RE: What about the troubleshooting part - allowed commands

I think he's referring to an "old wives tale" about when the CCIE lab
first came out - it was rumored that Cisco had a special IOS running
which disabled the equivalent of a show run. It was just rumors, but
funny, nonetheless.

Hi Dennis,

I have never heard of such a restriction.

A good trouble-shooting technique is always a combination of "show run"
commands, and other show and debug commands.

For example: sometimes its so much easier to troubleshoot by comparing
configurations of two routers.

There are even some TS tasks which you just can't use show commands to
solve, as they can't be tested in the lab, such as some IP services,
some
QoS tasks... etc.

At the end, you will always need the "show run" command to verify that
the
fix you want to apply to the running configuration actually makes sense.

Note: never use just "show run". You always need to be more specific,
like
"show run | section eigrp". To be more specific, you will need the other
show commands.

Last, but not least, make sure you practice TS labs only after you have
finished all other practice labs. You will really need all your skills
to do
TS.
