• If no response from the destination is received within the timeout time, the interval to send the next

echo request equals the timeout value plus the value of interval.

-s packet-size: Specifies length (in bytes) of an ICMPv6 echo request, which ranges from 20 to 8100 and

defaults to 56.

-t timeout: Specifies the timeout value (in milliseconds) of an ICMPv6 echo reply, which ranges from 0 to

65535 and defaults to 2000.

host: IPv6 address or host name of the destination, which is a string of 1 to 255 characters.

-i interface-type interface-number: Specifies an outbound interface by its type and number. This

parameter can be used only when the destination address is the link local address and the specified

outbound interface must have a link local address (For more information about the configuration of link

local address, see Network Management Configuration Guide. If this parameter is not provided, the

ICMP echo request sending interface is determined by searching the routing table or forwarding table

according to the destination IP address.

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

vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the destination is on the public

network, do not specify this option.

Usage guidelines

To use the name of the destination host to perform the ping IPv6 operation, configure DNS on the device

first. Otherwise, the ping IPv6 operation fails. For more information about DNS, see Network

Management Configuration Guide.

To abort the ping IPv6 operation during the execution of the command, press Ctrl+C.
