b. If the system operating mode of the chassis is different than the IRF fabric, execute
the system-working-mode command to change the system operating mode for the
chassis. The changed mode will take effect after a reboot.
11. Verify that the chassis has the same maximum number of ECMP routes as the IRF fabric:
a. Execute the display max-ecmp-num command and check the Max-ECMP-Num at the
next reboot field.
[Sysname] display max-ecmp-num
Max-ECMP-Num in use: 17
Max-ECMP-Num at the next reboot: 17
b. If the maximum number of ECMP routes of the chassis is different than the IRF fabric,
execute the max-ecmp-num command to change the number for the chassis. The changed

b. If the split followed an IRF link down event, execute the display interface command to
check port statistics for CRC errors.
