Binding Physical Ports To Irf Ports - HP 6125XLG Configuration Manual

Figure 10 Connecting IRF physical ports
Connect the devices into a daisy chain topology or a ring topology. A ring topology is more reliable
(see Figure 1
chain topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network
services.
To use the ring topology, you must have at least three member devices.

Binding physical ports to IRF ports

When you bind physical ports to IRF ports, follow these guidelines:
Follow the restrictions in
•
You must always shut down a physical port before binding it to an IRF port or removing the binding.
•
Start the shutdown operation on the master and then the member device that has the fewest number
of hops from the master.
On a physical port bound to an IRF port, you can execute only the shutdown, description,
priority-flow-control, and flow-interval commands. For more information about these commands, see
Layer 2—LAN Switching Command Reference.
To bind physical ports to IRF ports:
Step
1. Enter system view.
1). In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy
