i had problems on a 3750 with the command "show policy-map interface"there was a traffic-shaping configured - but the counters didn't change the value (always zero) - with different s/w versionsideas here?
that's not the way it works on a Catalyst. QoS on Cisco Switches is completely different than QoS on Cisco Routers.

if i want to get one-way jitter, can i do simply rtt/2 ?
no, perhaps the jitter is only in one direction? http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_44_se/configuration/guide/swipsla.html
