Figure 47 IRF fabric in ring topology
You can set up IRF links between HPE 5950 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.
•
Use a 100G QSFP28 to 4 x 25G SFP28 cable to connect a QSFP28 port to four 25G SFP28
ports.
•
Use a QSFP+ module and fiber or a QSFP+ cable to connect QSFP+ ports for a 40-GE IRF
connection.
•
Use an SFP28 module and fiber or an SFP28 cable to connect SFP28 ports for a 25-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, QSFP+, and SFP28 ports for IRF connections on the member switches
according to your topology and connection scheme.
All the QSFP28, QSFP+, and SFP28 ports on the HPE 5950 switches can be used for IRF
connections.
When you select ports in a port group for IRF links, you must use all or none of the ports in the group
for IRF links. The ports can be bound to different IRF ports.
The port grouping rules are as follows:
•
The HPE FlexFabric 5950 48SFP28 8QSFP28 Switch (JH402A) has two port ranges. Ports
numbered 1 to 24 are in one range and ports numbered 33 to 56 are in the other range. In each
