[Sysname] interface gigabitethernet 4/0/1
[Sysname-GigabitEthernet4/0/1] sflow flow collector 2

sflow flow max-header

Use sflow flow max-header to set the maximum number of bytes of a packet (starting from the packet
header) that flow sampling can copy.
Use undo sflow flow max-header to restore the default.
Syntax

Parameters
determine: Specifies the fixed sampling mode. For example, if the flow sampling rate is set to 4000 (by
using the sflow sampling-rate command), the device randomly samples a packet, like the tenth packet,
from the first 4000 packets. The next time the device samples the 4010th packet, and so on.
