Known Affected Releases 6.5.0

Description (partial)

FTD running enforcing traffic based on SGT (IP any any rule, only SGT is used as criteria).

Enforcement is working correctly, FMC correctly shows connection event with Source SGT (see screenshot), however, direct syslog (post-6.3. connection event logging directly from FTD) do not show SGT in the log message.

FW engine-debug for a connection:
