Upgrade to a release that contains a fix for CR xos0063134, (at this moment unknown).When you encounter the problem, delete the static fdb entry and create it again.
In most cases this must be done twice as the first delete does not delete the fdb from all hardware slots.
Do below twice
delete fdbentry <mac> vlan <vlan>
create fdbentry <mac> vlan <vlan> port <port>
delete fdbentry 00:00:00:00:11:11 vlan test
create fdbentry 00:00:00:00:11:11 vlan test port 1:1
