The ATM address of the designated LES. Note that
setting this object will have the side effect of
reinitializing the LES and consequently dropping all
clients connected to it. If this object is not
specified at row creation time then the LES will
choose a value for itself and attempt to register with
the switch with that value. If an address is
specified which is not acceptable to the switch then
the lesOperStatus will remain inactive until an
acceptable address is set.
