BIG-IQ validates the MTU with a max of 9000, however there are some versions and platforms that support greater values. See this SOL: https://support.f5.com/kb/en-us/solutions/public/6000/300/sol6399.html When BIG-IQ attempts discovery of a device with a VLAN MTU greater than 9000 import will fail.
BIG-IQ cannot import BIG-IP into ADC and cannot manage ADC for those devices.
BIG-IP with VLAN MTU greater than 9000 is configured.
Reduce the MTU to 9000 or lower.
