44Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identifyand manage 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 connectionsbetween IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port2. To use an IRF port, you must bind a minimum of one physical port to it.When 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.A two-member IRF fabric must use the daisy chain topology.Figure 51 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 H3C S9800 switches, only 10-GE/40-GE/100-GE ports can be used for IRF connection.The H3C S9800 switches support multi-card link aggregation for IRF ports. You can bind up to eightphysical 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."Configuring basic IRF settingsAfter you install the IRF member switches, power on the switches, and log in to each IRF memberswitch (see "Accessing the switch for the first time") to configure their member IDs, member priorities,and IRF port bindings.Follow these guidelines when you configure the switches:• First configure the member IDs, member priorities, and IRF port bindings for the IRF memberswitches, save the configuration, connect the member switches, and change the operatingmode of the switches to IRF mode.• Assign the master switch higher member priority than any other switch.
