Physical Connections
Physical port
To make an IRF virtual device operate normally, physically connect the member devices. For the
S5820X and S5800 series switches, use SFP+ ports on the front panel or SFP+ ports on an interface
card as physical IRF ports.
For details of SFP+ ports and interface cards used on different device models, refer to
H3C S5800
Series Ethernet Switches Installation Manual
and
H3C S5820X Series Ethernet Switches Installation
Manual
.
When you use SFP+ ports, select SFP+ transceivers and optical fibers or SFP+ cables described in
Table 1-1
for connecting member devices.

Use SFP+ transceivers with optical fibers when members are far from each other to increase network
flexibility; use SFP+ cables when members are all in one equipment room.

Physical IRF ports can be used for connecting members and transmitting data traffic. To establish an
IRF virtual device, bind physical IRF ports to IRF ports.
Correspondence between an IRF port and a physical IRF port
The connection of IRF ports is based on that of physical IRF ports; therefore, bind an IRF port to
physical IRF port(s). An IRF port can be bound to one physical IRF port or, to back up links and expand
bandwidth, bound to multiple physical IRF ports (aggregated as an aggregate IRF port).
The following describes the correspondence between an IRF port and physical IRF port(s) on the
S5800 series and S5820X series:
