Interfaces
You can configure and monitor physical interfaces (Ethernet), port-channels, and virtual local area networks (VLANs) in Layer 2
(L2) or Layer 3 (L3) modes.
Table 11. Interface types
Interface type Supported Default mode Requires creation Default status
Ethernet (PHY) L2, L3 unset No no shutdown enabled
Management N/A N/A No no shutdown enabled
Loopback L3 L3 Yes no shutdown enabled
Port-channel L2, L3 unset Yes no shutdown enabled
VLAN L2, L3 L3 Yes, except default no shutdown enabled
Configuration notes
All Dell EMC PowerSwitches except MX-Series, S4200-Series, S5200 Series, and Z9332F-ON:
● To avoid loops in an L2 network with statically configured port channels, keep the no switchport configuration on an
interface after you remove its port-channel configuration using the no interface port-channel command.
● On a S4148-ON switch, 10GBASE-T transceiver cannot operate at 100M or 1G speed.
Ethernet interfaces
Ethernet port interfaces are enabled by default. To disable an Ethernet interface, use the shutdown command. Use the show
interface status command to view the status of the interfaces.
NOTE:
Linux operation or commands such as shutdown or no-shutdown and ip-address that are run against the interface is
not reflected in the CLI.
To reenable a disabled interface, use the no shutdown command.
1. Configure an Ethernet port interface from Global CONFIGURATION mode.
interface ethernet node/slot/port[:subport]
2. Disable and reenable the Ethernet port interface in INTERFACE mode.
