Hi all,
When it comes to the big day, can anyone think of a good reason not to
'shutdown' all switch ports first, enabling only the ports required by
the specific lab topology?
In other words, literally "int range fa0/1-24" (or as appropriate),
"shutdown" everything, then as you're working through the lab guide,
configuring ports/assigning VLANs/creating Etherchannels etc.,
enabling ports as you go?
Apart from the obvious potential trap of forgetting to "no shut" a
port, or situations where the task(s) make it clear you are not
permitted to shut anything else down, are there any traps?
I was recently bitten by a problem caused by a switch-to-switch link
that was not part of my lab topology -- I had a flapping EIGRP
neighbour and it was all down to some 'extra' switchports coming in to
play.
Curious about the way other people approach this issue.
cheers,
Dale
