IPv6 Interface

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

“ip domain-lookup”

on page 580). If necessary, local devices can also be specified in the DNS static host table
(see

“ip host”

on page 582).

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.

Example

Console#ping6 FE80::2E0:CFF:FE00:FC%1/64

Type ESC to abort.

Console#

traceroute6

This command shows the route packets take to the specified destination.

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.

Default Setting
None

Command Mode
Privileged Exec

Command Usage

Use the traceroute6 command to determine the path taken to reach a specified destination.
