Sampler commands

display sampler

Use display sampler to display configuration information for a sampler.

Syntax

In standalone mode:

display sampler [ sampler-name ] [ slot slot-number ]

In IRF mode:

display sampler [ sampler-name ] [ chassis chassis-number slot slot-number ]

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 0. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the device, which is fixed at 0. If you do not specify an IRF member device, this command displays sampler configuration information for the master device. (In IRF mode.)

Examples

# Display the configuration information about sampler 256.

<Sysname> display sampler 256

 Sampler name: 256

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

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: Sets the sampling rate to 2 to the power of n.

rate: Specifies the sampling rate. If the n-power keyword is not specified, one packet is selected from rate packets in each sampling. The value range for rate argument is 1 to 65536. For example, if rate argument is set to 100, one packet is selected from 100 packets in each sampling. If the n-power keyword is specified, one packet is selected from 2 to the rateth power packets in each sampling. The value range for n-power keyword is 1 to 16. For example, if n-power 8 is specified, one packet is selected from 256 (2 to the 8th power) packets in each sampling.

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
