Identifying Physical Irf Ports On The Member Switches; Planning The Cabling Scheme - H3C S6850-56HF-CP Manual

Figure4-3 IRF fabric in ring topology
You can set up IRF links between S6850-56HF-CP switches as follows:
•
Use a QSFP28 module and fiber or a QSFP28 cable to connect QSFP28 ports for a 100-GE
IRF physical connection.
•
Use a QSFP+ module and fiber or a QSFP+ cable to connect QSFP28 ports for a 40-GE IRF
physical connection.
You can bind several ports to an IRF port for increased bandwidth and availability.
When you use a QSFP+ DAC cable to connect a pair of peer IRF physical interfaces, the peer
interfaces must both be fixed ports or both be ports on expansion modules that are the same model.

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/QSFP+ cables, or QSFP28/QSFP+ transceiver modules and fibers to connect
the S6850-56HF-CP switches for IRF connections.
If the switches are all in one equipment room, choose QSFP28/QSFP+ cables for IRF connections. If
the switches are far away from one another, choose QSFP28/QSFP+ transceiver modules and fibers
for IRF connections.
