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.

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.
