6.
Connect the physical IRF ports
Connect physical IRF ports on switches. Use SFP+/QSFP+
transceiver modules and fibers for long-distance connection, or use
twisted pair/SFP+/QSFP+/QSFP+ to SFP+ 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
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 S6520XE-HI, 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 S6520XE-HI Switch Series Virtual
Technologies 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.
