1GE mode: 1GE is supported only on SFP+ ports; 1GE is not supported on QSFP+ and QSFP28 ports 25-26.
Breakout interfaces: Use the interface breakout command in Conguration mode to congure 4x10G, 4x25G, and 2x50G breakout
interfaces.
To view the ports that belong to each port group, use the show port-group command.
S4148U-ON port proles
S4148U-ON port proles determine the available front-panel unied and Ethernet ports and supported breakout interfaces. In the port
prole illustration, blue boxes indicate the supported Ethernet port modes and breakout interfaces. Brown boxes indicate the supported
Fibre Channel port modes and breakout interfaces. Blank spaces indicate ports and speeds that are not available. Unied port groups are
numbered 1 to 10.
S4148U-ON unied port modes—SFP+ ports 1-24 and QSFP28 ports 25-26 and 29-30:
10GE is an SFP+ port in Ethernet mode or a 4x10G breakout of a QSFP+ or QSFP28 port in Ethernet mode.
25GE is a 4x25G breakout of a QSFP28 Ethernet port.
40GE is a QSFP+ or QSFP28 Ethernet port that uses QSFP+ 40GE transceivers.
50GE is a 2x50G breakout of a QSFP28 Ethernet port.
100GE is a QSFP28 Ethernet port.
4x8GFC are breakout interfaces in an SFP+ or QSFP28 FC port group.
2x16GFC are breakout interfaces (subports 1 and 3) in an SFP+ or QSFP28 FC port group.
4x16GFC are breakout interfaces in a QSFP28 FC port group.
1x32GFC (subport 1) are breakout interfaces in a QSFP28 FC port group.
S4148U-ON Ethernet modes—QSFP+ ports 27-28 and SFP+ ports 31-54:
10GE mode is an SFP+ 10GE port or a 4x10G breakout of a QSFP+ port.
40GE mode is a QSFP+ port.
For example, all S4148U-ON activate support 10G speed on unied ports 1-24 and Ethernet ports 31-54, but only profile-1 and
profile-2 activate QSFP+ ports 27-28 in 40GE mode with 4x10G breakouts. Similarly, all S4148U-ON proles activate 8GFC speed on
unied ports 1-24, but only profile-1, profile-2, and profile-3 activate 2x16GFC in port groups 1-6. In QSFP28 port groups,
profile-1 and profile-2 support 1x32GFC; profile-3 and profile-4 support 4x16GFC.
