3550 switch losing the configuration file.

In the last three weeks we have had three switches lose their configuration.

I had to reload the config to get working again. Has anyone experinenced this problem. When I have the problem I restart the switch and it asks if I want to do an initial configuration. I answer no and it puts me at the following prompt. switch>

Can you paste a sh version and what switch model is this ?

Hello,

this could be a memory problem; the running configuration is saved in DRAM, and the startup configuration is stored in the NVRAM section of flash memory. Does the switch actually crash ? If so, you might want to post the output of ´show stacks´, that could give an indication of what is going wrong.

Also make sure the configuration register settings are correct. When you do a ´show version´, at the bottom you should see the following:

Configuration register is 0x10F

Regards,

GP
