Commands for Status Monitoring and Statistics
configure sflow max-cpu-sample-limit
configure sflow max-cpu-sample-limit <rate>
Description
Configures the maximum number of sFlow samples handled by the CPU per second.
Syntax Description
Default
The default value is 2000 samples per second.
Usage Guidelines
This command configures the maximum number of samples sent to the CPU per second. If this rate is
exceeded, the internal sFlow CPU throttling mechanism kicks in to limit the load on the CPU. Every
time the limit is reached, the sample rate is halved (the value of
number
in the
configure sflow
sample-rate <number>
or
configure sflow ports <portlist> sample-rate <number>
command
is doubled), on the slot on which maximum number of packets are received.
This effectively doubles the sampling frequency of all the ports on that slot with a sub-sampling factor
of 1. The sampling frequency of ports on that slot with a sub-sampling factor greater than 1 will not
change; the sub-sampling factor is halved so the that the same rate of samples are sent from that port.
The maximum CPU sample rate is based on the total number of samples received from all the sources.
The valid range is 100 to 5000 samples per second.
Example
The following command specifies that the sFlow maximum CPU sample rate should be set to 4000
samples per second:
configure sflow max-cpu-sample-limit 4000
