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 44. 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

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.

To re-enable 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 re-enable the Ethernet port interface in INTERFACE mode.

shutdown

no shutdown

Disable Ethernet port interface

OS10(config)# interface ethernet 1/1/1

OS10(conf-if-eth1/1/1)# shutdown

Enable Ethernet port interface

OS10(config)# interface ethernet 1/1/1

OS10(conf-if-eth1/1/1)# no shutdown

Unified port groups

In an OS10 unified port group, all ports operate in either Ethernet or Fibre Channel (FC) mode. You cannot mix modes for ports

in the same unified port group. To activate Ethernet interfaces, configure a port group to operate in Ethernet mode and specify

the port speed. To activate Fibre Channel interfaces, see Fibre Channel interfaces.

S4148U-ON

On the S4148U-ON switch, the available Ethernet and Fibre Channel interfaces in a port group depend on the currently

configured port profile. For more information, see S4148U-ON port profiles.
