Connecting physical IRF ports

When you connect two neighboring IRF members, connect the physical ports of IRF-port 1 on one
member to the physical ports of IRF-port 2 on the other, as shown in
Follow these guidelines on selecting transceiver modules and cables:
Use XFP transceiver modules and fibers to connect XFP ports.
•
• Use SFP+ transceiver modules and fibers for long-distance connection, or use SFP+ cables to
connect SFP+ ports for short-distance connection.
When connecting XFP or SFP+ ports, connect the transmit port of an XFP or SFP+ transceiver
•
module at one end to the receive port of a XFP or SFP+ transceiver module at the other end.
Use QSFP+ transceiver modules and fibers for long-distance connection, or use QSFP+ cables to
•
connect QSFP+ ports for short-distance connection.
The transceiver modules at the two ends of an IRF link must be the same type.
•
For more information about transceiver modules, see the switch installation guide.
IMPORTANT:
No intermediate devices are allowed between neighboring members.
Figure 9 Connecting IRF physical ports
Connect the switches into a daisy chain topology or a ring topology, which is more reliable (see
10). In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain
topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services.
To use the ring topology, you must have at least three member switches.
