To set up an IRF fabric:
Step
Description
1.
Plan IRF fabric setup.
Plan the installation site and IRF fabric setup parameters:
•
Planning IRF fabric size and the installation site
•
Identifying the master switch and planning IRF member IDs
•
Planning IRF topology and connections
•
Identifying physical IRF ports on the member switches
•
2.
Install IRF member switches.
See "
Installing the switch in a 19-inch rack
."
3.
Connect ground wires and
power cords.
See "
Grounding the switch by using a grounding strip
" and
."
4.
Power on the switches.

5.
Configure basic IRF settings.
See IRF configuration in
H3C S6805&S6850&S9850 Switch Series
Virtual Technologies Configuration Guide
.
6.
Connect the physical IRF ports.
Connect the physical IRF ports on switches by using QSFP28
transceiver modules and fibers, QSFP28 fiber cables, QSFP 28
copper cables, QSFP+ transceiver modules and fibers, QSFP+ fiber
cables, or QSFP+ copper cables.
All switches except the master switch automatically reboot, and the
IRF fabric is established.
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.
