To view which interfaces are enabled for Layer 3 data transmission, use the show ip interfaces
brief command in EXEC Privilege mode. In the following example, TengigabitEthernet interface 1/5 is in
Layer 3 mode because an IP address has been assigned to it and the interface’s status is operationally up.
Dell#show ip interface brief
Interface IP-Address OK? Method Status Protocol
TengigabitEthernet 1/0 unassigned NO Manual administratively down down
TengigabitEthernet 1/1 unassigned NO Manual administratively down down
TengigabitEthernet 1/2 unassigned YES Manual up up
TengigabitEthernet 1/3 unassigned YES Manual up up
TengigabitEthernet 1/4 unassigned YES Manual up up
TengigabitEthernet 1/5 10.10.10.1 YES Manual up up
TengigabitEthernet 1/6 unassigned NO Manual administratively down down
TengigabitEthernet 1/7 unassigned NO Manual administratively down down
TengigabitEthernet 1/8 unassigned NO Manual administratively down down
To view only configured interfaces, use the show interfaces configured command in the EXEC
Privilege mode. In the previous example, TengigabitEthernet interface 1/5 is in Layer 3 mode because an
IP address has been assigned to it and the interface’s status is operationally up.
To determine which physical interfaces are available, use the show running-config command in EXEC
mode. This command displays all physical interfaces available on the line cards.

Enabling a Physical Interface
After determining the type of physical interfaces available, to enable and configure the interfaces, enter
INTERFACE mode by using the interface interface slot/port command.
1. Enter the keyword interface then the type of interface and slot/port information.
CONFIGURATION mode
interface interface
• For the Management interface, enter the keyword ManagementEthernet then the slot/port
information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port
information.
