260 | IPv4 Routingw w w . d e l l . c o m | s u p p o r t . d e l l . c o m Implementation InformationIn FTOS, you can configure any IP address as a static route except IP addresses already assigned tointerfaces.Configuration Task List for IP AddressesThe 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 InterfaceReference Guide.Assign IP Addresses to an InterfaceAssign primary and secondary IP addresses to physical or logical interfaces (for example, a virtual localarea network [VLAN] or port channel) to enable IP communication between the MXL Switch and hostsconnected to that interface. In FTOS, you can assign one primary address and up to 255 secondary IPaddresses to each interface.To assign an IP address to an interface, follow these steps, starting in CONFIGURATION mode:Note: FTOS versions 7.7.1.0 and later support 31-bit subnet masks (/31, or 255.255.255.254) as defined byRFC 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.Step Command Syntax Command Mode Purpose1 interface interface CONFIGURATION Enter the keyword interface followed by the type of interfaceand slot/port information:• For a Loopback interface, enter the keyword loopbackfollowed by a number from 0 to 16383.• For the Management interface, enter the keywordManagementEthernet followed by the slot/portinformation. The slot range is 0/0 and the port range is 0/0.• For a port channel interface, enter the keywordport-channel followed by a number from 1 to 128.• For a 10-Gigabit Ethernet interface, enter the keywordTenGigabitEthernet followed by the slot/portinformation.• For a VLAN interface, enter the keyword vlan followedby a number from 1 to 4094.• For a 40-Gigabit Ethernet interface, enter the keywordfortyGigE followed by the slot/port information.2 no shutdown INTERFACE Enable the interface.
