Parameters
length: Specifies the maximum number of bytes that can be copied, in the range of 18 to 512. As a
best practice, use the default value.
Examples
# Set the maximum number of bytes to 60 for flow sampling to copy per packet on GigabitEthernet
1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] sflow flow max-header 60
sflow sampling-mode
Use sflow sampling-mode to specify a flow sampling mode.
Use undo sflow sampling-mode to restore the default.
Syntax
sflow sampling-mode random
undo sflow sampling-mode
Views
Layer 2 Ethernet interface view
Predefined user roles

Parameters
random: Specifies the random sampling mode. For example, if the packet sampling interval is set to
4000 (by using the sflow sampling-rate command), the device samples packets randomly as
follows:
• The device might sample one packet from the first 4000 packets.
• The device might sample multiple packets from the next 4000 packets.
• The device might sample no packets from the third 4000 packets.
However, the device samples one packet from 4000 packets on average.
Examples
# Specify random flow sampling mode on GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] sflow sampling-mode random

sflow sampling-rate
Use sflow sampling-rate to enable flow sampling and specify the number of packets out of which
flow sampling will sample a packet.
Use undo sflow sampling-rate to disable flow sampling.
