Re-enable debugging on router reload

It's a bit embarrassing: I've posted a hint on how to execute commands after a router reload and Aamer figured out something I've wanted to have for years: the ability to automatically start debugging after the router reload.For example, to enable debugging of incoming SSH connections, use the following EEM applet:

event manager applet EnableDebugging
event syslog occurs 1 pattern "%SYS-5-RESTART"
action 1.0 cli command "enable"
action 2.0 cli command "debug ip ssh"

  1. For versions of IOS that don't support EEM but do support the config command 'do', you could modify the config off of the router and add a 'do debug...' command to the end then copy the config back directly into the startup-config. It's messy I know, but it does work.
