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 from the craft interface, use
the zone index 4097.
•
When pinging a host name, be sure the DNS server has been enabled (see
). If
necessary, local devices can also be specified in the DNS static host table (see
).
•
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
traceroute {ipv6-address | host-name}
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.
