  • Page 34: Planning Irf Topology And Connections

    Planning IRF topology and connections You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. 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.

  • Page 35: Identifying Physical Irf Ports On The Member Switches

    Figure4-3 IRF fabric in ring topology You can set up IRF links between S6850-56HF-CP switches as follows: • Use a QSFP28 module and fiber or a QSFP28 cable to connect QSFP28 ports for a 100-GE IRF physical connection. • Use a QSFP+ module and fiber or a QSFP+ cable to connect QSFP28 ports for a 40-GE IRF physical connection.
  • Page 36 The following subsections describe several IRF connection schemes by using the QSFP28 cables and QSFP28 transceiver modules and fibers. As a best practice, use the ring topology for IRF connections. Connecting the IRF member switches in one rack Figure4-4 shows an example for connecting four IRF member switches in a rack. The switches in the ring topology (see Figure4-5) are in the same order as connected in the rack.
