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 following 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.
