Planning IRF fabric setup

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.
Description
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

Planning the cabling scheme

Connect physical IRF ports on switches. Use SFP+ transceiver modules and
fibers to connect 10-Gigabit SFP+ ports over a long distance, or use SFP+
the physical
cables to connect 10-Gigabit SFP+ ports over a short distance.
All switches except the master switch automatically reboot, and the IRF fabric
is established.
Before you install the switch, make sure:
 You have read ―Preparing for installation‖ carefully
and the installation site meets all the requirements.
