43Wear an ESD wrist strap when you connect twisted pair/SFP+/SFP28/QSFP+ cables orSFP+/SFP28/QSFP+ transceiver modules and fibers. For the connection methods and precautions,see H3C Transceiver Modules and Network Cables Installation Guide.Verifying the IRF fabric setupTo verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings andconnecting IRF ports:1. Log in to the IRF fabric through the console port of any member switch.2. Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and theremote network management station can reach each other.3. Use Telnet, web, or SNMP to access the IRF fabric from the network management station. (SeeH3C S5560X-EI Switch Series Fundamentals Configuration Guide.)4. Verify that you can manage all member switches as if they were one node.5. Display the running status of the IRF fabric by using the commands in Table 8.Table 8 Displaying and maintaining IRF configuration and running statusTask CommandDisplay information about the IRF fabric. display irfDisplay all members’ IRF configurations that take effect at a reboot. display irfconfigurationDisplay IRF fabric topology information. display irf topologyNOTE:To avoid IP address collision and network problems, configure a minimum of one multi-activedetection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handlecollisions. For more information about MAD detection, see H3C S5560X-EI Switch Series IRFConfiguration Guide or H3C S5560X-EI Switch Series Virtual Technologies Configuration Guide,depending on the software version.
