Brocade Communications Systems FastIron SX 1600, Configuration Manual, Page: 166 / 593

For example, to ping a device with the IPv6 address of 2001:DB8:847f:a385:34dd::45 from the Brocade device, enter the following
command.
device#ping ipv6 2001:DB8:847f:a385:34dd::45
Syntax: ping ipv6 ipv6-address [ outgoing-interface [ port | ve number ]] [ source ipv6-address ] [ count number ] [ timeout
milliseconds ] [ ttl number ] [ size 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.
• 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 - 4294967296 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 - 10000. 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 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.
Configuring an IPv6 Syslog server
To enable IPv6 logging, specify an IPv6 Syslog server. Enter a command such as the following.
device(config)#log host ipv6 2000:2383:e0bb::4/128
Syntax: log host ipv6 ipv6-address [ udp-port-num ]
