Brocade FastIron Ethernet Switch Administration Guide - Manual (Page 111)

The ttl num parameter specifies the maximum number of hops. You can specify a TTL from 1 - 255. The
default is 64.
The size byte 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 parameter turns on the "don’t fragment" bit in the IP header of the ping packet. This
option is disabled by default.
The quiet parameter 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 parameter 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 data payload. The pattern repeats itself throughout the ICMP
message (payload) portion of the packet.
NOTE
For numeric parameter values, 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 parameter 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.
NOTE
The number of ! characters displayed may not correspond to the number of successful replies by the
ping command. Similarly, the number of . characters displayed may not correspond to the number of
server timeouts that occurred while waiting for a reply. The "success" or "timeout" results are shown in
the display as "Success rate is XX percent (X/Y)".
The optional max-print-per-sec number parameter specifies the maximum number of target responses
the Brocade device can display per second while in brief mode. You can specify from 0 - 2047. The
default is 511.
NOTE
If you address the ping to the IP broadcast address and network address, the device lists the first four
responses to the ping.
NOTE
On 48GC modules in non-jumbo mode, the maximum size of ping packets is 1486 bytes and the
maximum frame size of tagged traffic is no larger than 1581 bytes.
