5.2.4 Identifying physical IRF ports on the member switches
Identify the physical IRF ports on the member switches according to your topology and
connection scheme.
Table 5-1 shows the physical ports that can be used for IRF connection and the port use
restrictions.

Candidate physical IRF ports
Requirements
QX-S5524GT-4X2Q
QX-S5548GT-4X2Q
Four fixed SFP+ ports on the
front panel
Two fixed QSFP+ ports on the
rear panel
All physical ports to be bound to an IRF port
must be the same type.
For other models, physical ports on
different interface cards can be bound to
the same IRF port.
If a QSFP+ port is split into four SFP+ ports,
the QSFP+ port cannot be used as a
physical IRF port.
