  • Page 8: Irf Configuration

    At present, the S7500E Series Ethernet Switches support an IRF virtual device of two members, which means you can use two S7500E series switches to form an IRF virtual device: one operates as the master and the other operates as the slave.

  • Page 9: Application

    devices can be aggregated, and thus the reliability of the IRF virtual device is increased through link redundancy. Powerful network expansion capability. By adding member devices, the number of IRF ports and network bandwidth of an IRF virtual device can be easily expanded. Each member device has its own CPU and they can process and forward protocol packets independently.

  • Page 10: Basic Concepts

    Basic Concepts Figure 1-2 IRF implementation schematic diagram As shown in Figure 1-2, Device A and Device B are physically connected. After you perform necessary configurations on them, they form an IRF virtual device, which has four switching and routing processing units (SRPUs) (one active SRPU and three standby SRPUs) and two interface cards.
  • Page 11 Physical IRF port Physical ports used for IRF connection on devices are called physical IRF ports. On the S7500E series, you can configure a 10 GE optical port as a physical IRF port. By default, a 10 GE optical port functions as a common service port and forwards data traffic. When bound with an IRF port, it acts as an IRF physical port and forwards packets among member devices.

  • Page 12: Working Process

    IRF port or, to realize link backup, can bind to multiple physical IRF ports (known as aggregate IRF port). The S7500E series uses 10 GE optical ports as physical IRF ports. You can connect physical IRF ports with fibers. Fibers connect physical devices located very far from each other and provide flexible application.

  • Page 13: Topology Collection

    Figure 1-5 Physical connections of IRF virtual device The orange line in the figure represents the IRF link, which is different from a common Ethernet link. An IRF link can be composed of either one physical cable or multiple physical links. Topology Collection Each member exchanges hello packets with the directly connected neighbors to collect topology of the IRF virtual device.

  • Page 14: Irf Virtual Device Management And Maintenance

    During the mergence, IRF election is held, and role election rules are followed. You need to manually reboot the members of the loser side, and then they join the winner side as slaves. IRF Virtual Device Management and Maintenance After role election, an IRF virtual device is established: all member devices operate as one virtual device, and all resources on the member devices are possessed by this virtual device and managed by the master.

  • Page 15: Irf Multi-Active Detection Mechanism

    Therefore, to make the IRF virtual device operate normally, you need to make sure that the link state is normal and connect the IRF ports of two devices correctly before configuring an IRF virtual device; after the establishment of the IRF virtual device, configure necessary anti-attack policies to ensure device safety.

  • Page 16: Irf Virtual Device Configuration Task List

    For information about LACP, see Ethernet Link Aggregation Configuration in the Layer 2 - LAN Switching Configuration Guide; for information about BFD, see BFD Configuration in the High Availability Configuration Guide. When an IRF virtual device is partitioned, the system disables all service ports on the member device of the IRF virtual device that transits to recovery state (that is equal to executing the shutdown command on these ports).

  • Page 17: Switching Operating Mode

    Task Remarks Specifying the reserved ports Optional Failure recovery Optional Accessing the Master Required Accessing an IRF Virtual Device Accessing a Slave Optional After establishing an IRF virtual device, you are recommended to configure the MAD detection function to avoid the influences to the network caused by accidental partition of the IRF virtual device. Switching Operating Mode The device can operate in either IRF mode or standalone mode.

    To do… Use the command… Remarks Enter system view system-view — Required Switch the operating mode of the chassis convert mode irf By default, the device operates device to IRF mode in standalone mode. The device automatically reboots as soon as you confirm the operation of switching the operating mode.

  • Page 19: Specifying A Priority For A Member Device

    1. Configuring IRF Ports The S7500E series uses 10 GE optical ports, which are on the SRPU, or on SC, SD, or EB interface card, as physical IRF ports to perform IRF connection. For more information about LPUs providing 10 GE optical ports, see the related information in the H3C S7500E Series Ethernet Switches Installation Manual.

  • Page 20: Specifying The Preservation Time Of Irf Bridge Mac Address

    You can bind multiple physical IRF ports to one IRF port by executing the port group interface command for multiple times. In addition, the S7500E series allows you to bind multiple physical IRF ports on different LPUs to one IRF port.

  • Page 21: Setting The Delay Time For The Link Layer To Report A Link-Down Event

    Preserve for six minutes: After the master leaves, the bridge MAC address will not change within six minutes. If the master does not come back after six minutes, the IRF virtual device will use the bridge MAC address of the newly elected master as its bridge MAC address. Preserve permanently: No matter whether the master leaves the IRF virtual device or not, the bridge MAC address of the IRF virtual device remains unchanged.

    To do… Use the command… Remarks Set the delay time for the link Optional layer to report a link-down event irf link-delay interval The default value is 200 ms. of an IRF virtual device Do not set the time interval to a very long time; otherwise, the IRF virtual device cannot be aware of the topology changes in time and thus services will be recovered slowly.

    Accessing an IRF Virtual Device Accessing the Master After an IRF virtual device is formed, you can access the console of the IRF virtual device from the AUX or console port of any member device. Create a Layer 3 Ethernet interface, and configure an IP address for it, and make sure that the interface and the user terminal are routable to each other.
