Hi there.
I need a help to understand a real problem, or impact, caused by Output Drops on ATM subinterface.
The ATM subinterface have a lot output queue drops reported (and is constantly incrementing), but this, apparently, don't caused any problem on the router or data link.
My doubt is...What a real impact that the output queue drops caused on the router and/or data link?
Router
- Cisco 7206VXR Version 12.0(33)S4
- ATM interface OC3
Output show atm pvc command (this interface have a lot PVC):
