Configuring the Switch for iSCSI over DCBX
Configuring the Brocade 8000 CEE switch involves the following steps:
1. Verify the Version of the Switch Firmware
2. Create and Configure the iSCSI VLAN on the Switch
3. Create and Configure the CEE Map for iSCSI Traffic Bandwidth and PFC
4. Configure LLDP/DCBX for the iSCSI TLV
5. Configure the CEE Port’s iSCSI Traffic Class
6. Verifying Adapter/Switch Status for iSCSI Login, Traffic, and PFC
Verify the Version of the Switch Firmware
The switch firmware must be version 6.4.1 or later to support the iSCSI TLV. To
check the switch firmware version, issue the following command:
admin> version
Update the switch firmware if the version is earlier than 6.4.1. For instructions on
updating the firmware, refer to the switch's documentation.
Create and Configure the iSCSI VLAN on the Switch
Issue the following commands to create the iSCSI VLAN on the switch.
admin> cmsh
# configure terminal
swd77(config)#interface vlan 99
swd77(conf-if-vl-99)#exit
The preceding commands create a VLAN with VLAN ID 99 on the switch.
Create and Configure the CEE Map for iSCSI Traffic Bandwidth and PFC
In this example, the following commands are issued to set iSCSI traffic for
90 percent bandwidth and PFC with group ID 7 and to set all other traffic for
10 percent bandwidth and no PFC with group ID 6.
1. Create a CEE map with name iscsi-dcbx:
>swd77(config)#cee-map iscsi-dcbx
2. Allocate 90 percent bandwidth for the priority traffic in group 7:
swd77(conf-ceemap)#priority-group-table 7 weight 90 pfc
3. Allocate 10 percent bandwidth for the nonpriority traffic in group 6:
swd77(conf-ceemap)#priority-group-table 6 weight 10
4. Map COS to group for the allocated traffic:
