Fcoe Fcf-Priority - HP 5920 Series Command Reference Manual

All member ports in an FCoE-capable VLAN are isolated and will not form loops. For this reason,
•
you do not need to enable STP or other loop detection protocols in an FCoE-capable VLAN.
Otherwise, FCoE links might be blocked.
• A Layer 2 protocol enabled in an FCoE-capable VLAN runs based on the topology where all
member ports in the FCoE-capable VLAN are isolated at Layer 2.
Examples
# Enable FCoE on VLAN 4 and map VLAN 4 to VSAN 6.
<Sysname> system-view
[Sysname] vlan 4
[Sysname-vlan4] fcoe enable vsan 6

Usage guidelines
The VFC interface FCF priority is used in the fcf priority field in an unsolicited Discovery Advertisement.
An ENode selects the FCF switch with the highest priority from the FCF switches sending Discovery
Advertisements and sends a FLOGI request to it for login.
This command is takes effect on only VFC interfaces operating in F mode. You can configure this
command on VFC interfaces operating in E mode, but it does not take effect.
