MAX-HEADER-SIZE
• A similar consideration can be made for an environment using TCP IPv6 over
Ethernet:
Ethernet header (including the 4 byte 802.1Q header component) = 18 bytes
IPv6 header = 40 bytes
TCP header = 24 bytes
Total = 82 bytes
CAUTION: 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.
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:
awplus# configure terminal
awplus(config)# interface port1.0.1,port1.0.7
awplus(config-if)# sflow max-header-size 160
