Step Description
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 " and " Connecting the power cords ."
4. Power on the switches.
N/A
5. Configure basic IRF settings.
See H3C S6805 & S6825 & S6850 & S9850 Switch Series Virtual
Technologies Configuration Guide .
6. Connect the physical IRF ports.
Connect the physical IRF ports on switches. Use QSFP28/QSFP+
transceiver modules and fibers for connections over long distances.
Use QSFP28/QSFP+ cables for connections over short distances.
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
Determine 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.
You can use switches of the same series or use switches of both the S6850 and S9850 series to form
an IRF fabric.
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.
NOTE:
IRF member switches will 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 S6805 & S6825 & S6850 & S9850 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.
