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.
● For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
2. Enable the interface.
INTERFACE mode
no shutdown
3. Configure a primary IP address and mask on the interface.
INTERFACE mode
ip address ip-address mask [secondary]
● ip-address mask: the IP address must be in dotted decimal format (A.B.C.D). The mask must be in slash prefix-
length format (/24).
● secondary: add the keyword secondary if the IP address is the interface’s backup IP address.
To view the configuration, use the show config command in INTERFACE mode or use the show ip interface command
in EXEC privilege mode, as shown in the second example.
Example the show config Command
Dell(conf-if-te-0/16)#show conf
!
interface TenGigabitEthernet 0/16
no ip address
shutdown
Dell(conf-if-te-0/16)#
