Identifying physical IRF ports on the member switches
Identify the SFP+ or QSFP+ ports to be used for IRF connections on the member switches according to
your topology and connection scheme.
Table 8 de
scribes the physical ports available for establishing IRF connections:

SFP+ port
You can bind several ports of the same type to an IRF port for increased bandwidth and availability.
1/10-GE ports and SFP+ ports are grouped as follows. When a 1/10-GE port or SFP+ port is bound to
an IRF port, the other ports in the same group will not be used as a service port, and vice versa.
• On the HP 5920AF-24XG, 5920AF-24XG TAA, 5900CP-48XG-4QSFP+, 5900CP-48XG-4QSFP+
TAA, 5900CP-48XG-4QSFP+8Gb FC B-F, 5900AF-48XG-4QSFP+, and 5900AF-48XG-4QSFP+
TAA switches, the SFP+ ports are grouped by port number in ascending order, starting from one.
Every four SFP+ ports form one group.
