Re: Login failure


do you have "aaa new-model" enabled?

If so:  Disable it if you don't need AAA.

Otherwise some additional configuration will be necessary.

Hope that helps



Oh, you can't login at the moment, right?

Do you have SNMP (RW) configured, if so you could load a config file per TFTP.

If not: What about console access?

Worst case would be password recovery or autoinstal with a revised config file.

Here is a link that can assist with making sure you have everything you are looking for:

There are a couple of things to check, as mentioned already check and see if you have any AAA configuration.  It is possible that AAA is causing some issues.  The second thing is to remove the usermane and password and re-add it back in.  Keep in mind that it is case sensitive.  One other change I would make, it is not really an issue, is the priv 15 I would add to the username config and not on the vty.
