Figure 39: Diffserv Configuration with Multiple Traffic-Class Groups
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 146.
(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.
For example, the following set of commands configures the same QoS profile, but
with the group removed, as shown in Figure 40 on page 147.
(config)# qos-profile qpDiffServExample
(config-qos-profile)# ip node scheduler-profile defau lt
config-qos-profile)# ip queue traffic-class voice scheduler-profile voice
config-qos-profile)# ip queue traffic-class video scheduler-profile video
config-qos-profile)# ip queue traffic class best-effort scheduler-profile best-effort
