26NOTE:IRF member switches will automatically elect a master. You can affect the election result by assigning ahigh member priority to the intended master switch. For more information about master election, see theH3C S3100V2-52TP Switch IRF Configuration Guide.Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify andmanage its members, and you must assign each IRF member switch a unique member ID.Planning IRF topology and connectionsYou 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 IRFfabric changes to a daisy chain topology without interrupting network services.You connect the IRF member switches through IRF ports. An IRF port is a logical interface for the internalconnection between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 andIRF-port 2. An IRF port is activated when you bind a physical port to it.When connecting IRF member switches, you must connect the physical ports of IRF-port1 on one switchto the physical ports of IRF-port2 on its neighbor switch.The S3100V2-52TP switches can provide IRF connections through the GE Ethernet ports and GE SFP ports,and you can bind several GE ports to an IRF port for increased bandwidth and availability.NOTE:• Figure 24 and Figure 25 show the topologies for an IRF fabric made up of three S3100V2-52TPswitches.• The IRF port connections in the two figures are for illustration only, and more connection methods areavailable.Figure 24 IRF fabric in daisy chain topologyIRF-port1IRF-port2IRF-port1IRF-port21 2 3123
