priority-table
Provisions the CEE Priority-to-Priority Group Table; this table maps each of the eight ingress CoSs
into a Priority Group.
Synopsis priority-table pgid0 pgid1 pgid2 pgid3 pgid4 pgid5 pgid6 pgid7

Operands pgid0 Sets the Priority Group ID for all packets with CoS 0.
pgid1 Sets the Priority Group ID for all packets with CoS 1.
pgid2 Sets the Priority Group ID for all packets with CoS 2.
pgid3 Sets the Priority Group ID for all packets with CoS 3.
pgid4 Sets the Priority Group ID for all packets with CoS 4.
pgid5 Sets the Priority Group ID for all packets with CoS 5.
pgid6 Sets the Priority Group ID for all packets with CoS 6.
pgid7 Sets the Priority Group ID for all packets with CoS 7.
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 CoSs 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.
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.
