Parameters

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

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. One packet is selected from 2 to the rateth power packets in each sampling. For example, if n-power 8 is specified, one packet is selected from 256 (2 to the 8th power) packets in each sampling.

Usage guidelines

This command takes effect on all cards.

Examples

# Create sampler abc in random sampling mode. Set the sampling rate to 8 to select one packet from 256 packets in each sampling.

<Sysname> system-view

[Sysname] sampler abc mode random packet-interval  n-power 8
