Section 5.4.4
Configuring CoS to Priority Mapping
Frames that were received originally untagged and need to be VLAN tagged before being transmitted from a
tagged port, can be automatically assigned a priority value based on the CoS assigned to them internally by
ROS. The mapping between the internal CoS assignment to the external priority value is done based on the
configuration of the CoS access priorities.
To configure rules for CoS-to-priority mapping, do the following:
1. Navigate to Classes of Service » Configure Access Priorities. The Access Priorities table appears.
