Strict Priority versus DWRR is derived directly from the PGID value. All PGIDs with prefix 15 receive the Strict Priority scheduling policy and all PGIDs in the range 0 through 7 receive the DWRR scheduling policy. Relative priority between PGIDs is exactly the ordering of entries listed in the table, with PGID 15.0 being the highest priority and PGID 0 being the lowest priority. Congestion control configuration is partially specified by toggling the PFC column On or Off. This provides only partial configuration of congestion control because the set of priorities mapped to the PGID is not known.

The CEE Priority Table defines each CoS mapping to a PGID, and completes the PFC configuration. There are eight rows in the CEE Priority Table. Table 12 details the default CEE Priority Table configuration.

Defining a Priority Group Table map

To define a priority group table map, perform the following steps from privileged EXEC mode. 1. Enter global configuration mode.

switch#configure terminal

2. Activate the CEE map mode.

switch(config)#cee-map default

3. Define the CEE map for PGID 0.

switch(config-ceemap)#priority-group-table 0 weight 50 pfc
