Parameter descriptions
:
Delete
: Check to delete the entry. It will be deleted during the next save.
FMI ID
: The
FlowMeterInstance
parameter is an index into the FlowMeterTable.
CIR
: The
FlowMeterCIR
parameter contains an integer value that represents the CIR value for the flow meter, in
bit/s.
CBS
: The
FlowMeterCBS
parameter contains an integer value that represents the CBS value for the flow meter,
in octets.
EIR
: Excess Information Rate is the average rate (in bytes per unit of time), in excess of the CIR, up to which the
network may transfer frames without any performance objectives.
EBS
: (Excess Burst Size) defines a limit on the maximum number of information units (e.g., bytes) available for a
burst of frames sent at the interface speed to remain EIR-conformant.
CF
: Coupling flag (CF) allows the choice between two modes of operation of the rate enforcement algorithm.
CM
: Color mode (CM) indicates whether the "color-aware" or "color-blind" property is employed by the
bandwidth profile.
Color Aware
: Algorithm considers the color indication of incoming frames. Incoming frames without a
color indication get a default color prior to entering the meter. Frames are never “promoted”; an
incoming yellow frame is never changed to green.
Color Blind
: Algorithm ignores the color indication (if any) of incoming frames. Effectively all incoming
frames are assumed to start out green.
Drop On Yellow
: Flow-meter-instance boolean drop-on-yellow = // r-w.
Mark RED Enable
: The
FlowMeterMarkAllFramesRedEnable
parameter contains a Boolean value that indicates
whether the MarkAllFramesRed function is enabled (TRUE) or disabled (FALSE).
Mark Red
: The
FlowMeterMarkAllFramesRed
parameter contains a Boolean value that indicates whether, if the
MarkAllFramesRed
function is enabled, all frames are to be discarded (TRUE) or not (FALSE).
