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.

and power cords.

4.
Power on the switches. N/A
5.
Configure basic IRF
settings.

H3C S7500E-XS Switch Series IRF Configuration Guide
.
6.
Connect the physical
IRF ports.
Connect the physical IRF ports on switches. Use SFP+/QSFP+ transceiver
modules and fibers for long-distance connection. Use twisted pair cables or
SFP+/QSFP+ DAC cables for short-distance connection.
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 the 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.
