Feature Description
Note: On the SFBRM1040-1xx redundant models, there
can be only one (1) OAM session at a time—the
OAM enabled port is user selected. Port 2 fiber is
the default port.
Operation
Administration and
Maintenance (OAM,
IEEE 802.3ah-2004
standard) The Device implements the IEEE OAM 802.3ah
standard for troubleshooting and remote management.
This product implements OAM on both the fiber and
twisted pair interfaces. It implements the following
OAM features:
• Discovery
• Remote Loop Back
• Exchange of configuration information and remote
firmware upgrades with organization specific PDUs
• Link status failure indication
The Device implements the draft-ietf-hubmib-efm-mib
(EFM OAM MIB). Use the version provided on the CD.
Critical Event (OAM, When the link on the other port fails, the Device sends an
OAM critical event signal to its peer, indicating the fault
condition.
IEEE 802.3ah-2004
standard)
Discovery (OAM, An active-state Device initiates OAM communications
by sending PDUs across the link connected to an OAM
enabled port. The Device at the other end (if OAM
capable) responds to the request from the active Device
by establishing an OAM communications channel.
IEEE 802.3ah-2004
standard)
Event Notification with
Log In (OAM, An OAM link event notifies its OAM peer of any symbol
or frame errors that occurred on its link. The window
used for error monitoring, along with the threshold value
are configurable. At the end of the window, if the errors
are greater than or equal to the threshold value, an OAM
event notification is sent to its peer. If the threshold is set
to zero, then at the end of each window an event
notification is sent—this acts more like an asynchronous
update of the link statistics.
IEEE 802.3ah-2004
standard)
