ping ipv6
Copyright © 2010, Juniper Networks, Inc.
Use to enable or disable an IPv6 interface at any time.
NOTE: By default, an IPv6 interface is enabled when you first create it.
Example
host1(config-if)#ipv6 enable
Use the no version of this command to disable IPv6 on an interface or a subinterface.
See ipv6 enable
Use to send an ICMP echo request packet to the IPv6 address that you specify.
Use the source interface keywords to specify a source interface other than the one
from which the probe originates.
Use the source address keywords to specify a source IP address other than the one
from which the probe originates.
You can specify the following options:
packetCount—Number of packets to send to the destination IPv6 address. If you
specify a zero (0), echo requests packets are sent indefinitely.
data-pattern—Sets the type of bits contained in the packet to all ones, all zeros, a
random mixture of ones and zeros, or a specific hexadecimal data pattern that can
range from 0x0–0xFFFFFFFF. The default is all zeros.
data-size—Sets the number of bytes comprising the IPv6 packet and reflected in
the IPv6 header in the range 0–64000; the default is 100 bytes
extended header attributes—Set the interface type and specifier of a destination
address on the router that is connected for external loopback by means of a cable
or plug that loops Tx to Rx. The command succeeds only if the specified interface
is connected for external loopback and the encapsulation type is ATM, Frame Relay,
HDLC, or PPP. The command does not work for Ethernet or VLAN encapsulations.
sweep-interval—Specifies the change in the size of subsequent ping packets while
sweeping across a range of sizes. For example, you can configure the sweep interval
to sweep across the range of packets from 100 bytes to 1000 bytes in increments
equal to the sweep interval. By default the router increments packets by one byte;
for example, it sends 100, 101, 102, 103, ... 1000. If the sweep interval is 5, the router
sends 100, 105, 110, 115, ... 1000.
sweep-sizes—Enables you to vary the sizes of the echo packets being sent. This
capability is useful for determining the minimum sizes of the MTUs configured on
the nodes along the path to the destination address. This reduces packet
fragmentation, which contributes to performance problems. The default is not to
sweep (all packets are the same size).
