Hi,
I am facing some issues in implementing QoS on a 4507 switch (IOS 12.1).I want to mark traffic sent by all CCTV's, ACS/INTERCOM and BMS devices to respective servers from 54 floors.For that i created access-lists,class-maps and policy maps.Then i applied the policy maps to the respective vlan interfaces.The issue is that, though i can see the hit count of the access-lists incresing and packets matched increasing, the packets MARKED remain at 0.I want these packets to be marked with dscp 16.But it seems it is not happening. I am copying some of the configs. Please advice
Thanks and Regards,
Sonu
