IEEE 802.3ah OAM is designed to support deployment in access and IEEE 802.3ah OAM is designed to support deployment in access and
enterprise networks. In access networks, one end of a link is the enterprise networks. In access networks, one end of a link is the
CO-side, and the other is the CPE-side, and the facilities are often CO-side, and the other is the CPE-side, and the facilities are often
protected in wiring cages or closets. In such deployments, it is protected in wiring cages or closets. In such deployments, it is
often the case that the CO-side is protected from access from the CPE often the case that the CO-side is protected from access from the CPE
side. Within IEEE P802.3ah OAM, this protection from remote access side. Within IEEE P802.3ah OAM, this protection from remote access
is accomplished by configuring the CPE-side in passive mode using the is accomplished by configuring the CPE-side in passive mode using the
dot3OamMode attribute. This prevents the CPE from accessing dot3OamMode attribute. This prevents the CPE from accessing

The administrative state and mode are also read-write objects.
Disabling OAM can interrupt management activities between peer
devices, potentially causing serious problems. Setting the
dot3OamMode to an undesired value can allow access to Ethernet
monitoring, events, and functions that may not be acceptable in a
particular deployment scenario. In addition to loopback
functionality, Ethernet interface statistics and events can be
accessed via the OAM protocol, which may not be desired in some
circumstances.
OAM event configuration also contains read-write objects. These
objects control whether events are sent, and at what thresholds.
Note that the frequency of event communication is limited by the
frequency limits of Slow Protocols on Ethernet interfaces. Also, the
information available obtainable via OAM events is also available via
OAM Variable Requests. Access to this information via either OAM
events or Variable Requests is controlled by the dot3OamAdminState
and dot3OamMode objects. As mentioned previously, inadequate
protection of these variables can result in access to link
information and functions.
