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.

Syntax: ping6 < ipv6-address hostname switch-number >

[repetitions < 1 - 10000 >] [timeout < 1 - 60 >] [source <ipv6-address> <vlan-id>] [data-size < 0 - 65507 >] [data-fill < 0 - 1024 >]

ping6 <link-local-address%vlan<vid> hostname switch-number> [repetitions < 1 - 10000 >] [timeout < 1 - 60 >] [source <ipv6-address> <vlan-id>][data-size < 0 - 65507 >] [data-fill < 0 - 1024 >]

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.
