Ping for IPv6 (Ping6)
Ping for IPv6 (Ping6)
The Ping6 test is a point-to-point test that accepts an IPv6 address or IPv6 host
name to see if an IPv6 switch is communicating properly with another device
on the same or another IP network. A ping test checks the path between the
switch and another device by sending IP packets (ICMP Echo Requests).
To use a ping6 command with an IPv6 host name or fully qualified domain
names, refer to “DNS Resolver for IPv6” on page 8-9.
You can issue single or multiple ping tests with varying repetitions and timeout
periods to wait for a ping reply.
Replies to each ping test are displayed on the console screen. To stop a ping
test before it finishes, press
[Ctrl] [C].
For more information about using a ping test, refer to the “Troubleshooting”
appendix in the current Management and Configuration Guide for your
switch.

Pings the specified IPv6 host by sending ICMP version 6
(ICMPv6) echo request packets to the specified host.
<ipv6-address>: IPv6 address of a destination host device.
< link-local-address >%vlan<vlan-id>: IPv6 link-local
address, where %vlan<vlan-id> specifies the VLAN ID
number.
< hostname >: Host name of an IPv6 host device configured
on an IPv6 DNS server.
< switch-number >: Number of an IPv6-based switch that is
a member of a switch stack (IPv6 subnet). Valid values: 1 -
16.
[repetitions]: Number of times that IPv6 ping packets are sent
to the destination IPv6 host. Valid values: 1 - 10000. Default:
1.
