We usually use this QoS config to give voice traffic priority: class-map match-all VOICE match ip dscp ef policy-map BRANCH-WAN-EDGE_child class VOICE priority percent 10 class class-default fair-queue random-detect dscp-based policy-map BRANCH-WAN-EDGE_parent class class-default shape average 100000000 service-policy BRANCH-WAN-EDGE_child interface GigabitEthernet0/1.402 service-policy output BRANCH-WAN-EDGE_parent
But now we have to do this in a 7609 with WS-X6724-SFP cards. The setup is that the WAN lines come in on a 3750 switch, and the 3750 switch is connected to the 7609 on two gigabit ports in different WS-X6724-SFP cards, combined by a port-channel. In the 7609 the WAN VLAN is terminated like this: interface Vlan402 bandwidth 100000 ip address xxx All physical ports in the 7609 trust dscp: mls qos trust dscp Other than that we only have this QoS config in the 7609: mls qos mls qos map cos-dscp 0 8 16 24 32 46 48 56 I tried our usual config and some other variants, but the 7609 won't accept shaping or priority or hierarchical QoS. Probably because it doesn't have real WAN cards since the WAN lines are connected to the 3750. Is there any way to do what we want in the 7609? The only requirement right now is to give priority to traffic marked with dscp ef. We would prefer to configure this priority per VLAN if possible, but will do it on the physical interfaces (or maybe on the port-channel?) if that's the only way. A possible complication is that the WAN lines have different bandwidth. Usually 50 Mbps, but some are 100 Mbps. This is why priority configuration per VLAN is preferred.
