R3721-F3210-F3171-HP High-End Firewalls System Management and Maintenance Command Reference-6PW101

-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 46 characters.

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

can be used only in case that 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 option 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 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.

Description

Use ping ipv6 to verify whether an IPv6 address is reachable, and display the corresponding statistics.

To use the name of the destination host to perform the ping operation, you must configure DNS on the

device first; otherwise, the ping operation fails. For more information about DNS, see Network

Management Configuration Guide. You must use the command in the form of ping ipv6 ipv6 instead of

ping ipv6 if the destination name is an ipv6 name.

To abort the ping ipv6 operation during the execution of the command, press Ctrl+C.
