Candidate physical IRF ports
Requirements
•
S5560-30S-EI
•
S5560-54S-EI
•
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 have the same data
rate.
•
For the S5560-54QS-EI, SFP+ ports
49 to 52 form a group. When an
SFP+ port is bound to an IRF port,
other SFP+ ports in the same port
group cannot be used as service
ports, and vice versa. Each QSFP+
port is a group.
•
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
virtual SFP+ ports, the QSFP+ port
cannot be used as a physical IRF
port.

Planning the cabling scheme
Use twisted pair cables, SFP+/QSFP+ cables, or SFP+/QSFP+ transceiver modules and fibers to
connect the IRF member switches. If the IRF member switches are far away from one another, choose
