  • Page 34: Planning Irf Fabric Setup

    You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see HP FlexFabric 7900 Switch Series IRF Configuration Guide. Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID.
  • Page 35 When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch. You can create an IRF fabric in daisy chain topology or more reliable ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology.
  • Page 36: Determining Physical Irf Ports On The Member Switches

    The following subsections use QSFP+ cables and QSFP+ transceiver modules and fibers as examples to describe several IRF connection schemes. All these schemes use a ring topology. HP recommends that you connect IRF member switches using a ring topology.
  • Page 37: Configuring Basic Irf Settings

    Configuring basic IRF settings After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see HP FlexFabric 7900 Switch Series Fundamentals Configuration Guide) to configure their member IDs, member priorities, and IRF port bindings.
  • Page 38: Connecting The Physical Irf Ports

    Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the remote network management station can reach each other. Use Telnet, Web, or SNMP to access the IRF fabric from the network management station. (See HP FlexFabric 7900 Switch Series Fundamentals Configuration Guide.) Verify that you can manage all member switches as if they were one node.
  • Page 39: Maintenance And Troubleshooting

    Use display commands to examine the configuration for configuration errors or examine statistics for exceptions. If any configuration error is found, re-configure the switch or restore the factory-default settings. For more information, see HP FlexFabric 7900 Switch Series Fundamentals Configuration Guide.
