Hi Kyoung,
This looks like a glitch where bfd messages logged even when BFD is not enabled.
Request to open a TAC case.

Do share the in case the following

• show tech-support
• Also the bfd logs from the device when observed.

Note: Min Exos version to be at recommended version.

Regards,
Anil

We also see these messages since a few weeks on ten X670 switches with XOS 16.2.2.4.
