Hi members,
I am currently troubleshooting a Gig interface that has increasing total output drops value.
The Gig interface is connecting to a switch. We use subinterfaces on the router to connect to different circuits.
I noticed that the total output drops value we have on the GiG interface matches the packets being dropped on one of the subinterfaces due to qos policy. The subinterface only is limited to 30M and will be dropped if there is violation of this CIR.
My question is , is there a specific command , "show interface" whatever that will tell that the total output drops is due to QoS policies instead of the Gig interfaces being congested ??
Thank you.

Hello,
the command:
show policy-map interface X
should tell you what your policy does and if packets are being dropped due to the policy being configured on your interface...

Hello Mark,
as far as I know the show policy-map interface is the only command that allows you to perform this kind of checks.
This show command accepts additional parameters so that you can see only input section or output section and you can also specify a class-map <name>.
This can be handy if you know what class(es) are experiencing drops.
Of course, some calculations are needed.
Hope to help
