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

NOTE:
The following figures use the SFP+ ports on S5120V2-28P-HPWR-LI switches as an example. For

Identifying IRF physical ports on the member switches

Identify the IRF physical ports on the member switches according to your topology and connection
scheme.
To uses physical ports on a switch in the S5500V3-SI switch series (excluding the S5500V3-24P-SI
and S5500V3-48P-SI) for IRF connection, obey the following rules as a best practice:
•
Use four highest numbered SFP+ ports if the switch has six SFP+ ports.
•
Use two highest numbered SFP+ ports if the switch has four SFP+ ports.
With these ports as IRF physical ports, the IRF packets are placed in queues of higher forwarding
priorities, ensuring smooth IRF packet forwarding in the event of large amounts of data packets and
avoiding IRF splitting and other faults.
Table 15 shows the physical ports that can be used for IRF connection and the port use restrictions.
