IPv6 management features
<bytes>] [quiet] [numeric] [no-fragment] [verify]
[data <1-to-4 byte hex>] [brief]
• The <ipv6-address> parameter specifies the address of the router. You must specify this
address in hexadecimal using 16-bit values between colons as documented in RFC 2373.
• The outgoing-interface keyword specifies a physical interface over which you can verify
connectivity. If you specify a physical interface, such as an Ethernet interface, you must also
specify the port number of the interface. If you specify a virtual interface, such as a VE, you
must specify the number associated with the VE.
• The source <ipv6-address> parameter specifies an IPv6 address to be used as the origin of
the ping packets.
NOTE
The outgoing-interface and source options are available only on Layer 3 code and not on Layer
2 code.
• The count <number> parameter specifies how many ping packets the router sends. You can
specify from 1 - 4294967296. The default is 1.
• The timeout <milliseconds> parameter specifies how many milliseconds the router waits for a
reply from the pinged device. You can specify a timeout from 1 - 4294967294 milliseconds.
The default is 5000 (5 seconds).
• The ttl <number> parameter specifies the maximum number of hops. You can specify a TTL
from 1 - 255. The default is 64.
• The size <bytes> parameter specifies the size of the ICMP data portion of the packet. This is
the payload and does not include the header. You can specify from 0 - 10173. The default is
16.
• The no-fragment keyword turns on the "do not fragment" bit in the IPv6 header of the ping
packet. This option is disabled by default.
• The quiet keyword hides informational messages such as a summary of the ping parameters
sent to the device, and instead only displays messages indicating the success or failure of the
ping. This option is disabled by default.
• The verify keyword verifies that the data in the echo packet (the reply packet) is the same as
the data in the echo request (the ping). By default the device does not verify the data.
• The data <1 - 4 byte hex> parameter lets you specify a specific data pattern for the payload
instead of the default data pattern, "abcd", in the packet's data payload. The pattern repeats
itself throughout the ICMP message (payload) portion of the packet.
NOTE
For parameters that require a numeric value, the CLI does not check whether the value you
enter is within the allowed range. Instead, if you do exceed the range for a numeric value, the
software rounds the value to the nearest valid value.
• The brief keyword causes ping test characters to be displayed. The following ping test
characters are supported.
! Indicates that a reply was received.
. Indicates that the network server timed out while waiting for a reply.
U Indicates that a destination unreachable error PDU was received.
I Indicates that the user interrupted ping.
