DRAFT: BROCADE CONFIDENTIAL 9 Converged Enhanced Ethernet map configuration Converged Enhanced Ethernet map configuration The CEE QoS covers frame classification, priority and traffic class (queue) mapping, congestion control, and scheduling. Under the CEE Provisioning model all of these features are configured utilizing two configuration tables, Priority Group Table and Priority Table. CEE Priority Group Table defines each Priority Group ID (PGID) and its scheduling policy (Strict Priority versus DWRR, DWRR weight, relative priority), and partially defines the congestion control (PFC) configuration. There are 16 rows in the CEE Priority Group Table. Table 21 presents the default CEE Priority Group Table configuration. NOTE 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. TABLE 21 PGID 15.0 15.1 15.2 15.3 15.4 15.5 15.6 15.7 0 1 2 3 4 5 6 7 Default CEE Priority Group Table configuration Bandwidth% PFC - N - N - N - N - N - N - N - N 0 N 0 N 0 N 0 N 0 N 0 N 0 N 0 N Strict Priority versus DWRR is derived directly from the PGID value. All PGIDs with prefix 15 receive Strict Priority scheduling policy and all PGIDs in the range 0 through 7 receive DWRR scheduling policy. Relative priority between Priority Group is exactly the ordering of entries listed in the table, with PGID 15.0 being highest priority and PGID 7 being 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 Priority Group is not known, which leads into the CEE Priority Table. 106 Converged Enhanced Ethernet Administrator's Guide 53-1001761-01

Converged Enhanced Ethernet map configuration

DRAFT: BROCADE CONFIDENTIAL

Converged Enhanced Ethernet map configuration

The CEE QoS covers frame classification, priority and traffic class (queue) mapping, congestion

control, and scheduling. Under the CEE Provisioning model all of these features are configured

utilizing two configuration tables, Priority Group Table and Priority Table.

CEE Priority Group Table defines each Priority Group ID (PGID) and its scheduling policy (Strict

Priority versus DWRR, DWRR weight, relative priority), and partially defines the congestion control

(PFC) configuration. There are 16 rows in the CEE Priority Group Table.

Table 21

presents the

default CEE Priority Group Table configuration.

NOTE

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.

Strict Priority versus DWRR is derived directly from the PGID value. All PGIDs with prefix 15 receive

Strict Priority scheduling policy and all PGIDs in the range 0 through 7 receive DWRR scheduling

policy. Relative priority between Priority Group is exactly the ordering of entries listed in the table,

with PGID 15.0 being highest priority and PGID 7 being 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 Priority Group is not

known, which leads into the CEE Priority Table.
