Configuring IRF
To ensure a successful IRF setup, read the configuration restrictions and guidelines carefully before
you connect and set up an IRF fabric.
General restrictions and configuration guidelines
This section describes the restrictions and configuration guidelines you must follow.
Software requirements
All IRF member switches must run the same system software image version.
IRF link redundancy
The HPE 5800 and 5820X switches support up to four physical ports for an IRF port.
IRF physical port restrictions and cabling requirements
Candidate IRF physical ports include the SFP+ ports on the front panel and the SFP+ ports on
expansion interface cards. Expansion interface cards must be purchased separately.
For long-distance IRF connections, use the SFP+ transceiver modules in Table 1 . For short-distance
IRF connections, use the SFP+ cables in Table 2 .
