Figure 1. S4148U-ON unied port groups

To enable Ethernet interfaces in a unied port group:

1 Congure a unied port group in CONFIGURATION mode. Enter 1/1 for node/slot. The port-group range depends on the switch.

port-group node/slot/port-group

2 Activate the unied port group for Ethernet operation in PORT-GROUP mode. To activate a unied port group in Fibre Channel mode,

see Fibre Channel interfaces. The available options depend on the switch.

mode Eth {100g-1x | 50g-2x | 40g-1x | 25g-4x | 10g-4x}

• 100g-1x — Reset a port group to 100GE mode.

• 50g-2x — Split a port group into two 50GE interfaces.

• 40g-1x — Set a port group to 40GE mode for use with a QSFP+ 40GE transceiver.

• 25g-4x — Split a port group into four 25GE interfaces.

• 10g-4x — Split a port group into four 10GE interfaces.

3 Return to CONFIGURATION mode.

4 Enter Ethernet Interface mode to congure other settings. Enter a single interface, a hyphen-separated range, or multiple interfaces

separated by commas.

L2 mode conguration

Each physical Ethernet interface uses a unique MAC address. Port-channels and VLANs use a single MAC address. By default, all the

interfaces operate in L2 mode. From L2 mode you can congure switching and L2 protocols, such as VLANs and Spanning-Tree Protocol

(STP) on an interface.

Enable L2 switching on a port interface in Access or Trunk mode. By default, an interface is congured in Access mode. Access mode

allows L2 switching of untagged trac on a single VLAN (VLAN 1 is the default). Trunk mode enables L2 switching of untagged trac on

the Access VLAN, and tagged trac on one or more VLANs.
