Cisco Router Debugging on VTY line


Cisco Router Debugging

Virtual Terminal Logging

Enable Debugging on Virtual Terminal

In order to enable debugging messages on your virtutal terminal, type:
undebug all
conf t
logging monitor debugging
logging on
exit

Debug

Cisco routers can debug a whole lot of things. Let's try a simple example:
debug ip ospf hello

How do I turn this off again?

Yeah, right. You're sick of all those messages and want to get rid of them without logging out and all this. Here you go:
undebug all
terminal no monitor
conf t
no logging monitor
exit
