sflow flow-sampling rate

Function

The sflow flow-sampling rate command configures a flow sampling rate on an interface.

The undo sflow flow-sampling rate command restores the default flow sampling rate on an interface.

By default, the sampling rate is 8192.

Format

sflow flow-sampling rate rate { inbound | outbound }

undo sflow flow-sampling rate rate { inbound | outbound }

Parameters

Parameter	Description	Value
rate rate	Specifies a sampling rate in the format of 1/rate. rate specifies the number of packets out of which the interface will sample a packet.	The value is an integer ranging from 1 to 65535.
inbound	Specifies to get inbound direction sampling packet.	-
outbound	Specifies to get inbound direction sampling packet.	-

Usage Guidelines

Usage Scenario

To configure a flow sampling rate on an interface, run the sflow flow-sampling rate command. Setting a large sampling rate reduces the system's load but distorts the sampled data more than when a small sampling rate is set.

Precautions

sFlow cannot be configured on a channelized sub-interface with network slicing configured.

Example

# Set a flow sampling rate to 1/1000.
