Dell(conf-if)#
If an interface is in the incorrect layer mode for a given command, an error message displays (shown in bold). In the following
example, the ip address command triggered an error message because the interface is in Layer 2 mode and the ip
address command is a Layer 3 command only.
Dell(conf-if)#show config
!
interface GigabitEthernet 1/2
no ip address
switchport
no shutdown
Dell(conf-if)#ip address 10.10.1.1 /24
% Error: Port is in Layer 2 mode Gi 1/2.
Dell(conf-if)#
To determine the configuration of an interface, use the show config command in INTERFACE mode or the various show
interface commands in EXEC mode.
Configuring Layer 3 (Interface) Mode
To assign an IP address, use the following commands.
Enable the interface.
INTERFACE mode
no shutdown
Configure a primary IP address and mask on the interface.
INTERFACE mode
ip address ip-address mask [secondary]
The ip-address must be in dotted-decimal format (A.B.C.D) and the mask must be in slash format (/xx).
Add the keyword secondary if the IP address is the interfaces backup IP address.
You can only configure one primary IP address per interface. You can configure up to 255 secondary IP addresses on a single
interface.
To view all interfaces to see with an IP address assigned, use the show ip interfaces brief command in EXEC mode as
shown in View Basic Interface Information.
To view IP information on an interface in Layer 3 mode, use the show ip interface command in EXEC Privilege mode.

Automatic recovery of an Err-disabled interface
The Dell EMC Networking OS attempts to recover the interface from the Err-disabled state automatically based on the cause of
the error.
You can configure the Dell EMC Networking OS to recover an interface from Err-disabled state automatically, if the interface is
changed to Err-disabled state due to the following:
