Synopsis

enable last-resort {password | succeed}
no enable last-resort {password | succeed}

Configures

The action to take if the TACACS servers do not respond

Default

Disabled

Description

This command tells the router what to do if the TACACS server times out, and you are using TACACS for the enable password. The password keyword tells the router to prompt for the enable password that is in the configuration. The succeed keyword tells the router to go to enable mode without further action. The latter behavior is very insecure.
