-t
timeout
: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The value range is 0
to 65535, and the default is 2000.
-tc
traffic-class
: Specifies the traffic class value in an ICMPv6 packet. The value range is 0 to 255
and the default is 0.
-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 MPLS L3VPN instance 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.
host
: Specifies the IPv6 address or host name of the destination. The host name is a
case-insensitive string of 1 to 253 characters. It can contain letters, digits, and special characters
such as hyphen (-), underscore (_), and dot (.).
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
.
