Saving configuration to the next-startup
configuration file
Save the running configuration before converting to the IRF mode. The mode change requires a reboot,
which can cause all unsaved settings to be lost.
Perform the following task in any view:

Connecting physical IRF ports
A good practice is to use 10-GE fiber ports as physical IRF ports.
When you connect two neighboring IRF members, connect the physical ports of IRF-port 1 on one
member to the physical ports of IRF-port 2 on the other, as shown in Figure 11 .
If copper Ethernet ports are used, use straight-through or crossover copper Ethernet cables to connect
them.
If fiber Ethernet ports are used, install transceiver modules and use fibers to connect them. For more
information about transceiver modules, see the device installation guide.
To connect two IRF member devices through SFP+ ports, you can also use an SFP+ cable.
