COMMAND USAGE
◆ Use the ping6 command to see if another site on the network can be
reached, or to evaluate delays over the path.
◆ The same link-local address may be used by different interfaces/nodes
in different zones (RFC 4007). Therefore, when specifying a link-local
address, include zone-id information indicating the VLAN identifier after
the % delimiter. For example, FE80::7272%1 identifies VLAN 1 as the
interface from which the ping is sent.
◆ When pinging a host name, be sure the DNS server has been enabled
(see page 1402). If necessary, local devices can also be specified in the
DNS static host table (see page 1404).
◆ When using ping6 with a host name, the switch first attempts to
resolve the alias into an IPv6 address before trying to resolve it into an
IPv4 address.

SYNTAX
traceroute6 {ipv6-address | host-name}
[max-failures failure-count]
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
