3750 switchport - faulty state
|

| Ed Leatherman 2007-09-06, 7:12 pm |
| Hey folks,
Anyone seen this output from a 3750:
switch# show power inline
*snip*
Fa2/0/44 auto faulty 0.0 n/a n/a 15.4
Fa2/0/45 auto faulty 0.0 n/a n/a 15.4
Fa2/0/46 auto faulty 0.0 Ieee PD 2 15.4
Fa2/0/47 auto faulty 0.0 n/a n/a 15.4
Fa2/0/48 auto faulty 0.0 n/a n/a 15.4
Switchports had a phone plugged into 2/0/44, user moved the phone to a few
different jacks and couldnt power up on any of them. I suspect that these
are the same ports that are listed as faulty. Can I assume that the ports
were bad from the start, or would an IP phone with a messed up switch or bad
cabling in the wall cause this faulty state?

| I don't remember the cause but when this happened to me before I think a
shut/no shut on the ports fixed it. I think it had something to do with
power surges or lightning strikes. May have also been a bug but I'm
leaning more towards my first guess (power issues).

| I toggled the power setting to never and back to auto, that also seemed to
clear out the faulty state. Waiting to hear back from the on-site tech if it
fixed the phone, he had to go plug it back in.
