dot3OamErrSymPeriodWindowLo

Module: DOT3-OAM-MIB

OID (symbolic): DOT3-OAM-MIB::dot3OamErrSymPeriodWindowLo

OID (numeric): 1.3.6.1.2.1.158.1.5.1.2

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: The two objects dot3OamErrSymPeriodWindowHi and dot3OamErrSymPeriodWindowLo together form an unsigned 64-bit integer representing the number of symbols over which this threshold event is defined. This is defined as

dot3OamErrSymPeriodWindow = ((2^32)*dot3OamErrSymPeriodWindowHi) + dot3OamErrSymPeriodWindowLo

If dot3OamErrSymPeriodThreshold symbol errors occur within a window of dot3OamErrSymPeriodWindow symbols, an Event Notification OAMPDU should be generated with an Errored Symbol Period Event TLV indicating that the threshold has been crossed in this window.

The default value for dot3OamErrSymPeriodWindow is the number of symbols in one second for the underlying physical layer.

What is dot3OamErrSymPeriodWindowLo?

This read-write value is the low-order 32 bits of the 64-bit symbol-count window used for the Errored Symbol Period event, defaulting to the number of symbols transmitted in one second on the physical layer. An admin tunes this (with the Hi companion object) to widen or narrow the sampling window used to flag a bad-symbol-rate event.

Examples
