Interfaces
You can configure and monitor physical interfaces (Ethernet), port-channels, and VLANs in L2 or 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 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, enter the shutdown command.
To re-enable a disabled interface, enter 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 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.
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.
