7. Define Priority Group mapping for groups 0 – 7.
BR8K-21-cmsh(conf-ceemap)# priority-table 2 2 2 1 2 2 2 2
NOTE: COS: 0 1 2 3 4 5 6 7
NOTE: COS 3 is the default for FCoE. Don’t try to change it, because the rest of the world is expecting it to
be COS 3.
8. Configure LLDP/DCBX for FCoE.
BR8K-21-cmsh(config)#protocol lldp
BR8K-21-cmsh(conf-lldp)# advertise dcbx-fcoe-app-tlv
1
BR8K-21-cmsh(conf-lldp)# advertise dcbx-fcoe-logical-link-tlv
2
NOTE:
1
Advertises the DCBX FCoE application TLV
2
Advertises the DCBX FCoE logical link TLV
DCBX: Data Center Bridging Exchange protocol. Creates a lossless communication environment.
TLV: Type Length Value. Mandatory LLDP data structures within the Ethernet frame, including chassis ID,
Port ID, time to live, and so on.
9. Configure CEE port for FCoE.
BR8K-21-cmsh(config)#int te 0/0
BR8K-21-cmsh(conf-if-te-0/0)#switchport Enable L2 switching mode
BR8K-21-cmsh(conf-if-te-0/0)#switchport mode converged
3
BR8K-21-cmsh(conf-if-te-0/0)#switchport converged allowed vlan add 3
Enable VLAN 3 on this I/F
BR8K-21-cmsh(conf-if-te-0/0)# vlan classifier activate group 1 vlan 3
4
BR8K-21-cmsh(conf-if-te-0/0)# cee demo Assign CEE map to port
BR8K-21-cmsh(conf-if-te-0/0)# no shut Enable the port
NOTE:
3
I/F could be untagged (access) in one VLAN and tagged (trunk) in another VLAN. Trunk allows multiple
VLAN associations and tagged frames. Converged allows both.
4
Activate group 1 rule on this port for VLAN 3 (defined earlier)
10. Verify CNA is logged into the switch.
BR8K-21-cmsh(conf-if-te-0/0)#do fos switchshow Look for logged-in VN-Ports.
BR8K-21-cmsh(conf-if-te-0/0)#do fos nsshow Look for expected FC/FCoE devices
BR8K-21-cmsh(conf-if-te-0/0)#exit Exit port config
BR8K-21-cmsh(config)#exit Exit config mode
11. Save your configuration.
BR8K-21-cmsh#copy run start
BR8K-21-cmsh#exit Exit cmsh mode
BR8K-21:admin> Return to FOS
Saving the configuration copies the running configuration to the startup configuration, which is preserved
across reboots. The running configuration is a temporary copy and is lost during a reboot.
