Binding Physical Interfaces To Irf Ports - HP FlexFabric 5700 series Configuration Manual

Figure 9 Connecting IRF physical interfaces
Connect the devices into a daisy-chain topology or a ring topology. A ring topology is more reliable
(see Figure 10). In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in
daisy-chain topology. Rather, the IRF fabric changes to a daisy-chain topology without interrupting
network services.
To use the ring topology, you must have a minimum of three member devices.

Binding physical interfaces to IRF ports

When you bind physical interfaces to IRF ports, follow these guidelines:
Follow the restrictions in
•
You must always shut down a physical interface 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 interface bound to an IRF port, you can execute only the description, flow-interval,
priority-flow-control, and shutdown commands. For more information about these commands, see Layer
2—LAN Switching Command Reference.
