Overview
In order to avoid overloading and congestion of information which passes
network, Signamax series switches provide rate limitation based on port
input direction. It means that it processes limitation to the total rate of
port receiving direction. The flow with exceeding rate will be dropped. To
configure the parameter as the bandwidth threshold (Kbit
，
64K is the
minimal granularity) and the burst flow (byte).
Basic Commands
Command Description Confg mode
Rate-limit rate burst-size To configure the rate limitation
of a port; the granularity of
the rate is 64K and the unit of
the burst-size is byte.
Config-port-*/*
no rate-limit To cancel the rate limitation of
a port
Config-port-*/*
rate-limit rate burst-size
When users configuring the command, the input parameters may be
different with the practical value configured successfully. Because the
drive adjusts the value input by users according to the chip. The final
verity value of the rate is an integer multiple of 64.
When the input value is not 64, the drive adjusts the value as a minimal
integer multiple of 64 which are greater than the present value. The
revised value of Burst-size is an integer multiple of 4096. The average
rate of the command at the port inputting direction is the value of the
rate. The bursting flow actually is the depth of the token barrel. It means
the allowed biggest flow size of each bursting.
Syntax Description
rate To configure the bandwidth threshold with 64k
step length and its value range is among
0~16777152.
burst-size The range of bursting flow is among
4096~16773120.
