Administrator Guide
At its most basic level, an IP address is 32-bits composed of network and host portions and represented in
dotted decimal format. For example, 00001010110101100101011110000011 is represented as 10.214.87.131.
For more information about IP addressing, refer to RFC 791, Internet Protocol.
Implementation Information
In the Dell Networking OS, you can configure any IP address as a static route except IP addresses already
assigned to interfaces.
NOTE: The Dell Networking OS 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. The system supports RFC 3021 with ARP.
NOTE: Even though Dell Networking OS listens to all ports, you can only use the ports starting from
35001 for IPv4 traffic. Ports starting from 0 to 35000 are reserved for internal use and you cannot use
them for IPv4 traffic.
Configuration Tasks for IP Addresses
The following describes the tasks associated with IP address configuration.
Configuration tasks for IP addresses includes:
• Assigning IP Addresses to an Interface (mandatory)
• Configuring Static Routes (optional)
• Configure Static Routes for the Management Interface (optional)
For a complete listing of all commands related to IP addressing, refer to the Dell Networking OS Command
Line Interface Reference Guide.
Assigning IP Addresses to an Interface
Assign primary and secondary IP addresses to physical or logical (for example, [virtual local area network
[VLAN] or port channel) interfaces to enable IP communication between the system and hosts connected to
that interface.
In the system, you can assign one primary address and up to 255 secondary IP addresses to each interface.
1 Enter the keyword interface then the type of interface and slot/port information.
CONFIGURATION mode
interface interface
• For a Loopback interface, enter the keyword loopback then a number from 0 to 16383.
• For the Management interface on the RPM, enter the keyword ManagementEthernet then the
slot/port information. The slot range is from 0 to 1. The port range is 0/0.
• For a port channel interface, enter the keywords port-channel then a number from 1 to 128.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port
information.
