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, the device lists the first four responses to the
ping.

NOTE
This section describes the IPv4 traceroute command. For details about IPv6 traceroute, refer to
Use the traceroute command to determine the path through which a Brocade device can reach
another device. Enter the command at any level of the CLI.
The CLI displays trace route information for each hop as soon as the information is received.
Traceroute requests display all responses to a given TTL. In addition, if there are multiple
equal-cost routes to the destination, the Brocade device displays up to three responses by default.
