Whether this event occurred locally (local(1)), or was received from the OAM peer via Ethernet OAM (remote(2)). ::= { cdot3OamEventLogEntry 5 } SYNTAX Unsigned32 MAX-ACCESS read-only STATUS current DESCRIPTION If the event represents a threshold crossing event, the two objects cdot3OamEventWindowHi and cdot3OamEventWindowLo form an unsigned 64-bit integer yielding the window over which the value was measured for the threshold crossing event (for example, 5, when 11 occurrences happened in 5 seconds while the threshold was 10). The two objects are combined as: cdot3OamEventLogWindow = ((2^32) * cdot3OamEventLogWindowHi) + cdot3OamEventLogWindowLo Otherwise, this value is returned as all F's (2^32 - 1) and adds no useful information. REFERENCE "[802.3ah], 30.3.6.1.37 and 57.5.3.2.
