Configuration procedure
To enable FCoE for the specified VLAN and map the VLAN to the specified VSAN:
Step 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 the VLAN to the
specified VSAN.
fcoe enable [ vsan
vsan-id ]
By default, FCoE is disabled for a VLAN.
Make sure 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.
After 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:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure an FC-MAP
value.
fcoe fcmap fc-map The default setting is 0x0EFC00.
Configuring the FKA advertisement interval value
The FKA advertisement interval determines the length of time the switch takes to detect the disconnection
of a virtual link:
• After setting up a virtual link with a peer switch, a switch sends unsolicited Discovery
Advertisements every FKA advertisement interval out of its VFC interfaces in E mode to maintain the
established virtual link. The FKA advertisement interval value is carried in unsolicited Discovery
Advertisements. After receiving an unsolicited Discovery Advertisement, the peer switch maintains
the status of the virtual link and records the FKA advertisement interval value. If the peer switch fails
to receive an unsolicited Discovery Advertisement within 2.5 FKA advertisement intervals, it deletes
the virtual link.
• After setting up a virtual link with a peer ENode, the switch sends unsolicited Discovery
Advertisements every FKA advertisement interval out of its VFC interfaces in F mode to maintain the
established virtual link. The FKA advertisement interval value is carried in unsolicited Discovery
Advertisements. After receiving an unsolicited Discovery Advertisement, the peer ENode maintains
the status of the virtual link and records the FKA advertisement interval value. If the peer ENode fails
to receive an unsolicited Discovery Advertisement within 2.5 FKA advertisement intervals, it deletes
the virtual link. In addition, the ENode sends keepalive frames to the switch every FKA
advertisement interval value (this value is obtained from unsolicited Discovery Advertisements
received from the switch). After receiving a keepalive frame, the switch maintains the status of the
