3. Enter the copy command to save the running-config file to the startup-config file.

Multicast queue scheduling

The multicast traffic classes are numbered from 0 to 3; higher numbered traffic classes are
considered higher priority. A fixed mapping from multicast traffic class to equivalent unicast traffic
class is applied to select the queue scheduling behavior.

Once the multicast traffic class equivalence mapping has been applied, then scheduling and any
scheduler configuration are inherited from the equivalent unicast traffic class. See
page 118 for details on exact mapping equivalencies.
Unicast ingress and egress queueing utilizes a hybrid scheduler that simultaneously supports
SP+WRR service and multiple physical queues with the same service level. Multicast adds
additional multicast expansion queues. Since multicast traffic classes are equivalent to unicast
service levels, they're treated exactly as their equivalent unicast service policies.
Scheduling the QoS multicast queue
To schedule the QoS multicast queue, perform the following steps from privileged EXEC mode.
1. Enter global configuration mode.
2. Specify the schedule to use and the traffic class to bandwidth mapping.
3. Enter the copy command to save the running-config file to the startup-config file.

CEE map configuration

The CEE QoS covers frame classification, priority and traffic class (queue) mapping, congestion
control, and scheduling. Under the CEE Provisioning model all of these features are configured
utilizing two configuration tables, Priority Group Table and Priority Table.
