Configuring IRF

To ensure a successful IRF setup, read the configuration restrictions and guidelines carefully before you
connect and set up an IRF fabric.

General restrictions and configuration guidelines

Software requirements

All IRF member switches must run the same software image version.

IRF physical port restrictions and binding requirements

To connect blade switches in different chassis into an IRF fabric, you must use the SFP+ and QSFP+ ports
on the switch front panel.
To connect blade switches in the same chassis into an IRF fabric, you must use the downlink 10-GE
Ethernet ports on the switch rear panel. These ports are invisible to users and do not require physical
cabling.
Selecting transceiver modules and cables for connecting blade switches in different chassis
When you select transceiver modules and cables, follow these guidelines:
• Use SFP+/QSFP+ transceiver modules and fibers for long-distance connection.
Use SFP+/QSFP+ cables to connect SFP+/QSFP+ ports for short-distance connection.
•
• Make sure the transceiver modules at the two ends of an IRF link are the same type.
For more information about transceiver modules, see the switch installation guide.
QSFP+ port restrictions
You can use a QSFP+ port as an IRF physical port, or use the using tengige command to split a QSFP+
port into four 10-GE interfaces.
The following restrictions apply to these 10-GE interfaces:
You must use all or none of the four 10-GE interfaces as IRF physical ports. The four interfaces can
•
be bound to different IRF ports.
Before you bind a 10-GE interface to an IRF port or remove it from the IRF port, you must shut down
•
all the 10-GE interfaces of the 40-GE port. If any of the interfaces is in up state, the bind or remove
action will fail.
SFP+ port restrictions
When you use the SFP+ ports on the switch front panel as IRF physical ports, follow these guidelines:
The SFP+ ports are grouped by port index into two 4-port groups. One port group contains ports
•
5, 6, 9, and 10. The other port group contains ports 7, 8, 1 1, and 12. If you use one port in a group
for IRF connection, you must also use all the other ports in the group for IRF connection. However,
you can bind them to different IRF ports.
