I frequently configure QoS on cat switches. On the 3560 (Standard ipbase image)I configure ACL's to define interesting traffic, then apply these to class/policy maps for marking CoS and DSCP.
From a router connected to the Cat 3560 switch, I see the marks as soon as "mls qos" is enabled on the switch. However, the switch itself shows zero statistics with the following commands: "show ip access-list" and "show policy-map". If I disable "mls qos" on the switch, then the connected router sees no more marks, so I know the switch is doing something. This occurs regardless of whether I have "ip routing" enabled or disabled on the 3560. The image is 12.2(25)SED. This happens on all 3560's that I have configured. Is this a bug, an IOS oversight, or do I need the Enterprise image? I cannot find any related issues or docs related to this in CCO. Thank you.
