NOTE:
x
You can establish an IRF fabric that comprises different A10500 switch models.
x
The member switches in an IRF must use the same version of system software image.
2.
Select LPUs that can provide 10-GE optical ports.
NOTE:
x
The A10500 switch series requires 10-GE optical ports for IRF connection.
x
For more information about the LPUs, see the chapter “Appendix B FRUs and compatibility matrixes.”
3.
Select transceiver modules (XFP or SFP+) and fibers for long-haul IRF connection, or select SFP+
cables for short-haul IRF connection. For more information about transceiver modules and SFP+
cables, see the chapter “Appendix B FRUs and compatibility matrixes.”
4.
Plan the installation site.
Planning the IRF network
Plan the IRF network and identify the role, member ID, physical IRF ports of each member switch.
Identifying the master switch
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.
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
HP
A10500 Switch Series IRF Configuration Guide.
Planning member IDs
An IRF fabric uses member IDs to uniquely identify and manage its members.
Assign each IRF member switch a unique member ID before connecting them to form an IRF fabric.
Identifying the physical IRF ports on the member switches
Determine which 10-GE ports to use for IRF connection depending on the bandwidth and reliability
requirements.
The A10500 switch series supports link aggregation and cross-card aggregation for IRF ports. You can
bind up to eight physical ports to one IRF port.
