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 VLAN and
map the VLAN to a VSAN. fcoe enable [ vsan
vsan-id ]
By default, FCoE is disabled for a VLAN.
Make sure the VSAN to be mapped has
been created.
Setting 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 an FC-MAP value is set, VFC interfaces perform a renegotiation. The same FC-MAP value is
required for two VFC interfaces to negotiate successfully.
To set an FC-MAP value:
Step Command Remarks
1. Enter system view. system-view N/A
2. Set an FC-MAP value. fcoe fcmap fc-map The default setting is 0x0EFC00.
Setting 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.
The following workflow is used to maintain the virtual link established with a peer switch:
1. The switch sends unsolicited Discovery Advertisements every FKA advertisement interval out of its
VFC interfaces in E mode.
The FKA advertisement interval value is carried in unsolicited Discovery Advertisements.
2. After receiving an unsolicited Discovery Advertisement, the peer switch maintains the status of the
virtual link and records the FKA advertisement interval value.
3. If the peer switch fails to receive an unsolicited Discovery Advertisement within 2.5 FKA
advertisement intervals, it deletes the virtual link.
The following workflow is used to maintain the virtual link established with a peer ENode:
4. The switch sends unsolicited Discovery Advertisements every FKA advertisement interval out of its
VFC interfaces in F mode.
The FKA advertisement interval value is carried in unsolicited Discovery Advertisements.
5. After receiving an unsolicited Discovery Advertisement, the peer ENode maintains the status of the
virtual link and records the FKA advertisement interval value.
6. 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
