I used to see these exact same results when I would setup Wireless pop's on towers taller than 400Ft. I was able to push the envelope a bit, however when I saw the issues that you speak of, it was when I had bad crimps, or sometimes a bad cable all together. Cat5 should be fine for this... if you figure 12ft risers you are probably cutting it close on the distance but not going over it. -Scotty ----- Original Message ----- From: "Steve Rude" <steve@rudedogg.com> To: <nanog@merit.edu> Sent: Friday, January 10, 2003 3:01 PM Subject: fast ethernet limits
Hi NANOG,
Could someone please help me with a fast ethernet problem I am having. We have a POP in a 27 floor building, and have a rj45 run from the the bottom of the building (in the telco room) to the top of the building. We have cisco switches on either end and we are seeing about 5-20% packet loss on the trunk.
Are we running into a distance limitation of fast ethernet, or are we
suffering
from another problem? I read that 328 feet is the limitation of fast ethernet. Is there anything short of getting a repeater for the cable run that I can do to boost the signal?
TIA for your help.
Ciao.
