RC-LINK-OAM-MIB Table View

This table contains the primary controls and status for the
OAM capabilities of an Ethernet-like interface.  There will be
one row in this table for each Ethernet-like interface in the
system that supports the OAM functions defined in [802.3ah].

rcLinkOamEntry row .1.3.6.1.4.1.2272.1.82.1.1

An entry in the table that contains information on the
Ethernet OAM function for a single Ethernet like interface.
Entries in the table are created automatically for each
interface supporting Ethernet OAM. The status o…

This table contains information about the OAM peer for a
particular Ethernet-like interface.  OAM entities communicate
with a single OAM peer entity on Ethernet links on which OA
is enabled and operating properly.  There is one entry in this
table for each entry in the rcLinkOamTable for which information
on the peer OAM entity is available.

This table contains controls for the loopback state of the
local link as well as indicates the status of the loopback
function.  There is one entry in this table for each entry in
rcLinkOamTable that supports loopback functionality (where
rcLinkOamFunctionsSupported includes the loopbackSupport bit
set).
          
Loopback can be used to place the remote OAM entity in a state
where every received frame (except OAMPDUs) is echoed back
over the same interface on which they were received.  In this
state, at the remote entity, 'normal' traffic is disabled as
only the looped back frames are transmitted on the interface.
Loopback is thus an intrusive operation that prohibits normal
data flow and should be used accordingly.

An entry in the table, containing information on the loopback
status for a single Ethernet-like interface. Entries in the
table are automatically created whenever the local OAM entity
supports loopback capabilities. T…

This table contains statistics for the OAM function on a
particular Ethernet-like interface.  There is an entry in the
table for every entry in the rcLinkOamTable.
          
The counters in this table are defined as 32-bit entries to
match the counter size as defined in [802.3ah].  Given that
the OA protocol is a slow protocol, the counters increment at
a slow rate.
