  • Page 5: Irf Overview

    IRF overview The HP Intelligent Resilient Framework (IRF) technology creates a large IRF fabric from multiple devices to provide data center class availability and scalability. IRF virtualization technology offers processing power, interaction, unified management, and uninterrupted maintenance of multiple devices.

  • Page 6: Network Topologies

    Figure 1 IRF application scenario Network topologies An IRF fabric can use a daisy-chain or ring topology. IRF does not support the full mesh topology. For information about connecting IRF member devices, see "Connecting physical IRF ports." Basic concepts This section uses Figure 2 to describe the basic concepts that you might encounter when you work with IRF.

  • Page 7: Operating Mode

    Figure 2 Two-chassis IRF fabric implementation schematic diagram In this figure, Device A and Device B form a two-chassis IRF fabric that has four MPUs (one active and three standbys) and two times the number of interface cards that a single device provides. The IRF fabric manages the physical and software resources of Device A and Device B in a centralized manner.

  • Page 8: Irf Member Id

    IRF member ID An IRF fabric uses member IDs to uniquely identify and manage its members. If two devices have the same IRF member ID, they cannot form an IRF fabric. If the IRF member ID of a device has been used in an IRF fabric, the device cannot join the fabric.

  • Page 9: Irf Physical Port

    IRF physical port IRF physical ports connect IRF member devices and must be bound to an IRF port. They forward the IRF protocol packets between IRF member devices and the data packets that must travel across IRF member devices. IRF domain ID One IRF fabric forms one IRF domain.

    Software requirements All IRF member devices must run the same system software image version. IRF size An HP 10500 IRF fabric can have up to four chassis. IRF physical port restrictions You can use 10-GE or 40-GE ports for IRF connection.

  • Page 16: Irf Link And Mpu Redundancy

    Before binding a 10-GE port in a port group to an IRF port or removing it from the IRF port, you must • shut down all the other 10-GE ports in the same group. Bring up the ports after you complete the operation. •...

  • Page 17: Multichassis Link Aggregation

    Physical ports bound to an IRF port can be located on different cards. • • HP recommends using multicard IRF links to prevent a card removal from causing an IRF split. Multichassis link aggregation For high availability, connect a downstream device to each IRF member device, and assign the links to one link aggregation group.

  • Page 18: Setup And Configuration Task List

    • Save any configuration you have made to the startup configuration file before you reboot the IRF member devices. Setup and configuration task list HP recommends the following IRF fabric setup and configuration procedure: Setup and configuration procedure Remarks (Required.) Planning the IRF fabric setup (Required.)

Preconfiguring IRF member devices in standalone mode Perform the tasks in this section on every IRF member device. These settings take effect on each member device after their operating mode changes to IRF.

  • Page 20: Binding Physical Ports To Irf Ports

    Binding physical ports to IRF ports To establish an IRF connection between two devices, you must bind at least one physical port to IRF-port 1 on one device and to IRF-port 2 on the other. For link redundancy and load sharing, bind multiple physical ports to one IRF port.

  • Page 21: Connecting Physical Irf Ports

    Connecting physical IRF ports When you connect two neighboring IRF members, connect the physical ports of IRF-port 1 on one member to the physical ports of IRF-port 2 on the other, as shown in Figure 8. For more information about IRF physical port connection restrictions, see "IRF physical port restrictions."...

  • Page 22: Accessing The Irf Fabric

    Before changing to IRF mode, use the display irf configuration command to verify that a member ID has been assigned to the device. If the MemberID field displays two hyphens (--), first assign a member ID to the device. To set the operating mode of a device to IRF mode: Step Command Remarks...
  • Page 23 One IRF fabric forms one IRF domain. IRF domain IDs prevent IRF fabrics from interfering with one another. Figure 10, Device A and Device B form IRF fabric 1, and Device C and Device D form IRF fabric 2. These fabrics have LACP MAD links between them. When a member device in one IRF fabric receives an LACP MAD packet, it looks at the domain ID in the packet to see whether the packet is from the local IRF fabric or from a different IRF fabric.

  • Page 24: Changing The Member Id Of A Device

    Changing the member ID of a device CAUTION: In IRF mode, an IRF member ID change can invalidate member ID-related settings and cause data loss. Be sure you fully understand its impact on your live network. For a successful IRF merge, you must place a device in standalone mode before renumbering it in one of the following situations: The IRF physical ports of the device are 10-GE breakout ports that are divided from a 40-GE QSFP+ •...

  • Page 27: Configuring Irf Link Load Sharing Mode

    Configuring IRF link load sharing mode On an IRF port, traffic is balanced across its physical links. You can configure the IRF port to distribute traffic based on certain criteria, including IP addresses, MAC addresses, incoming ports, or a combination of the criteria. If a criteria combination is not supported, the system displays an error message.
