The IPv6 syntax for this command is ping ipv6 host or ping ipv6 ipv6-address. The following example
pings an IPv6 link-local address configured on a specific address:
shellfish# ping ipv6 fe80::205:30ff:fe01:a4fa interface gigabitethernet 1/1
PING fe80::205:30ff:fe01:a4fa(fe80::205:30ff:fe01:a4fa) from ::1 gige1-1: 56 data bytes
64 bytes from fe80::205:30ff:fe01:a4fa: icmp_seq=1 ttl=64 time=0.091 ms
64 bytes from fe80::205:30ff:fe01:a4fa: icmp_seq=2 ttl=64 time=0.077 ms
64 bytes from fe80::205:30ff:fe01:a4fa: icmp_seq=3 ttl=64 time=0.080 ms
64 bytes from fe80::205:30ff:fe01:a4fa: icmp_seq=4 ttl=64 time=0.075 ms
64 bytes from fe80::205:30ff:fe01:a4fa: icmp_seq=5 ttl=64 time=0.076 ms
To abnormally terminate a ping session, type the Ctrl-C escape sequence.

Options and Defaults for the ping and ping ipv6 Commands
Description
The IPv4 address, IPv6 address, or host name of the
destination node to ping.
The number of ping packets to be sent to the destination
address.
The size of each ping packet in bytes.
The timeout interval before the ping or ping ipv6
command is terminated.
Specifies if a series of additional commands appear.
The sizes of the echo packets being sent. This option
determines the minimum sizes of the MTUs configured on
the nodes along the path to the destination address. You can
then reduce packet fragmentation performance problems
(see the
page
"Configuring the MTU Frame Size" section on
46-3).
