[cisco-voip] what is: "cablelength long 0db"

[Fuermann, Jason]

Yea, I definitely don't want to downplay the so called experts wanting to try it in their troubleshooting. Of course, there are plenty of other commands they don't understand that they'll want to try too :)

I'm sure there are a few cases out there.  I just haven't seen it in over a 100+ cases I've been involved with.  It receives a lot of unjust attention.

I'm going with Go0se on this one. We use to have a circuit that wouldn't work without the cablelength long command. Conversely, I seem to remember the opposite problem with having the command on a short cable causing a circuit not to work.

and today's SAT prep question:

(1) How Lelio feels about not being to forward secondary lines is like Nick feels about:

(a) cablelength long 0db
(b) cablelength long 0db
(c) cablelength long 0db
(d) all of the above.


but seriously, I can remove it then?

I would personally be happy if this command was removed from IOS completely.  Myself and a large number of other people who work with these types of things many times daily have never seen this command do anything.  Except waste troubleshooting time, and have people who would like to have a technical opinion on something they don't know anything about bring it up.  It does that quite well.  There, I said it.

And if you see 'unknown protocol drops' on your interface counters you can ignore that too.

And another thing, why am I running "(C3845-SPSERVICESK9-M), Version 15.0(1)M2"

isn't SP mean ServiceProvider? I'm sure I didn't ask for this.

What are people normally running on their branch voice routers ???
