You can set up IRF links between S6850-56HF-IM switches by using a QSFP28 module and fiber to
connect QSFP28 ports for a 100-GE IRF physical connection.
You can bind several ports to an IRF port for increased bandwidth and availability.

Identifying physical IRF ports on the member switches

Identify the physical ports for IRF connections on the member switches according to your topology
and connection scheme.
All the QSFP28 ports on the switch can be used for IRF connections.

Planning the cabling scheme

You can use QSFP28 transceiver modules and fibers to connect the S6850-56HF-IM switches for
IRF connections.
The following subsections describe several IRF connection schemes by using the QSFP28
transceiver modules and fibers. As a best practice, use the ring topology for IRF connections.
Figure4-4 shows an example for connecting four IRF member switches. The switches in the ring
topology (see Figure4-5) are connected in the same order.
