The global status of the new learned address notification
feature.
When this object is set to enabled(1), the agent will generate
etsysIetfBridgeDot1qFdbNewLearnedAddr notifications for each
new address learned on ports that have their corresponding
etsysIetfBridgeDot1dBasePortNewLearnedAddrTrap object set to
enabled(1).
If etsysIetfBridgeDot1dBasePortNewLearnedAddrTrap is set
to disabled(2) for all ports then setting this object to
enabled(1) will not have any effect.
When this object is set to disabled(1), the agent will not
generate any etsysIetfBridgeDot1qFdbNewLearnedAddr
notifications.
