Cisco 3650 High Total Output Drops

[dtran]

Hello everyone !!! Hope everyone is doing well !!

I've got a few Cisco 3650 switch stacks running IOS-XE 03.06.08E and I am seeing high Total Output Drops across pretty much all active interfaces. I have these switches in production for over a year now and I have not heard of any users reporting connectivity or network related issues so far. Has anyone run into this issue ? is this something I should be concerned about ? or could it be a cosmetic issue ?

Below is a screenshot of the "show interface" command outputs on one of the interfaces,

Thanks all in advance !!!

Looks like the aforementioned bug should not impact you if you are on IOS-XE 03.06.08E as stated; fixed in 3.6(7)E, one release prior.  That said, Cisco may not have truly resolved it.  Are these incrementing at a steady rate, regardless of network load?

Have you tried "qos queue-softmax-multiplier 1200" under the global config?

The details of the Bug ID are rarely accurate.  Affected Versions and Fixed Versions are not to be trusted. 

Always raise a TAC Case in order to get an accurate answer.

That command won't work in 3.X.X.  

The switch will take the command but the function won't work -- CSCvd38417.

It looks that the Total Output Drops is incrementing only when txload is high, 

Thanks gents for replying to my post !!!! I will touch base with TAC
