Syntax
ping6 {ipv6-address | host-name} [count count] [size size]
ipv6-address - The IPv6 address of a neighbor device. You can specify either
a link-local or global unicast address formatted according to RFC 2373 “IPv6
Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal
values. One double colon may be used in the address to indicate the
appropriate number of zeros required to fill the undefined fields.
host-name - A host name string which can be resolved into an IPv6 address
through a domain name server.
count - Number of packets to send. (Range: 1-16)
size - Number of bytes in a packet. (Range: 0-1500 bytes)
The actual packet size will be eight bytes larger than the size specified
because the router adds header information.
Default Setting
count: 5
size: 32 bytes
Command Mode
