Sampler commands
display sampler
Use display sampler to display configuration information for a sampler.
Syntax
display sampler [ sampler-name ] [ slot slot-number ]
Views
Any view
Predefined user roles
network-admin
network-operator
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 an IRF member device by its member ID. If you do not specify a member device, this command displays sampler configuration information for the master device.
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.
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
Each port can only use one sampler. If the sampler name, sampling rate, or sampling target specified by different services is inconsistent, the sampler cannot be shared on the same port.
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
