldn’t really tell you what the problem might be with that handset.

Sorry I can’t be of more help.
Good Luck!

Hi Michael

Are you able to point me in the direction of some sound support of Avaya VOIP phones?

I have a 9640, which is brand new but won’t boot. I just get a single flash (on / off) of the red light on the phone when connected to a known voice socket, with no display function whatsoever.

Is there anything I can do to re-flash the firmware, or should I pay the £70 our phone support company wants to repair it?

Have found very little on the we which covers a non-booting Avaya phone.

Regards

Alan

Hi Olivier,

I could be wrong but I believe the reload command is suppose to disable the auto-save feature when invoked.

5520-48T-PWR# reload minutes-to-wait 5
Reload (y/n) ? y

Warning the switch/stack has been set to reload in 5 minutes
Current configuration has NOT been saved. Configurations must be explicitly saved

I’ll test it and let you know what I find.

Thanks for the comment!

Hello !
Thanks for this good tip ! But I think you need to do this before in case where it is set :

ERS5520-PWR# configure terminal
ERS5520-PWR#(config) no autosave enable
ERS5520-PWR#(config) exit

If not, you risk to boot with the bad config saved automatically.
