Defaults
The default CEE Priority mapping table matches the IEEE 802.1Q recommendation for systems
supporting eight traffic classes. The 802.1Q maps CoS 0 (best effort) to Strict Priority Traffic Class
1 (PGID 15.6) and CoS 1 to below best effort Traffic Class 0 (PGID 15.7). All other CoS values go
through unchanged, for example CoS 2 maps to Traffic Class 2 (PGID 15.5), up to CoS 7 and Traffic
Class 7 (PGID 15.0).

Command
Modes
CEE Map Configuration mode
Description
Use this command to provision the CEE Priority-to-Priority Group Table. This table maps each of the
eight ingress CoS into a Priority Group. Use the no priority-table command to return the Priority
mapping table to the default values.
eight ingress CoS into a Priority Group. Use the no priority-table command to return the Priority
mapping table to the default values.
Usage
Guidelines
Only a single CoS can be mapped to a PFC-enabled priority queue. The CoS number must be
identical to the priority queue number. If your configuration violates this restriction an error
message displays and the Priority Group Table is set back to the default values.
identical to the priority queue number. If your configuration violates this restriction an error
message displays and the Priority Group Table is set back to the default values.
When the CEE map is applied, and the interface is connected to the CNA, only one strict priority
PGID (PGID 15.0 to PGID 15.7) is allowed.
PGID (PGID 15.0 to PGID 15.7) is allowed.
