Hi

AFAIK theres none like to show u up which interfaces are down using a debug,but if you use up show ip interface brief it can help u out in giving the desired output.

But again debug can give some o/p as on when some links are going down when you have enabled for those interface..

What debug commands are helpful when troubleshooting ? does the live output from the debug show live from the telnet session ?

Hi

There are different scenarios where you can deploy this debug commands to troubleshoot but again this is not the most recommended tool to use in production environment since it may result in unexpected and undesirable outputs.

you can basically give debug and ? which will yield u the options available which can be used .

it depends on what you are troubleshooting based on the same you can use the options available with the debug command..

But as i mentioned earlier pls avoid using debugging commands in a production/live enviroment.And again

if its gonna ur lab then you always have the liberty to hog up ur boxes.

for debugging outputs to be displayed on the telnet window try terminal monitor that will get u the displays online..
