To enable and configure the fairness weight, perform the following procedure, beginning in global
configuration mode:
Configuring RPR-IEEE Service Classes Using the Modular QoS CLI
Traffic is directed to the three service classes supported by RPR-IEEE by using the standard Cisco
Modular QoS CLI (MQC). MQC is a CLI structure that allows you to create traffic policies and attach
these policies to interfaces. A traffic policy contains a traffic class and one or more QoS features. A
traffic class classifies traffic, while the QoS features in the traffic policy determine how to treat the
classified traffic.
For more information on general MQC configuration, refer to the following Cisco IOS documents:
• Cisco IOS Quality of Service Solutions Configuration Guide, Release 12.2
• Cisco IOS Quality of Service Solutions Command Reference, Release 12.2
Caution The cos priority-mcast command is not supported under RPR-IEEE on the ML-Series card or accepted.
The command incorrectly shows as an option under the Cisco IOS CLI.
Caution In IEEE-RPR mode if additional class maps are added to a policy map and associated the policy map with a
output interface even if no bandwidth is reserved explicitly, by default 7% bw is allocated and once the
bandwidth reaches more thant 100% further class-map configuration on that policy-map is rejected.
Command Purpose
Step 1
Router(config)# interface rpr-ieee 0
Activates interface configuration mode to
configure the RPR-IEEE interface.
Step 2
Router(config-if)# rpr-ieee fairness weight
weight [east | west]
Specifies the weight for a station on the ringlet.
Values can range from 0 to 7 and are configured as
an exponent of 2, which results in weights ranging
from 1 to 128. The default value is zero.
(Optional
Step 3
Router(config)# no shut
Enables the RPR-IEEE interface and changes the
mode from the default passthrough.
Step 4
Router(config)# end
Returns to privileged EXEC mode.
Step 5
Router# copy running-config startup-config
(Optional) Saves configuration changes to the
TCC2/TCC2P flash database.
