Setting this object to enabled (1) enables eavesdrop prevention on this port. When eavesdrop prevention is active, the repeater compares unicast destination addresses of packets being transmitting out this port with the port's authorized address list. The repeater jams/garbles those packets whose destination addresses do not appear in the port's authorized address list. The length of the garbled packet is the same as the length of the original packet. Packets with multicast or broadcast destination addresses are not affected by eavesdrop prevention. If no authorized addresses are assigned to this port in erptrSecurityPortAddrTable when this object equals enabled(1), an implementation may optionally enforce eavesdrop prevention based upon the (dynamically changing) last source address seen (as indicated by rptrAddrTrackLastSourceAddr or rptrAddrTrackNewLastSrcAddress). Otherwise, an implementation may simply not actively enforce eavesdrop prevention on a port with no assigned authorized addresses. Setting this object to disabled (2) disables eavesdrop prevention on this port. Note: The default value for this object is disabled (2). Note: The state of this object is preserved when the repeater undergoes a power-up reset.
