Sflow Sampling-Rate - H3C SR6600 Command Reference Manual

random: Specifies the random sampling mode. For example, if the packet sampling rate is set to 4000,
the device may sample one packet from the first 4000 packets, two from the next 4000 packets, and
none from the third 4000 packets, randomly. But generally the device samples one packet from 4000
packets on the average.
Usage guidelines
This command is supported on physical Ethernet interfaces only, instead of logical interfaces (Ethernet
subinterfaces and VLAN interfaces) and network management interfaces.
Examples
# Specify the fixed sample mode on GigabitEthernet 4/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 4/0/1

Parameters
rate: Specifies the number of packets out of which flow sampling will sample a packet on the interface.
The value range is 1000 to 500000.
Usage guidelines
This command is supported on Ethernet interfaces only, instead of logical interfaces (such as Ethernet
subinterfaces and VLAN interfaces) and network management interfaces.
The bigger the value of the interval argument, the lower the sampling rate. On the other hand, the smaller
the value, the higher the sampling rate.
Examples
# Set GigabitEthernet 4/0/1 to sample a packet out of 4000 packets.
