Using the IPv6 traceroute command
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 - 4000. The default is 16.
The no-fragment keyword turns on the “don't 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 that 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.
Using the IPv6 traceroute command
The traceroute command allows you to trace a path from the device to an IPv6 host.
The CLI displays trace route information for each hop as soon as the information is received.
Traceroute requests display all responses to a minimum TTL of 1 second and a maximum TTL of 30
seconds. In addition, if there are multiple equal-cost routes to the destination, the device displays
up to three responses.
For example, to trace the path from the device to a host with an IPv6 address of
2001:db8:349e:a384::34, enter the following command.
Brocade# traceroute ipv6 2001:db8:349e:a384::34
Syntax: traceroute ipv6 ipv6-address
The ipv6-address parameter specifies the address of a host. You must specify this address in
hexadecimal using 16-bit values between colons as documented in RFC 2373.
