config flow_meter
Description
This command is used to configure the flow-based metering function. The metering function supports
three modes: single rate two color, single rate three color, and two rate three color. The access rule must
be created before the parameters of this function can be applied.
For the single rate two color mode, users may set the preferred bandwidth for this rule, in Kbps, and
once the bandwidth has been exceeded, overflowing packets will either be dropped or have a drop
precedence set, depending on the user configuration.
For single rate three color mode, users need to specify the committed rate, in Kbps, the committed burst
size, and the excess burst size.
For the two rate three color mode, users need to specify the committed rate in Kbps, the committed
burst size, the peak rate and the peak burst size.
There are two cases for mapping the color of a packet: Color-blind mode and Color-aware mode. In the
Color-blind case, the determination for the packet’s color is based on the metering result. In the Color-
aware case, the determination for the packet’s color is based on the metering result and the ingress
DSCP.
When color-blind or color-aware is not specified, color-blind is the default mode.
The green color packet will be treated as the conforming action, the yellow color packet will be treated
as the exceeding action, and the red color packet will be treated as the violating action.
The replace DSCP action can be performed on packets that conform (GREEN) and packets that do not
conform (YELLOW and RED). If drop YELLOW/RED is selected, the action to replace the DSCP will
not take effect.
