T3 and Ouput Drop

[PinkLips]

I've got a T3 interface and it's taking alot of output drops (output drops: 409083). Users are reporting intermitten connecitivty problems. ISP has verified that the curcuit is clean and the other endpoint interface is clean. What does the output drops mean? What are some possible reason why this is happening.

Normally that occurs when the interface get's more data than it can forward and it's queue fills up.

To verify if this is your problem, do the following:

interface serial1/0
load-interval 30
!puts the timer counters to 30second sampling

Now when you are experiencing the Internet outage/slowness... Do a show interface serial1/0. Look under the txload and the 30 second output rate.
