Irf Physical Interface; Irf Domain Id - HP 5130 EI series Configuration Manual

To use an IRF port, you must bind a minimum of one physical interface to it. The physical interfaces
assigned to an IRF port form an aggregate IRF link automatically. An IRF port goes down only if all its IRF
physical interfaces are down.

IRF physical interface

IRF physical interfaces connect IRF member devices and must be bound to an IRF port. They forward the
IRF protocol packets between IRF member devices and the data packets that must travel across IRF
member devices.
For more information about physical interfaces that can be used for IRF links, see
requirements."

IRF domain ID

One IRF fabric forms one IRF domain. IRF uses IRF domain IDs to uniquely identify IRF fabrics and prevent
IRF fabrics from interfering with one another.
As shown in
fabric 2. Both fabrics use the LACP aggregate links between them for MAD. When a member device
receives an extended LACPDU for MAD, it checks the domain ID to see whether the packet is from the
local IRF fabric. Then, the device can handle the packet correctly.
