The -b option must be specified to enlarge the size of the socket buffer and the -s option specifies the length of the packet, which should be more than 65,535. For example, type as follows: [source,bash] .... -% ping6 -b 70000 -s 68000 ::1 +% ping -6 -b 70000 -s 68000 ::1 .... The IPv6 specification requires that the Jumbo Payload option must not be used in a packet that carries a fragment header. |
