Description

This command configures the update mode of the list of FCFs per FIP Snooped VLAN (Virtual LAN). The default mode is auto.

The list of FCFs to which ENodes establish FCoE virtual links is updated either administratively or dynamically via snooped FIP frames. This command selects the method of updating the list of FCFs per VLAN. When the updating method changes, the following events occur.

In automatic mode, the list of FCFs is automatically constructed through observation of FCF discovery advertisement packets. An attempt to configure an FCF while in automatic mode is rejected.
