SFP+ port
2. 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 HPE 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.
• On the HPE 5900AF-48G-4XG-2QSFP+ and 5900AF-48G-4XG-2QSFP+ TAA switches, SFP+ ports numbered 49, 50,
51, and 52 form one group. • On the HPE 5900AF-48XGT-4QSFP+ and 5900AF-48XGT-4QSFP+ TAA switches, the
1/10-GE ports are grouped by port number in ascending order, starting from one. Every four 1/10-GE ports form one
group.
A common practice is to use one 1/10-GE port or SFP+ port group for IRF connections, and bind every two 1/10-GE port or
SFP+ ports in the group to an IRF port for increased bandwidth and availability.
