Figure 1. S4148U-ON unified port groups To enable Ethernet interfaces in a unified port group: 1 Configure a unified port group in CONFIGURATION mode. Enter 1/1 for node/slot. The port-group range is 1-10. port-group node/slot/port-group 2 Activate the unified port group for Ethernet operation in PORT-GROUP mode. mode Eth {100g-1x | 50g-2x | 40g-1x | 25g-4x | 10g-4x} • 10g-4x - Split a QSFP28 or QSFP+ port into four 10G interfaces. • 25g-4x - Split a QSFP28 port into four 25G interfaces. • 40g-1x - Set a QSFP28 port to 40G mode (use with a QSFP+ 40GE transceiver). • 50g-2x - Split a QSFP28 port into two 50G interfaces. • 100g-1x - Reset a QSFP28 port to 100G mode. 3 Return to CONFIGURATION mode. exit 4 Enter Ethernet Interface mode to configure other settings.

From L2 mode, you can configure switching and L2 protocols, such as VLANs and spanning-tree protocol (STP) on an interface. You can enable L2 switching on a port interface in access or trunk mode. By default, an interface is configured in access mode. Access mode allows L2 switching of untagged traffic on a single VLAN (VLAN 1 is the default). Trunk mode enables L2 switching of untagged traffic on the access VLAN, and tagged traffic on multiple (two or more) VLANs. A trunk interface carries VLAN traffic that is tagged using 802.1q encapsulation. If an access interface receives a packet with an 802.1q tag in the header that is different from the access VLAN ID, it drops the packet. 72 Interfaces
