Avaya/Nortel has released a technical support bulletin documenting an issue that may arise regarding the NVRAM (flash memory) on the Ethernet Routing Switch 5500.

Apparently the auto-save feature may be exhausting the number of writes that the physical flash memory is capable of. If the switch is configured with MAC address security, a feature that could possibility be causing the auto-save feature to write the configuration hundreds if not thousands of times, the flash memory may surfer from extreme “memory wear” and cease functioning properly.

Thankfully there is a “second” NVRAM flash block available.

I would highly suggest that everyone review the bulletin for themselves.

It might be wise to disable the auto-save feature and have the technicians/engineers manually save any configuration changes when necessary (similar to how Cisco switches/routers work).

Cheers!
