Variable definitions
The following table describes the variables and values for configuring port-based QoS.
Configuring queue settings
Complete this procedure to define the queue settings for a specific port. Set the minimum and
maximum threshold values for the Two Rate Three Color Marker (TRTCM) police type.
Queues 0, 1, and 2 are configured as strict priority queues. The weights for these queues default to
0 and cannot be changed. The weights of the remaining queues (queues 3 to 7) can be any value
within the range except 0. The remaining queues are configured as weighted round robin (WRR).
Packets received in strict priority queues receive immediate service from the scheduler, thereby
pre-empting scheduling for WRR queues.
Procedure steps
Step Action
1 Enter global configuration mode:
configure terminal
2 Enter:interface configuration mode:
interface <interface-type> <interface-id>
3 Configure the RED parameters of a queue:
queue threshold <queue-number> <min-green-threshold>
<max-green-threshold> <min-amber-threshold>
<max-amber-threshold>
4 Configure the weight of the queue:
queue weight <queue-number> <queue-weight>
Variable Value
interface-type
Type of the ingress L3 interface. The physical or virtual interface type.
interface-id
The specific interface of the interface type.
priority-value
The priority for the traffic class. Values range from 0 to 7.
traffic-class
The traffic classes supported on the port.
The values ranges from 0 to7.
Note: If you add a DSL or T1/E1 WAN configuration, the PPP interface you
created appears in the Port No drop-down list. You can select and configure the
PPP interface. The defaults for the PPP interface are the same as the defaults for
the other ports. If you delete the DSL or T1/E1 WAN configuration, it no longer
appears as a selection in the Port No drop-down list.
