Dell Command Line Reference Guide for the S4048–ON System 9.14.2.8

To remove an interface from Layer 2 mode and place it in Layer 3 mode, enter the no switchport command. If a switchport backup interface is configured, first remove the backup configuration. To remove a switchport backup interface, enter the no switchport backup interface command.

backup

(OPTIONAL) Use this option to configure a redundant Layer 2 link without using Spanning Tree. The keyword backup configures a backup port so that if the primary port fails, the backup port changes to the up state. If the primary later comes up, it becomes the backup.

interface interface

(OPTIONAL) Enter any of the following keywords and the interface information:

• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport] information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.

port-channel

(OPTIONAL) Enter the keywords port-channel if the backup port is a static or dynamic port channel.

mode

(OPTIONAL) Enter the keyword mode to set the interface mode.

private-vlan

(OPTIONAL) Enter the keywords private-vlan to set the interface mode to private VLAN mode.

host

(OPTIONAL) Enter the keyword host to set the private VLAN interface to host mode.

promiscuous

(OPTIONAL) Enter the keyword promiscuous to set the private VLAN interface to promiscuous mode.

trunk

(OPTIONAL) Enter the keyword trunk to set the private VLAN interface to trunk mode.

If an IP address or VRRP group is assigned to the interface, you cannot use the switchport command on the interface. To use the switchport command on an interface, only the no ip address and no shutdown statements must be listed in the show config output.

When you enter the switchport command, the interface is automatically added to the default VLAN.

To use the switchport backup interface command on a port, first enter the switchport command. For more information, see “Configuring Redundant Links” in the Layer 2 section in the Dell EMC Networking OS Configuration Guide.
