Connectivity Guide

Interfaces
You can congure and monitor physical interfaces (Ethernet), port-channels, and virtual local area networks (VLANs) in Layer 2 (L2) or
Layer 3 (L3) modes.
Table 1. 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.
To re-enable a disabled interface, use the no shutdown command.
1 Congure 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
Unied port groups
In an OS10 unied port group, all ports operate in either Ethernet or Fibre Channel (FC) mode. You cannot mix modes for ports in the same
unied port group. To activate Ethernet interfaces, congure 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 congured port
prole. For more information, see S4148U-ON port proles.
