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 ToR access solution for
a data center.
NOTE:
For the maximum IRF member devices supported by the S5800-EI, see the release notes that come
with the switch.
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 CLI of the master switch. IRF member switches 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 H3C S5800-EI Switch Series IRF 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.

See H3C S5800-EI Switch Series IRF Configuration Guide.
Connect physical IRF ports on switches. Use SFP+/QSFP+ transceiver
modules and fibers to connect 10-Gigabit SFP+ ports/40-Gigabit QSFP+
ports over a long distance, or use SFP+/QSFP+ cables to connect 10-Gigabit
SFP+ ports/40-Gigabit QSFP+ ports over a short distance.
All switches except the master switch automatically reboot, and the IRF fabric
is established.
