Hi
I have a 3750G switch with a port that I have setup qos on that is set for dscp but doesn't show any dscp stats
interface FastEthernet1/0/2

Other ports on this switch are showing DSCP stats, just not this port.
You might ask if the packets that are passing through the port have DSCP tags, the answer is yes.
This port connects to another switch that has the following settings and results, ie dscp settings on the packets going through it
.

Anyone got any ideas why this port is not using DSCP ?
Thanks in Advance
