The set of ports for which a frame with a specific
unicast address will be flooded in the event that it
has not been learned. It also specifies the set of
ports on which a specific unicast address may be dynamically
learned. The dot1qTpFdbTable will have an equivalent
entry with a dot1qTpFdbPort value of '0' until this
address has been learned, at which point it will be updated
with the port the address has been seen on. This only
applies to ports that are members of the VLAN, defined
by dot1qVlanCurrentEgressPorts. The default value of
this object is a string of ones of appropriate length.
The value of this object MUST be retained across
reinitializations of the management system.
