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.
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.
rate: Specifies the sampling rate. One packet is selected from rate packets in each sampling.
Usage guidelines
The total number of samplers varies by device model.
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 from 8 packets in each sampling.
<Sysname> system-view
[Sysname] sampler abc mode random packet-interval 8
