NETGEAR 8800 Chassis Switch CLI Manual Default The default polling interval is 20 seconds. Usage Guidelines Each sFlow statistics counter is polled at regular intervals, and this data is then sent to the sFlow collector. This command is used to set the polling interval. To manage CPU load, polling for sFlow enabled ports are distributed over the polling interval, so that all ports are not polled at the same instant. For example, if the polling interval is 20 seconds and there are twenty counters, data is collected successively every second. Specifying a poll interval of 0 (zero) seconds disables polling. Example The following command sets the polling interval to 60 seconds: configure sflow poll-interval 60 configure sflow ports sample-rate configure sflow ports sample-rate Description Configures the sFlow per-port sampling rate. Syntax Description portlist number Specifies a list of ports. Specifies the fraction (1/number) of packets to be sampled. Default The default number is 8192, unless modified by the configure sflow sample-rate command. Usage Guidelines This command configures the sampling rate on a particular set of ports and overrides the system-wide value set in the configure sflow sample-rate command. The rate is rounded off to the next power of two, so if 400 is specified, the sample rate is configured as 512. The valid range is 1 to 536870912. All ports on the switch or same I/O module are sampled individually. Example The following command sets the sample rate for the ports 4:6 to 4:10 to one packet out of every 16384: Chapter 8.
