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 [ cpu cpu-number ] ]

In IRF mode:

display sampler [ sampler-name ] [ chassis chassis-number slot slot-number [ cpu cpu-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 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 information for the global active MPU. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number.

Examples

# Display the configuration information about sampler samp1.

<Sysname> display sampler samp1

 Sampler name: samp1

  Mode: fixed;  Packet-interval: 4; 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 specified, the sampling rate is 2 to the nth power, where n is value for the rate argument in the range of 0 to 13. For example, if the rate argument is set to 3, one packet is selected from 8 (2 to the 3th power) packets in each sampling.

·     If the n-power keyword is not specified, the sampling rate is the value for the rate argument in the range of 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

(In standalone mode.) (In IRF mode.) This command takes effect on all 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
