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.

To enable and configure the RPR-IEEE service classes with the MQC, perform the fol lowing procedure,

beginning in global configuration mode:

Command Purpose

Step 1 Router(config)# class-map match-any

class-name

Specifies the user-defined name of the traffic class

and the logical OR operator for all matching

statements under this traffic class.

Step 2 Router(config)# match ip precedence

{ip-precedence-value |

ip-precedence-traffic-label}

Specifies an IP precedence value (0 to 7) used as

match criteria or specifies an IP precedence traffic

label.

Each value variable is mapped to a specific label

variable. Entering the command with a ? in place

of the ip-precedence-value |

ip-precedence-traffic-label variable reveals

the labels and their corresponding values.

Step 3 Router(config)# exit Exits class mode.

Step 4 Router(config)# policy-map policy-name Specifies the name of the service policy to

configure. Service policies link the configured

class maps to Layer 2 traffic priorities, or in this

case, the three service classes of RPR-IEEE.

Note An assignment has to be constructed for

each class map.

Step 5 Router(config)# class class-name Specifies the name of a predefined class, which

was defined with the class-map command, to be

included in the service policy.

Note Each of the three RPR-IEEE classes must

be configured as described in this

procedure.

Step 6 Router(config)# set rpr-ieee service-class

{a | b | c}

Specifies the appropriate RPR-IEEE service class

for the class. The three classes correspond to each

of the three RPR-IEEE service classes. Only one

service class can be configured for each MQC

class.
