-s packet-size: Specifies the length (in bytes) of ICMPv6 echo requests (excluding the IPv6 packet
header and the ICMPv6 packet header). The value range is 20 to 8100, and the default is 56.
-t timeout: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The value range is 0
to 65535, and the default is 2000.
-tc traffic-class: Specifies the traffic class value in an ICMPv6 packet. The value range is 0 to 255
and the default is 0.
-v: Displays detailed information (including the dst field and the idx field) about ICMPv6 echo replies.
If this keyword is not specified, the system only displays brief information (not including the dst field
and the idx field) about ICMPv6 echo replies.
-vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the destination
belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive
string of 1 to 31 characters. If the destination is on the public network, do not specify this option.
host: Specifies the IPv6 address or host name of the destination. The host name is a
case-insensitive string of 1 to 253 characters. It can contain letters, digits, and special characters
such as hyphen (-), underscore (_), and dot (.).
Usage guidelines
To ping a device identified by its host name, configure the DNS settings on the device first. If the DNS
settings are not configured, the ping ipv6 operation fails.
To abort the ping ipv6 operation during the execution of the command, press Ctrl+C.
