Configuring the FC-MAP value
IMPORTANT:
A
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.
The FC-MAP value identifies an FCoE network. Switches in the same FCoE network must have the same
FC-MAP value.
To configure an FC-MAP value:

Configuring the FKA advertisement period value
The FKA advertisement period determines the length of time it takes the switch 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 period on its VFC interfaces in E mode to maintain the
established virtual link. The FKA advertisement period 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 period value. If the peer switch fails
to receive an unsolicited Discovery Advertisement within 2.5 FKA advertisement periods, it deletes
the virtual link.
• After setting up a virtual link with a peer ENode, the switch sends unsolicited Discovery
Advertisements every FKA advertisement period on its VFC interfaces in F mode to maintain the
established virtual link. The FKA advertisement period 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 period value. If the peer ENode fails
to receive an unsolicited Discovery Advertisement within 2.5 FKA advertisement periods, it deletes
the virtual link. In addition, the ENode sends keepalive frames to the switch every FKA
advertisement period 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
virtual link. If the switch fails to receive a keepalive frame within 2.5 FKA advertisement periods, it
deletes the virtual link.
