5.2 Planning IRF fabric setup

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

5.2.1 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.

Step
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

See "Chapter 2 IRF" of QX-S5500G Series Ethernet Switches Configuration
Guides.
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+ DAC
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.
