Views VLAN view Predefined user roles network-admin Parameters vsan vsan-id: Specifies a VSAN to be mapped to the VLAN. The vsan-id argument is in the range of 1 to 3839. If no VSAN is specified, the VSAN with the same number as the VLAN is mapped. For VLANs 3840 to 4094, you must manually specify VSANs to be mapped. Usage guidelines When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface might allow multiple VLANs. You should enable FCoE for a VLAN and map a VSAN to the VLAN, so that the packets from the VSAN are tagged with the VLAN tag and transmitted within the VLAN. FCoE cannot be enabled for VLAN 1. VSANs are mapped to VLANs on a one-to-one basis. You must enable FCoE for the same VLAN and map this VLAN to the same VSAN on the two ends. An FCoE-capable VLAN allows only FCoE traffic. All member ports in an FCoE-capable VLAN are isolated to avoid loops. For this reason, STP and other loop detection protocols do not need to run in an FCoE-capable VLAN. Otherwise, FCoE links might be blocked. Since all member ports in an FCoE-capable VLAN are isolated, a Layer 2 protocol enabled in the FCoE-capable VLAN runs based on the port isolation topology. Examples # Enable FCoE on VLAN 4 and map VSAN 6 to VLAN 4. system-view [Sysname] vlan 4 [Sysname-vlan4] fcoe enable vsan 6 fcoe fcf-priority Use fcoe fcf-priority to configure the FCF priority for the VFC interface.

Parameters
vsan
vsan-id
: Specifies a VSAN to be mapped to the VLAN. The
vsan-id
argument is in the range of 1 to
3839. If no VSAN is specified, the VSAN with the same number as the VLAN is mapped. For VLANs
3840 to 4094, you must manually specify VSANs to be mapped.
Usage guidelines
When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface
might allow multiple VLANs. You should enable FCoE for a VLAN and map a VSAN to the VLAN, so that
the packets from the VSAN are tagged with the VLAN tag and transmitted within the VLAN.
FCoE cannot be enabled for VLAN 1.
VSANs are mapped to VLANs on a one-to-one basis.
You must enable FCoE for the same VLAN and map this VLAN to the same VSAN on the two ends.
An FCoE-capable VLAN allows only FCoE traffic.
All member ports in an FCoE-capable VLAN are isolated to avoid loops. For this reason, STP and other
loop detection protocols do not need to run in an FCoE-capable VLAN. Otherwise, FCoE links might be
blocked.
Since all member ports in an FCoE-capable VLAN are isolated, a Layer 2 protocol enabled in the
FCoE-capable VLAN runs based on the port isolation topology.
Examples
# Enable FCoE on VLAN 4 and map VSAN 6 to VLAN 4.
<Sysname> system-view
[Sysname] vlan 4
[Sysname-vlan4] fcoe enable vsan 6
fcoe fcf-priority
Use
fcoe fcf-priority
to configure the FCF priority for the VFC interface.
Use
undo fcoe fcf-priority
to restore the default.
