Can router loose config?

We have to store about 100 remote site routers over the winter period. They are a mixture of 800 and 1700 routers.

We have concerns about them loosing their config as they will be powered off until the spring. Obviously this would cause us major problems if we had to drop the config again as they will stay at the remote site where there are no support staff. We support them remotely via telnet.

My understanding is that the config like the IOS image is stored in flash which is an EEPROM technology opposed to NVRAM which requires a power source.

Am I correct in thinking that the the routers can be powered off for several months without loosing their config?

Many thanks in advance

Re: Can router loose config?

hi

make your self double sure about the modifications being saved (running config into startup) which will prevent mismatch in the config.

otherwise you dont need to worry about switching off the routers for months .

Also have a cross chek on ur configuration register values which should be 0x2102 in all the routers.

you can check it using show version..

do change it to the above value if its something else on ur routers.

Hi

You might wanna use this command in the enable mode,before powering off your routers.

This will save your current config and you can keep your routers powered off,for several months.
