Chapter 18: Ethernet Services and Interfaces (CLI)
Configuring a Service's CoS Mode and Default CoS (CLI)
The CoS mode determines whether or not frames passing through the service have their CoS modified at the
service level. The CoS determines the priority queue to which frames are assigned.
The CoS of frames traveling through a service can be modified on the interface level, the service point level, and
the service level. The service level is the highest priority, and overrides CoS decisions made at the interface and
service point levels. Thus, by configuring the service to apply a CoS value to frames in the service, you can define a
single CoS for all frames traveling through the service.
To set a service's CoS mode, go to service view for the service and enter the following command:
service[SID]>service cos-mode set cos-mode <cos-mode>
If the CoS mode is set to default-cos
the Default CoS:
service[SID]>service default-cos set cos <cos>
