Note that the agent-to-collector datagrams contain their own UDP headers, which are
outside this calculation.
Example To set the maximum header size to 160 bytes for ports 1.0.1 and 1.0.7, use the commands:
Related Commands show running-config sflow
show sflow interface
sflow max-header-size
Caution In the above network scenarios:
■ For IPv4 - any data existing between 66 bytes and the value set by this
command will be included in the sFlow packet samples. For example,
with the default of 128 applied, up to 128-66=62 bytes of user data
could be included in the sFlow datagram samples sent between the
Agent and the Collector.
■ For IPv6 - any data existing between 82 bytes and the value set by this
command will be included in the sFlow packet samples. For example,
with the default of 128 applied, up to 128-82=46 bytes of user data
could be included in the sFlow datagram samples sent between the
Agent and the Collector.
