configure sflow sample-rate

configure sflow sample-rate <number>

Configures the sFlow default sampling rate.

Syntax Description

Specifies the fraction (1/number) of packets to be sampled.

The default number is 8192.

Usage Guidelines

This command configures the default sampling rate. This is the rate that newly enabled sFlow ports will

have their sample rate set to. Changing this rate will not affect currently enabled sFlow ports. 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.

Configuring a lower number for the sample rate means that more samples will be taken, increasing the

load on the switch. Do not configure the sample rate to a number lower than the default unless you are

sure that the traffic rate on the source is low.

The following command sets the sample rate to one packet out of every 16384:

configure sflow sample-rate 16384

This command was first available in ExtremeWare XOS 11.0.

Platform Availability

This command is available on all platforms.
