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 is 1–10.

port-group node/slot/port-group

2 Activate the unied 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.

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

All physical, Ethernet and port-channel interfaces use a single MAC address and, by default, 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.

You can 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 multiple (two or more) VLANs.

A trunk interface carries VLAN trac that is tagged using 802.1q encapsulation. If an access interface receives a packet with an 802.1q tag

in the header that is dierent from the access VLAN ID, it drops the packet.
