Transmit Errors

I have just completed a new installation of NPM 12.01 and I am noticing a significant number of transmit errors on a large number of switch interfaces. When I look at the interface on the switch it shows up as having no discards !

I don't understand why the port on the switch shows no discards but Solarwinds shows a large number !

Below is an extract from Solarwinds Top 15 Errors & Discards and a show interface on the switchport referred to by Solarwinds.

I have had to explain this to my Network engineers,

Transmit Discards; But Router Stats Show No Errors

If you look at the Solarwinds screenshot you provided, there are four (4) columns: Receive Errors, Receive Discards, Transmit Errors, Transmit Discards. In this screenshot you are inquiring about Transmit Discards.

In the Switch screenshot, you are looking at Transmit and Receive Errors.

Like the Solarwinds screenshot indicates, there is a difference between Errors and Discards. Errors are due to device error, cabling, etc. Discards are due to congestion of some kind i.e. QoS drop. In the Switch screenshot look at the entry that says "Total Output Drops" that is value that is displaying for Transmit Discards.
