Attach the QoS profile to an Ethernet port.
8.
(config)#interface fastEthernet 9/0
(config-if)#qos-profile qpDiffServExample
(config-if)#exit
Figure 39 on page 139 shows this configuration with 3 users: IP 1, IP 2, and IP 3.
IP 1 subscribes to data, video, and voice services.
IP 2 subscribes to data and video services.
IP 3 subscribes to data and voice services.
The following set of commands configures the QoS profile detailed in Step 7 previously.
Each line in the profile is known as a profile rule. The numbers associated with each rule
correspond to the numbers in Figure 39 on page 139.
(config)#qos-profile qpDiffServExample
(1) (config-qos-profile)#ethernet group best-effort scheduler-profile bestEffortGroup
(2) (config-qos-profile)#ethernet group assured-fwd scheduler-profile assuredGroup
(3) (config-qos-profile)#ethernet group expedited-fwd scheduler-profile expeditedGroup
(4) (config-qos-profile)#ip node group best-effort scheduler-profile default
(5) (config-qos-profile)#ip node group assured-fwd scheduler-profile default
(6) (config-qos-profile)#ip node group expedited-fwd scheduler-profile default
(7) (config-qos-profile)#ip queue traffic-class voice scheduler-profile voice
(8) (config-qos-profile)#ip queue traffic-class video scheduler-profile video
(9) (config-qos-profile)#ip queue traffic class best-effort scheduler-profile best-effort
When you specify a group rule within an attached QoS profile, nodes and queue may be
attached to group nodes. If the qpDiffServExample QoS profile used in the preceding
example did not contain group rules, then the groups would exist with no attachments.
