Parameters

sampler-name: Specifies a sampler by its name, a case-insensitive string of 1 to 31 characters.

fixed: Specifies the fixed sampling mode. A sampler in this mode selects the first packet per sampling.

random: Specifies the random sampling mode. A sampler in this mode randomly selects a packet out of a group of packets. Which packet is selected for each sampling varies.

n-power: Specifies the sampling rate as 2 to the nth power.

rate: Specifies the sampling rate.

·     If the n-power keyword is specified, the sampling rate is 2 to the nth power, where n is value for the rate argument in the range of 0 to 13. For example, if the rate argument is set to 3, one packet is selected from 8 (2 to the 3th power) packets in each sampling.

·     If the n-power keyword is not specified, the sampling rate is the value for the rate argument in the range of 1 to 16320. For example, if the rate argument is set to 100, one packet is selected from 100 packets in each sampling.

Usage guidelines

This command takes effect on all cards.

Examples

# Create sampler abc in fixed sampling mode. Set the sampling rate to 8.

<Sysname> system-view

[Sysname] sampler abc mode fixed packet-interval 8
