Enabling Mac-lockdown-with-timeout along with Netlogin on the port, and disabling or disconnecting the port, flushes the locked down entries immediately, without waiting for the lock-down timer to expire.
Environment
All EXOS based products Firmware: 15.3.x, 15.5.3.x, 15.6.2.x
Cause
Disabling or disconnecting the port with mac-lockdown-timeout enabled altogether with Netlogin flushes the MAC entry from FDB, thus losing the mac-lock-down entry.
Resolution
Fixed in the following FW releases: 15.3.5 15.5.4 15.6.2-patch1
