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 samp1.

<Sysname> display sampler samp1

 Sampler name: samp1

  Mode: fixed;  Packet-interval: 4;  IsNpower : Y

Table 1 Command output

Field	Description
Sampler name	Name of the sampler.
Mode	Sampling mode, including fixed mode and random mode.
Packet-interval	Sampling rate.
IsNpower	Whether the sampling rate is 2 to the nth power: ·         Y—Yes. ·         N—No.

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 you specify the n-power keyword, the sampling rate is 2 to the nth power and the value range for this argument is 1 to 13. For example, if the rate argument is set to 3, one packet is selected from 8 (2 to the 3rd power) packets in each sampling.

·          If you do not specify the n-power keyword, the sampling rate is the value of the rate argument and the value range for this argument is 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 is supported only on CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPC-GE16XP4L-E, CSPEX, and CEPC 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
