An IRF port handles link down and link up events, as follows: When the IRF link changes from up to down, the port does not immediately report the change to the •...

  • Page 20: Irf Member Description

    Usage guidelines By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC address. Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On a switched LAN, the bridge MAC address must be unique.

The port-number argument represents the index of the port on the member switch, and must be 1 or 2. Usage guidelines To set up an IRF link between two switches, you must enter IRF port view to bind physical ports to the IRF port used by each switch for IRF connection.

    destination-mac: Distributes packets across IRF member links based on destination MAC address. source-ip: Distributes packets across IRF member links based on source IP address. source-mac: Distributes packets across IRF member links based on source MAC address. Usage guidelines On an IRF port that has multiple links, traffic is balanced across its physical links. You can configure the IRF port to distribute traffic based on source IP address, destination IP address, source MAC address, destination address, or a combination of them.

  • Page 26: Mad Arp Enable

    Plan the IRF setup, including the IRF fabric topology, IRF fabric size, member ID assignment, and bindings of physical ports and IRF ports. Change the IRF member ID of each switch to make sure they are unique in the IRF fabric. Connect the physical ports between neighboring switches and make sure that the peer ports can reach each other.

  • Page 27: Mad Bfd Enable

    Default ARP MAD is disabled. Views VLAN interface view Default command level 3: Manage level Usage guidelines You can set up ARP MAD links between neighbor IRF members or more commonly, between each IRF member device and an intermediate device. When you configure ARP MAD, follow these guidelines: If an intermediate device is used, you can use common data links as ARP MAD links.

  • Page 28: Mad Enable

  • Page 29: Mad Exclude Interface

    LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate H3C device that also supports LACP MAD packets. When you use LACP MAD, follow these guidelines: The intermediate device must be an H3C device that support extended LACP for MAD. • •...

  • Page 30: Mad Ip Address

    IRF physical ports and those manually configured to not shut down. If a port must be kept in up state for special purposes such as Telnet connection, exclude it from the shutdown action. To avoid problems, H3C recommends excluding only the one used for Telnet for the management purpose.

  • Page 31: Mad Restore

    To avoid anomalies, do not assign the BFD MAD-enabled VLAN interface a common IP address, for example, an IP address configured with the ip address command or a VRRP virtual IP address. The master tries to establish BFD sessions with other members by using its MAD IP address as the source IP address: If the IRF fabric is integrated, only the MAD IP address of the master is effective.

  • Page 32: Port Group Interface

    The S5800 and S5820X switches support up to four physical ports for an IRF port. Make sure the physical ports at both ends of an IRF link are using the same operating mode. For an aggregate IRF link, H3C recommends configuring the same operating mode for all physical IRF ports at both ends.
