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 a card by its slot number. If you do not specify a card, this command displays sampler configuration information for the active MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on 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 card. If you do not specify a card, this command displays sampler configuration information for the global active MPU. (In IRF mode.)

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 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 not specified, one packet is selected from rate 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. 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 form 8 packets in each sampling.

<Sysname> system-view

[Sysname] sampler abc mode random packet-interval  8
