IRF fabric setup failure

Symptom

Two HSR6800 routers cannot form an IRF fabric.

Solution

To resolve the problem:
1. Execute the display device command on each device to verify that the devices are operating in IRF
mode and have unique IRF member IDs:
If the Chassis field is not available for a device, use the chassis convert mode irf command to

enable IRF mode for the device.
If the Chassis field is available, check the value for this field. Make sure each device has a

unique value for this field and the value must be 1 or 2. You can use the irf member renumber
command to configure the value (IRF member ID). The value takes effect after a reboot.
2. Execute the display irf configuration command to verify that IRF physical interfaces have been
bound to IRF-port 1 on one device and to IRF-port 2 on the other device.
Make sure the IRF port bindings meet the binding requirements in the virtual technologies
configuration guide for the router.
3. Verify that the IRF physical interfaces are connected correctly:
IMPORTANT:
When you connect two neighboring IRF members, connect the physical interfaces of IRF-port 1 on one
member to the physical interfaces of IRF-port 2 on the other.
a. Verify that no intermediate devices are deployed between the member devices.
b. Verify that the recommended connection media are used to connect IRF physical interfaces:
−
−
−
c. Verify that the physical IRF connections are consistent with the IRF port bindings. If there are
inconsistencies, reconfigure the IRF port bindings or reconnect the IRF physical interfaces.
4. Execute the display irf link command to verify that a minimum of one IRF link is up for the devices.
Use straight-through or crossover copper Ethernet cables to connect copper Ethernet ports
for a short-distance connection.
Use transceiver modules and fibers to connect fiber Ethernet ports for a long-distance
connection.
Make sure the transceiver modules at the two ends of an IRF link are the same type. For more
information about transceiver modules, see the device installation guide.
