13SolutionTo resolve the problem:1. Verify that the number of member devices does not exceed the upper limit.When you are adding a new member device to an existing IRF fabric or merging IRF fabrics,use the display irf command to identify the number of member devices in the IRF fabrics. If thetotal number of member devices exceeds the upper limit, the IRF setup will fail.2. Verify that the member devices can join the same IRF fabric.An S6800 switch can form an IRF fabric only with devices in the same series. In addition, theS6800 switches are divided into two groups. Only S6800 switches in the same group can jointhe same IRF fabric.The following S6800 switches are in one group:{ The S6800-2C-FC switch.{ The S6800-54HF switch.{ The S6800-54HT switch.{ The S6800 switches with the following product codes:− LS-6800-2C-H1.− LS-6800-4C-H1.− LS-6800-32Q-H1.− LS-6800-54QF-H1.− LS-6800-54QF-H3.− LS-6800-54QT-H1.− LS-6800-54QT-H3.The S6800 switches with the following product codes are in one group:{ LS-6800-2C.{ LS-6800-4C.{ LS-6800-32Q.{ LS-6800-54QF.{ LS-6800-54QT.3. Verify that the member ID of each member device is unique:a. Execute the display irf command to view the member ID of each member device.b. Use the irf member renumber command to assign a unique member ID to each member.− If you are adding a new member device to an existing IRF fabric, assign the memberdevice a member ID that is not being used in the IRF fabric.− If you are merging IRF fabrics, make sure each member device in these IRF fabrics hasa unique member ID.4. Verify that the IRF port bindings and physical IRF link connections are correct:a. Execute the display irf configuration command, and check the IRF-Port1 and IRF-Port2fields for IRF port bindings.b. Verify that the physical interfaces bound to IRF ports are IRF capable. You can use10GBase-T Ethernet ports, SFP+, QSFP+, or QSFP28 ports for IRF links. If there arebinding errors, reconfigure the IRF port bindings.c. Verify that the IRF physical interfaces are correct connected. When you connect twoneighboring IRF members, you must connect the physical interfaces of IRF-port 1 on onemember to the physical interfaces of IRF-port 2 on the other.
