Saving Configuration To The Next-Startup Configuration File; Connecting Irf Physical Ports - HP 12500 SERIES Configuration Manual

Step
1. Enter system view.
2. Enable enhanced IRF mode.
Saving configuration to the next-startup
configuration file
Save the running configuration before connecting IRF physical links. To avoid data loss, also save
the running configuration during the configuration procedure. A master/standby switchover can
cause all settings that have not been saved to be lost.
Perform the following task in any view:

Connecting IRF physical 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
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.

Connect the devices into a daisy chain topology or more reliably, a ring topology (see
ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain
