The remote MAC address detected on the bridge port
identified by to this entry. Setting this object results
in an attempt to create a new entry in the table. Since
the value of a3ComSysBridgePortAddressIndex is determined

using the values of a3ComSysBridgePortAddressTypeIndex and
a3ComSysBridgePortAddressPortIndex can be used to determine the
address index assigned to the newly added address entry.
