You can set up IRF links between HPE FlexFabric 5980 switches as follows:
•
Use a QSFP28 module and fiber or a QSFP28 copper cable to connect QSFP28 ports for a
100-GE IRF physical connection.
•
Use a QSFP+ module and fiber or a QSFP+ copper cable to connect QSFP28 ports for a 40-GE
IRF physical connection.
•
Use an SFP+ module and fiber or an SFP+ copper cable to connect SFP+ ports for a 10-GE
IRF 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 QSFP28 and SFP+ ports for IRF connections on the member switches according to your
topology and connection scheme.
All the QSFP28 and SFP+ ports on the switch can be used for IRF connections.
Planning the cabling scheme
You can use QSFP28/QSFP+/SFP+ copper cables, or QSFP28/QSFP+/SFP+ transceiver modules
and fibers to connect the HPE FlexFabric 5980 switches for IRF connections.
If the switches are all in one equipment room, use QSFP28/QSFP+/SFP+ copper cables for IRF
connections. If the switches are far away from one another, use QSFP28/QSFP+/SFP+ transceiver
modules and fibers for IRF connections.
For more information about available modules and cables, see "
Appendix C Ports and LEDs
."
The following subsections describe several IRF connection schemes by using the QSFP28 copper
cables and QSFP28 transceiver modules and fibers. As a best practice, use the ring topology for IRF
connections.
Connecting the IRF member switches in one rack
Figure 33
shows an example for connecting four IRF member switches in a rack. The switches in the
ring topology (see
Figure 34
) are in the same order as connected in the rack.
