range, the ports are grouped by port number in order, starting from the lowest number. Each
group contains four ports.
•
On an LSWM124TG2H (JH450A) module, the ports numbered 1 to 24 are grouped by port
number in order, starting from the lowest number. Each group contains four ports.
•
On an LSWM116Q module (JH405A), the ports are grouped by port number in order, starting
from 1. Each group contains two ports.
•
The four 25-GE breakout interfaces of a 100-GE port are in one port group. To split a 100-GE
port, use the

command.
•
Except the LSWM116Q module, if you use a 40-GE or 100-GE port that is not split for IRF links,
no grouping restrictions exist.
Planning the cabling scheme
You can use QSFP28/QSFP28 to SFP28/QSFP+/SFP28 cables, or QSFP28/QSFP+/SFP28
transceiver modules and fibers to connect the HPE switches for IRF connections.
If the switches are all in one equipment room, choose QSFP28/QSFP28 to SFP28/QSFP+/ SFP28
cables for IRF connections. If the switches are far away from one another, choose
QSFP28/QSFP+/SFP28 transceiver modules and fibers for IRF connections.
For more information about cables, see "
."
The following subsections describe several IRF connection schemes by using the QSFP28 cables
and QSFP28 transceiver modules and fibers. As a best practice, use the ring topology for IRF
connections.
