I have the following message in my serial interface:
Serial0/1 is administratively down, line protocol is down
this means, problem with the physical link?
Greetings,
I need to know, how I can look for history in the router to know if a interface serial is bouncing or how I can monitoring the interface for 24 hours.
Thank a lot,
Instead of switching back and forth between global configuration mode and privilege mode to use a commands, you can remain in global configuration mode and type the do command with the original syntax:
For example:
Router(config)#do show running-config
or
Router(config)#do PING 10.10.10.1
