For more information on IP addressing, refer to RFC 791,
Internet Protocol.
Implementation Information
In FTOS, you can configure any IP address as a static route except IP addresses already assigned to
interfaces.
Configuration Task List for IP Addresses
The following list includes the configuration tasks for IP addresses:
• Assign IP addresses to an interface (mandatory)
• Configure static routes (optional)
• Configure static routes for the management interface (optional)
For a complete listing of all commands related to IP addressing, refer to
FTOS Command Line Interface

.
Assign IP addresses to an interface
Assign primary and secondary IP addresses to physical or logical (for example, VLAN or port channel)
interfaces to enable IP communication between the E-Series and hosts connected to that interface. In
FTOS, you can assign one primary address and up to 255 secondary IP addresses to each interface.
Note: FTOS versions 7.7.1.0 and later support 31-bit subnet masks (/31, or 255.255.255.254) as defined by
RFC 3021. This feature allows you to save two more IP addresses on point-to-point links than 30-bit masks.
FTOS supports RFC 3021 with ARP.
