CEE map configuration 5

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-configfile to the startup-configfile.

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.
