Parameters

sampler-name: Specifies a sampler by its name, a case-insensitive string of 1 to 31 characters. If you do not specify a sampler, this command displays configuration information for all samplers.

slot slot-number: Specifies the slot number of the device, which is fixed at 1.

Examples

# Display the configuration information about sampler 256.

<Sysname> display sampler 256

 Sampler name: 256

  Mode: random;  Packet-interval: 8; IsNpower: Y

Parameters

sampler-name: Specifies a sampler by its name, a string of 1 to 31 characters. In versions earlier than Release 5212P06, the sampler name is case insensitive. In Release 5212P06 and versions, the sampler name is case sensitive. When other service modules reference a sampler, the sampler name is case-sensitive.

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

If you execute this command multiple times and specify different sampler names, multiple samplers are configured. If only the letter case of sampler names is different, the sampler name in the first configuration is used, and the sampling rate in the most recent configuration is used.

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
