The gig port for CUPC client needs to be marked for dscp3 and guaranteed BW of 32k for CUPC signalling Excess traffic should be marked to dscp 8 and then transmitted. My configuration on the Headquater switch is as follows... mls qos mls qos map cos-dscp 0 8 16 24 32 46 48 56 mls qos map policed-dscp 24 26 to 8 ip access-list extended cupc-sig permit udp IPofCUPserver eq 5060 any permit tcp IPofCUPserver eq 5060 any permit tcp IPofCUPserver eq 2748 any class-map match any cupc-sig match access-group name cupc-sig class cupc-sig police 32000 8000 exceed-action policed-dscp-transmit set dscp cs3 interface GigabitEthernet1/0/4 service-policy input cupc After this I have applied on the HQ switch ... 1) mls qos trust dscp on the trunk port to the HQ router 2) mls qos trust dscp to all ports that connect to the servers 3)mls qos trust device cisco-phone and mls qos trust cos to the ports that connect to the phones. Questions : ==================== 1) Is the above config for the CUPC client correct? Please correct me if it is incorrect 2)Is the configuration of qos for the other ports as indicated correct? 3)Do the port configurations pertaining to QOS need to done on the Branch routers as well (that have the ESW module in them) ? 4) Has anyone seen any negative impact of qos settings on the switch that could break other configs if incorrect ?
