PLANET WGSW-50040 - Manual (Page 408)

Usage Guide:
If the packet sample can not be identified whether it is IPv4 or IPv6 when sent to the CPU, certain
length of the head of the group has to be copied to the sFlow packet and sent out. The length of the
copied content is configured by this command.
Example:
Configure the length of the packet data head copied in the sFlow data sampling to 50.
Switch(Config-If-Ethernet1/2)#sflow header-len 50
30.5 sflow data-len
Command:
sflow data-len <length-value>
no sflow data-len
Function:
Configure the max length of the sFlow packet data; the “no sflow data-len” command restores to
the default value.
Parameter:
<length-value> is the value of the length with a value range of 500-1470.
Command Mode:
Port Mode.
Default:
The value is 1400 by default.
Usage Guide:
When combining several samples to a sFlow group to be sent, the length of the group excluding the
MAC head and IP head parts should not exceed the configured value.
Example:
Configure the max length of the sFlow packet data to 1000.
switch (Config-If-Ethernet1/2)#sflow data-len 1000
30.6 sflow counter-interval
Command:
sflow counter-interval <interval-value>
