Why am I seeing high discards and errrors on my Cisco switches

I noticed outside of the forum a conversation that I think would be beneficial to many Orion users. The SolarWinds customer wanted to know why their Cisco switches were reporting high discards and errors. After further investigation, the customer isolated the issue to be occuring in the morning when users were logging into their PCs. It was recommended for the customer to test whether the issue was related to the computer loading the user's profile from the domain controllers. The test was to login with a local administrator account instead of a domain account and see if the problem persists. The customer was able to isolate that the high discards and errors were related to login issues.

Buffer overflows are another common reason switches will report high discards and errors. Have any of you experienced any other scenarios that have caused switches to report high discards or errors?

We are currently investigating this issue right now, we see this happening to in mutiple interfaces with different types of traffic, from high traffic to low traffic. We are currently working on trying to resolve this issue.

 So far we have had nothing concreate that is causing this issue, We have changed NIC's, drivers, cables moved them to different modules on our 6500's and on some of the systems these things worked on other systems it has not.

We have a tac open with Cisco and are looking in the different hard versions of modules with the newer system, to see if there is any known issues with the type of cards, keep in mind that some of these line cards are coming up to 7 years old, and getting close to MTF, so possible RMA on the cards could fix our problems or not

 

Anyways my 2 cents, I will post more when we have more information
