I'd like some advice on an output drop issue I'm having with a point-to-point T1. The output drops increment up by 200 - 700 every 15 minute interval during business hours. After hours no drops are recorded. Traffic is at approx 50% up and 20% down so the drops shouldn't be from over utilization. (see attached) The traffic on the T1 is 90% HTTP data.
I've read other posts recommending a larger hold-queue. Before I made any changes, I wanted to see what the community thought and if there were any other recommendations.
Is there a hold-queue that is an âindustry standardâ?
Should the A end and Z end serial interfaces have symmetrical hold-queue settings?
Any help would be greatly appreciated.
