26When connecting two neighboring IRF member switches, you must connect the physical ports ofIRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.The S6520-42QF-EI and S6520-52QF-EI switches can provide 10-GE and 40-GE IRF connectionsthrough SFP+ ports and QSFP+ ports, respectively.The S6520-48S-EI switch can provide 10-GE IRF connections through SFP+ ports.You can bind several ports of the same type to an IRF port for increased bandwidth and availability.Figure 30 and Figure 31 show the topologies of an IRF fabric made up of three S6520-EI switches.The IRF port connections in the two figures are for illustration only, and more connection methodsare available.Figure 30 IRF fabric in daisy chain topologyFigure 31 IRF fabric in ring topologyIdentifying physical IRF ports on the member switchesIdentify the ports to be used for IRF connections on the member switches according to your topologyand connection scheme.All ports on the front panel of the switch can be used for IRF connections.Follow these guidelines when you identify 1/10-GE Ethernet ports and SFP+ ports to be used for IRFconnections:IRF-port1IRF-port2IRF-port1IRF-port1IRF-port2IRF-port212312 3
