If you pre-configured this interface for FMC access management, then the interface will already be
named, enabled, and addressed. You should not alter any of these basic settings because doing so
will disrupt the FMC management connection. You can still configure the Security Zone on this
screen for through traffic policies.
• IPv4—Choose Use DHCP, and configure the following optional parameters:
• Obtain default route using DHCP—Obtains the default route from the DHCP server.
• DHCP route metric—Assigns an administrative distance to the learned route, between 1 and
