[AusNOG] Preparing 100s of routers for resale

[Thomas Sulkiewicz]

I agree,

I think the time it would take to plug in a network cable you might just want to plug in the console cable instead. Too many variables if you actually have to log into the box, you're going to spend more time trying to figure out the login and looking for the device on the network then you would just blowing it away via rommon/confreg.

Depends if you already know the IP's and credentials of these devices, or can knock up a script to guess the IP, and credentials from a set list,.  If not I think it would be more practical to script a console boot/break/password recovery and use a terminal server to scale it if needs be.

Also you need to weigh up the time it takes to get a junior to do this manually against the value of spending time attempting to automate it.

Might warrant a different approach if you had a few thousand to do rather than a few hundred...

I'd be trying to do it via network rather than serial
just because by serial your only going to be able to do a few at a time and the boot time etc for these things can be excessive.

Are they all using the same (or only a couple of different) images? If so I'd suggest
replacing all the compact flash cards, then booting each one and grabbing the appropriate
image from a tftp server. You can then reboot it and clear the config using password
recovery mode if necessary.

I don't have access to these devices yet, but from previous experience it would likely be a single basic 12.4 image with just vlan/port/trunk port/snmp configs

Do they have SSH?
Do they have a similar auth config user/password?

does the ssh info get stored elsewhere?


Thanks all for the suggestions. Seems automating a serial console session will be the best option for this task. I'll just script a Linux netbook so I can churn through them.
