The desired authorized MAC address for this port.
This can be either a regular station address to
configure a specific address, or it can be one of
the following special values to specify the
address learning method:
FFFF-FFFF-FFFE: learnOnce. First source MAC
address heard on this port becomes the
authorized address. Setting this value
initiates learning of a new authorized
address. When a new authorized address is
learned, it will be stored in nonvolatile
memory. This variable will return
learnOnceConditionally to a GET operation
after it has been set to this value.
FFFF-FFFF-FFFD: learnOnceConditionally. This
option will initiate learning of a new
authorized address only if the previous
hubSecPtSecurityAddress was set to a
specific address or learnContinuous. No
action will be performed if the previous
value was already learnOnceConditionally.
FFFF-FFFF-FFFC: learnContinuous. Any address
heard becomes the new authorized address.
When a new address is learned, it may
cause an alarm, but it does not store
anything in nonvolatile memory.
