I have a handfull of Cat 3560 switches in wireclosets and I would like to implement some basic QoS for limited VoIP (it's an add-on to an older PBX we have, not a full blown implementation) and some video conferencing equipment. Basically, I want to mark VoIP traffic to DSCP 46, video to DSCP
34, normal data traffic to DSCP 0 and "scavenger" traffic to DSCP 8. That part is pretty straight foward. It's the queuing I'm not 100% on. Take a look, all suggestions are welcome.version 12.1 ! mls qos map policed-dscp 0 34 46 to 8 mls qos map cos-dscp 0 18 16 24 32 46 48 56 mls qos srr-queue output cos-map queue 2 threshold 1 4 mls qos srr-queue output cos-map queue 3 threshold 1 0 6 7 mls qos srr-queue output cos-map queue 4 threshold 1 1 mls qos srr-queue output dscp-map queue 2 threshold 1 34 mls qos srr-queue output dscp-map queue 3 threshold 1 0 mls qos srr-queue output dscp-map queue 4 threshold 1 8 mls qos ! class-map match-all VIDEO match access-group name VIDEO class-map match-all VOICE match access-group name VOICE ! ! policy-map VOICE-VIDEO-PC-SCAV class VOICE set ip dscp 46 police 128000 8000 exceed-action drop class VIDEO set ip dscp 34 police 5000000 8000 exceed-action policed-dscp-transmit class class-default set ip dscp 0 police 5000000 8000 exceed-action policed-dscp-transmit ! ! spanning-tree mode pvst no spanning-tree optimize bpdu transmission spanning-tree extend system-id ! ! interface FastEthernet0/1 no ip address srr-queue bandwidth share 1 60 40 5 srr-queue bandwidth shape 3 0 0 0 priority-queue out mdix auto spanning-tree portfast ! .... ! interface FastEthernet0/24 no ip address srr-queue bandwidth share 1 60 40 5 srr-queue bandwidth shape 3 0 0 0 priority-queue out mdix auto spanning-tree portfast ! interface GigabitEthernet0/1 switchport trunk encapsulation dot1q switchport mode trunk no ip address srr-queue bandwidth share 1 60 40 5 srr-queue bandwidth shape 3 0 0 0 priority-queue out mls qos trust dscp ! interface GigabitEthernet0/2 switchport trunk encapsulation dot1q switchport mode trunk no ip address srr-queue bandwidth share 1 60 40 5 srr-queue bandwidth shape 3 0 0 0 priority-queue out mls qos trust dscp ! ip access-list extended VIDEO permit ip access-list extended VOICE permit !
