-q: Displays only statistics. If this keyword is not specified, all information including the statistics is displayed. -s packet-size: Specifies length (in bytes) of an ICMPv6 echo request (not including the IPv6 packet header and the ICMPv6 packet header). The packet-size argument is in the range of 20 to 8100. The default value is 56. -t timeout: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The timeout argument is in the range of 0 to 65535. The default value is 2000. -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 the VPN to which the destination belongs, where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this option. -i interface-type interface-number: Specifies an outbound interface by its type and number. This option must be specified when the destination address is a multicast address or a link local address. If this option is not specified, the ICMP echo request sending interface is determined by searching the routing table or forwarding table according to the destination IP address. host: IPv6 address or host name (a string of 1 to 253 characters) for the destination. Usage guidelines To use the name of the destination host to perform the ipv6 ping operation, you must first configure DNS on the device. Otherwise, the ipv6 ping operation fails. To abort the ping ipv6 operation during the execution of the command, press Ctrl+C.

-vpn-instance
vpn-instance-name
: Specifies the VPN to which the destination belongs, where the
vpn-instance-name
