For how to configure the combo interface state, see the H3C S3100V2-52TP SwitchLayer 2—LAN Switching Configuration Guide.Planning the cabling schemeUse GE Ethernet twisted pairs, SFP IRF modules or SFP transceiver modules, and fibers to connect the IRFmember switches. If the IRF member switches are far away from one another, choose GE Ethernet twistedpairs or the SFP transceiver modules with optical fibers. If the IRF member switches are all in one rack,choose SFP IRF modules.Table 10 Lists the SFP transceiver modules and SFP IRF modules available for IRF connections.The following subsections describe several IRF connection schemes and use SFP IRF modules or SFPtransceiver modules with optical cables for example. All these schemes use a ring topology.Connecting the IRF member switches in one rackNOTE:This example uses nine switches.You can connect the IRF member switches in one rack (see Figure 26), and Figure 27 shows the IRF fabrictopology.
