Cisco 2650 Output Drops

[pepe123]

I having problem with at 2650 connected to a T1 Frame relay circuit with 18 remotes. The serial interfaces has no CRC errors and the phone company cannot find a problem, But the sho interface shows a constant increase of output drops. What can be causing this problem. Any help will be appreciated.

make sure the phone company does more than just "checking the physical circuit" They are notorious for doing that, no names mentions SPRINT. If they havent found a problem, get them to send it to their frame relay group and get them to test it. Do you have a way of checking for CRC's, FECN's, and BECN's on the Frame interface? It could be dropping output because of congestion. If you have ip addresses bound to the serial interfaces, gwt into your router and run a extended ping report in priveledged exec mode by doing:

>ping

It should ask you a few questions. I suggest maxing the link out at 1500 size packets, and run it with AT LEAST 100 packets.If its got a weakness, you will see it there.

Do this for all DLCI's until you see which sub interface is showing the drop. If you find one dlci is dropping packets, then look at it as a remote problem. If it is slow and dropping on all, look at your head end.
