My new Cisco 678 came on Thursday. I was out Thursday night, and Friday we had some friends over, so I didn’t get a chance to do anything with it until today. So today I plugged it in and tried to configure it.
It had a password set on it. Great.
So I tried all the easy ones, password, cisco, etc. No go.
So I called my friend Charles, whom I knew would know. Of course he did.
You have to have serial access (which I do, of course) and then you hit Ctrl-C while it’s booting up. Then you can erase the config using the command “es 6” followed by “rb” to reboot and all is well.
This is all documented on the Cisco site here: Password Recovery Procedure for the Cisco 6xx CPE.
Thanks Charles!
