We are experiencing a lot of "output discards" on our Core Cisco 6509 switch as well as our cisco 3750 switches at several remote sites. Century Link changed our cpe from the Cisco 3400 metroe switch to a device called a "RAD" last August, it has been since then that we have noticed the drops. We have implemented QOS, and also increased the "hold-queue out" parameters to no avail. We can clear the errors and they seem to reappear shortly there after. I was wondering if anyone else is having the same problem or has a solution. One thing I think that has contributed was about the same time we changed two of our main applications to web based apps. We may have a problem with the servers not being able to handle the traffic, hence the discards. We are not seeing any excessive bandwidth being used. Any help or suggestions would be appreciated.
