49Identifying the master switch and planning IRF member IDsDetermine which switch you want to use as the master for managing all member switches in the IRFfabric.An IRF fabric has only one master switch. You configure and manage all member switches in the IRFfabric at the CLI of the master. IRF member switches will automatically elect a master. You can affect theelection result by assigning a high member priority to the intended master switch. For more informationabout master election, see H3C S12500-X Switch Series 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 connectionsConnect the IRF member switches through IRF ports, the logical interfaces for the connections betweenIRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRFport, you must bind a minimum of one physical port to it.When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port1 on one switch to the physical ports of IRF-port 2 on the other switch.A two-member IRF fabric must use the daisy chain topology.Figure 38 Daisy chain topologyIdentifying physical IRF ports on the member switchesIdentify the physical IRF ports on the member switches according to your topology and connectionscheme.On S12500-X switches, only 10-GE/40-GE/100-GE ports can be used for IRF connection.The S12500-X switches support multi-card link aggregation for IRF ports. You can bind a maximum ofeight physical ports to one IRF port.Installing IRF member switchesStep Reference1. Prepare the installation site. See "Preparing for installation."2. Mount the IRF member switches to racks. See "Installing the switch."3. Install modules on IRF member switches. See "Installing FRUs."
