Predefined user roles
network-admin
network-operator
mdc-admin
mdc-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.
chassis chassis-number slot slot-number: Specifies a card on a cluster member device. The chassis-number argument represents the member ID of the cluster 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.
cpu cpu-number: Specifies a CPU by its number.
Examples
# Display the configuration information about sampler 256.
<Sysname> display sampler 256
Sampler name: 256
Mode: Fixed; 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 in the range of 1 to 16320. One packet is selected from the specified number of packets.
Usage guidelines
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
