Fcoe Enable; Fcoe Fcf-Priority - HP 6127XLG Blade Series Command Reference Manual

fcoe enable

Use fcoe enable to enable FCoE in a VLAN and map the VLAN to a VSAN.
Use undo fcoe enable to disable FCoE in a VLAN.
Syntax
fcoe enable [ vsan vsan-id ]
undo fcoe enable
Default
FCoE is disabled in a VLAN.
Views
VLAN view
Predefined user roles
network-admin
Parameters
vsan vsan-id: Specifies a VSAN by its ID in the range of 1 to 3839. If you do not specify a VSAN, this
command maps the VLAN to a VSAN with the same number as the VLAN. For VLANs 3840 to 4094,
you must manually specify VSANs to be mapped.
Usage guidelines
FCoE cannot be enabled in VLAN 1.
Do not enable FCoE in a reserved VLAN. If you enable FCoE in a reserved VLAN, the VFC interfaces
assigned to the mapped VSAN as trunk ports cannot come up. For more information about reserved
VLANs, see Layer 2—LAN Switching Command Reference.
VSANs are mapped to VLANs on a one-to-one basis.
An FCoE-enabled VLAN allows only FCoE traffic. All member ports in an FCoE-enabled VLAN are
isolated and will not form loops. To prevent FCoE links from being blocked, do not enable STP or other
loop detection protocols in an FCoE-enabled VLAN. A Layer 2 protocol enabled in an FCoE-enabled
VLAN runs based on the topology where all member ports in the VLAN are isolated at Layer 2.
When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface
might allow multiple VLANs. You must enable FCoE in the same VLAN and map the VLAN to the same
VSAN on both ends. Then, the packets from the VSAN are tagged with the VLAN tag and transmitted
within the VLAN.
Examples
# Enable FCoE in VLAN 4 and map VLAN 4 to VSAN 6.
<Sysname> system-view
[Sysname] vlan 4
[Sysname-vlan4] fcoe enable vsan 6

fcoe fcf-priority

Use fcoe fcf-priority to set the FCF priority for a VFC interface.
Use undo fcoe fcf-priority to restore the default.
