Chapter 21 QSFP+ Port Split and
Combination Configuration
21.1 Introduction to QSFP+ Port Split and Combination
Configuration
QSFP+ port can be used as a single 40GE port and it also can be splited into 4 10GE
SFP+ ports to improve the port density, decrease the user cost and increase flexibility of
networks. For example, QSFP+ port of Ethernet1/1/1 is 40GE as default, it can be split into 4
10GE SFP+ ports according to need of Ethernet1/1/1, Ethernet1/1/2, Ethernet1/1/3 and
Ethernet1/1/4. The SFP+ ports split support the same configuration and feature as the ordinary
SFP+ physical port. QSFP+ port need the dedicated one-to-four wire to connect after split.
If user needs larger bandwidth, the 4 10GE ports can be combined to a 40GE port for
using. After combination, the wire should be changed as one-to-one wire. The description of
wire is shown in the relevant manual.
QSFP+ port split and combination configuration must be saved and restart the switch,
then it will be effective.
21.2 QSFP+ Port Configuration
QSFP+ port configuration task list is as below:
1. Enter port configuration mode
2. QSFP+ port split/combination configuration
3. Configuration retained
4. Restart switch
1. QSFP+ port split/combination configuration
Command
Explanation
Global Mode
hardware profile mode 4x10G
no hardware profile mode 4x10G
Split the appointed QSFP+ interface from
40GE port mode into 4 SFP+ 10GE port
modes; the no command combines the 4
SFP+ 10GE ports to 1 40GE port.
