Identifying Irf Physical Ports On The Member Switches - H3C S5560S-EI Series Installation Manual

You connect the IRF member switches through IRF ports, the logical interfaces for the connections
between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port
2. To use an IRF port, you must bind a minimum of one physical port to it.
When connecting two neighboring IRF member switches, you must connect the physical ports of
IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.
The switch can form an IRF fabric only with switches from the same switch series. For the physical
ports that can be used for IRF connections on each switch model and the restrictions for using the
ports, see Table
highest speeds. For example, a 10-GE port must operate at 10 Gbps. A GE port must operate at 1
Gbps.

Identifying IRF physical ports on the member switches

Identify the IRF physical ports on the member switches according to your topology and connection
scheme.
Table 4-1 shows the physical ports that can be used for IRF connection and the port use restrictions.
