Parameter -asource-ipv6: Specifies the source IPv6 address of an ICMP echo request. It must be a legal IPv6 address configured on the device.

-ccount: Specifies the number of times that an ICMPv6 echo request is sent, in the range 1 to 4294967295. The default value is 5.

-minterval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply, in the range 1 to 65535. The default value is 200 ms.

■If a response from the destination is received within the timeout time, the interval to send the next echo request equals the actual response period plus the value of interval.

■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.

-spacket-size: Specifies length (in bytes) of an ICMPv6 echo request, in the range 20 to 8100. It defaults to 56.

-ttimeout: Specifies the timeout value (in milliseconds) of an ICMPv6 echo request, in the range 0 to 65535. It defaults to 2000.

remote-system: IPv6 address or host name (a string of 1 to 46 characters) of the destination device.

-iinterface-typeinterface-number: Specifies an outgoing interface by its type and number. This parameter can be used only in case that the destination address is the link local address and the specified outgoing interface must have a link local address (For the configuration of link local address, see “IPv6 Basics Configuration Commands” on page 829).

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

You must use the command in the form of ping ipv6 ipv6 instead of ping ipv6 if the destination name is an ipv6 name.

Example # Verify whether the IPv6 address 2001::1 is reachable.

<Sysname> ping ipv6 2001::1
PING 2001::1 : 56 data bytes, press CTRL_C to break
