DRAFT: BROCADE CONFIDENTIAL
To configure VLAN membership, perform the following steps in global configuration mode.
1. Create the VLAN interfaces on the Brocade FCoE hardware using the CEE CLI. For details, see
“Creating a VLAN interface” .
The following example creates two VLAN interfaces and assigns each one to a server group.
switch(config)#interface vlan 10
switch-cmsh(conf-if-vl-10)#description server group 1
switch(config)#interface vlan 20
switch-cmsh(conf-if-vl-20)#description server group 2
switch(config)#interface vlan 100
switch-cmsh(conf-if-vl-100)#description server group 3
2. (Optional) Apply the VLAN classifier group to any CEE interface. For details, see “Activating a
VLAN classifier group with an interface port” .
3. Enter the copy command to save the running-config file to the startup-config file.
switch(config)#do copy running-config startup-config
CEE map configuration
The CEE Quality of Service (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, the Priority Group Table and the Priority
Table.
The CEE Priority Group Table defines each Priority Group ID (PGID) and its scheduling policy (Strict
Priority versus Deficit Weighted Round-Robin (DWRR), DWRR weight, relative priority), and partially
defines the congestion Priority Flow Control (PFC) configuration. There are 16 rows in the CEE
Priority Group Table.
Table 11 presents the default CEE Priority Group Table configuration.
NOTE
Only a single Class-of-Service (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.
