Determining physical IRF ports on the member switches
Determine the physical IRF ports on the member switches according to your topology and connection
scheme.
You can use 40-GE ports on the switch for IRF connection.
The switch supports multi-card link aggregation for IRF ports. You can bind up to eight physical ports to
one IRF port.
Planning the cabling scheme
Use QSFP+ transceiver modules and fibers for long-distance connection, or use QSFP+ cables to connect
QSFP+ ports for short-distance connection.
For more information about transceiver modules available for the switch, see "
Appendix B FRUs and
compatibility matrixes ."
The following subsections use QSFP+ cables and QSFP+ transceiver modules and fibers as examples to
describe several IRF connection schemes. All these schemes use a ring topology. HP recommends that
you connect IRF member switches using a ring topology.
Connecting the IRF member switches in one rack
Connect the IRF member switches (4 switches in this example) in a rack as shown in Figure 34 . The
switches in the ring topology (see Figure 35 ) are in the same order as connected in the rack.
