Parameters
instance instance-id
: Specifies an sFlow instance by its ID in the range of 1 to 4. The default
ID for an sFlow instance is 1. If you do not specify an sFlow instance, this command specifies sFlow
instance 1 for flow sampling.
collector-id : Specifies an sFlow collector by its ID. The value range for this argument is 1 to 10.
Usage guidelines
This command enables the device to send flow sampling information on an interface to the specified
sFlow collector.
On an interface, one sFlow instance has only one sFlow collector. To specify multiple sFlow
collectors for flow sampling, execute this command multiple times and use different sFlow instances
each time. If you execute this command multiple times but use the same sFlow instance and different
sFlow collectors each time, the most recent configuration takes effect.
On an interface, counter sampling and flow sampling are separate from each other. They can have
the same sFlow instance but different sFlow collectors specified.
Settings of sFlow instances and sFlow collectors for different interfaces do not affect each other.
Configure this command based on actual requirement.
Examples
# Specify sFlow instance 2 and sFlow collector 2 on GigabitEthernet 1/0/1 for flow sampling.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] sflow flow instance 2 collector 2
sflow flow max-header
Use
sflow flow max-header
to set the maximum number of bytes (starting from the packet
header) that flow sampling can copy per packet.
Use
undo sflow flow max-header
to restore the default.
Syntax
sflow flow max-header length
undo sflow flow max-header
Default
Flow sampling can copy up to 128 bytes of a packet.

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.
