R21xx-HP FlexFabric 11900 FCoE Configuration Guide

Enabling FCoE for a VLAN and mapping a VSAN

to the VLAN

When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface can

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.

Configuration restrictions and guidelines

Follow these restrictions and guidelines when you configure this feature:

• 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.

• Make sure the Ethernet interface bound to the VFC interface allows the FCoE-capable VLAN.

After you enable FCoE for a VLAN, the following changes apply to the VLAN:

• An FCoE-capable VLAN allows only FCoE traffic.

• All member ports in an FCoE-capable VLAN are isolated. For this reason, a Layer 2 protocol

enabled in the FCoE-capable VLAN runs based on the port isolation topology.

Configuration procedure

To enable FCoE for the specified VLAN and map this VLAN to the specified VSAN:

Ste

Command

Remarks

1. Enter system view. system-view N/A

2. Enter VLAN view.

vlan vlan-id N/A

3. Enable FCoE for the specified

VLAN and map this VLAN to the

specified VSAN.

fcoe enable [ vsan

vsan-id ]

By default, FCoE for a VLAN is disabled.

Make sure that the VSAN to be mapped

has been created.

Configuring the FC-MAP value

The FC-MAP value identifies an FCoE network. Switches in the same FCoE network must have the same

FC-MAP value.

IMPORTANT:

fter FC-MAP values are configured, VFC interfaces perform a renegotiation. The same FC-MAP value is

required for two VFC interfaces to negotiate successfully.

To configure an FC-MAP value:
