    When you are working on a live network, make sure you understand the potential impact of every command on your network. This document assumes that you have basic knowledge of H3C IRF. General restrictions and guidelines When you set up and configure an IRF fabric, follow the restrictions and guidelines in this section.

  • Page 4: Software Requirements For Irf

    Software requirements for IRF All IRF member devices must run the same software image version. Make sure the software auto- update feature is enabled on all member devices. IRF fabric size An CR16000-F IRF fabric supports a maximum of two member devices. IRF port connection When you connect 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 (see...

To avoid single points of failure, use multichassis link aggregations to connect the IRF fabric to the downstream and upstream devices.
