I have intermapper installed, monitoring a large wide area network.
Several routers are showing TX Discards = xxxx/minute when using the snmp traffic probe. Can someone please tell me what smnp variables make up the TX Discard counter? I am trying to figure out what is happening because many routers have large TX discards.

I am guessing since we are using Qos policies on these routers, I'm seeing QoS drops, but not sure.

It's ifOutDiscards in the ifTable. In theory, I think, the discards should indicate packets discarded because of things like resource limitations. In practice, we have seen some SNMP implementations which count other types of discards, such as discards due to firewall rules, in this number.
