Planning IRF fabric setup

This section describes issues that an IRF fabric setup plan must cover.

Planning IRF fabric size and the installation site

Choose switch models and identify the number of required IRF member switches, depending on the
user density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals
the total switching capacities of all member switches.
Plan the installation site depending on your network solution as follows:
•
Place all IRF member switches in one rack for centralized high-density access.
•
Distribute the IRF member switches in different racks to implement the top-of-rack (ToR) access
solution for a data center.
As your business grows, you can add member switches into the IRF fabric to increase the switching
capacity without any topology change or replacement.

Identifying the master switch and planning IRF member IDs

Determine which switch you want to use as the master for managing all member switches in the IRF
fabric. An IRF fabric has only one master switch. You configure and manage all member switches in
the IRF fabric at the command line interface of the master switch.
NOTE:
IRF member switches will automatically elect a master. You can affect the election result by
assigning a high member priority to the intended master switch. For more information about master
election, see IRF configuration in H3C S6805 & S6825 & S6850 & S9850 Switch Series Virtual
Technologies Configuration Guide.
Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify
and manage its members, and you must assign each IRF member switch a unique member ID.

All switches except the master switch automatically reboot, and the
IRF fabric is established.
