hello i am playing with qos on some devices - cisco 3560 - cisco 7609 and i have some things that i don't seem to understand. 1. in 3560, i enable mls qos, on the ingress port applyed policy map, classify the packets with acl, mark, all good. on the egress ports i use srr-queue with shape/share, everything is fine, it is working. http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/1... 2. reset to defaults the 3560 in 7606 i pick up a vlan, and apply a policy-map and set dscp 40 on egress of that vlan 3560 in uplinked in 7609 in 3560 i can see the "marked" packets, and i have matches on the dscp set earlier (sh mls qos int xx stat). the problem is: when i apply the srr-queue in 3560 on egress (towards the test port), it does not work. if i enable mls qos on 3560, i cannot match anymore the dscp 40 from the 7609 is it normal? do i have to apply the qos stuff (point1) on all switches i want qos on? i mean, i cannot set dscp in one "core" device and use that in the whole network ? thanks
