  • Page 3: Introduction

    For complete information, see IRF configuration guide for the switch. Hardware requirements An H3C S6890 switch can form an IRF fabric only with devices in the same series. Software requirements All IRF member devices must run the same system software version.

  • Page 4: Irf Physical Interface Requirements

    IRF physical interface requirements Use the following ports on the S6890 switch for IRF links: • SFP+ ports. • QSFP28 ports. Connecting IRF ports When you connect two neighboring IRF members, connect the physical interfaces of IRF-port 1 on one member to the physical interfaces of IRF-port 2 on the other. Licensing requirements For a license-based feature to run correctly on an IRF fabric, make sure the licenses installed for the feature on all member devices are the same.
