5.2.4 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.
All the SFP+ and QSFP+ ports on the QX-S6600 Series can be used for IRF connections.
Follow these guidelines when you identify SFP+ ports to be used for IRF connections:
On a QX-S6648XP-6Q, the SFP+ ports are grouped by port number in ascending

order, starting from one. Every four SFP+ ports form one group.
On a QX-S6648XT-6Q, the 1/10-GE Ethernet ports are grouped by port number in

ascending order, starting from one. Every four 1/10-GE Ethernet ports form one group.
A 1/10-GE Ethernet port/SFP+/QSFP+ port can be bound to an IRF port or operate as
