maintenance of multiple devices. This book describes IRF concepts and guides you through the IRF setup procedure. Hardware compatibility An HP 6125XLG blade switch can form an IRF fabric only with devices in the same series. IRF benefits IRF provides the following benefits: • Simplified topology and - HP 6125XLG | R2306-HP 6125XLG Blade Switch IRF Configuration Guide - Page 6
supported. For information about connecting IRF member devices, see "Connecting physical IRF ports." Basic concepts This section describes the basic concepts you might encounter when you work with IRF. IRF member roles IRF numbers and file paths to uniquely identify interfaces and files in an IRF - HP 6125XLG | R2306-HP 6125XLG Blade Switch IRF Configuration Guide - Page 7
IRF port An IRF port is a logical interface for the connection between IRF member devices. Every IRF-capable device supports two IRF ports. The IRF ports are named IRF-port n/1 and IRF-port n/2, where n is the member ID of the switch. The two IRF ports are referred to as "IRF-port 1" and "IRF-port - HP 6125XLG | R2306-HP 6125XLG Blade Switch IRF Configuration Guide - Page 8

In contrast, BFD MAD, ARP MAD, and ND MAD do not compare the number of members in fabrics.

QSFP+ port restrictions You can use a QSFP+ port as an IRF physical port, or use the using tengige command to split a QSFP+ port into four 10-GE interfaces. The following restrictions apply to these 10 - HP 6125XLG | R2306-HP 6125XLG Blade Switch IRF Configuration Guide - Page 18
IRF ports. • Before you bind a downlink 10-GE Ethernet port to an IRF port or remove it from the IRF port, you must shut down all the other downlink 10-GE ports on the switch rear panel. Connecting IRF ports When you connect two neighboring IRF members, connect IRF-port 1 on one member to IRF-port - HP 6125XLG | R2306-HP 6125XLG Blade Switch IRF Configuration Guide - Page 19
