sflow max-header-size extended
By default, the maximum header size of a packet is 128 bytes. When sflow max-header-size
extended is enabled, 256 bytes are copied. These bytes are useful for VxLAN, NvGRE, IPv4, and IPv6
tunneled packets.
NOTE: Interface mode configuration takes priority.
• To reset the maximum header size of a packet, use the following command
[no] sflow max-header-size extended
• View the maximum header size of a packet.
