Parameters

-a source-ipv6: Specifies the source IPv6 address of an ICMP echo request. It must be a legal IPv6

address configured on the device. If this parameter is not provided, the source IPv6 address of an ICMP

echo request is the IPv6 address of the outbound interface of the request (The address selection rule is

defined by RFC 3484).

-c count: Specifies the number of times that an ICMPv6 echo request is sent. The value range is 1 to

4294967295, and the default is 5.

-m interval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply. The value range is 1

to 65535, and the default is 200.

• 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.

-s packet-size: Specifies length (in bytes) of an ICMPv6 echo request. The value range is 20 to 8100, and

the default is 56.

-t timeout: Specifies the timeout value (in milliseconds) of an ICMPv6 echo reply. The value range is 0 to

65535, and the default is 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

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 Layer 3—IP Services 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 MPLS L3VPN instance 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 Layer 3—IP Services

Configuration Guide.

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

Examples

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

<Sysname> ping ipv6 2001::1

PING 2001::2 : 56 data bytes, press CTRL_C to break
