Network connectivity testing
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, 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.
Tracing an IPv4 route
NOTE
This section describes the IPv4 traceroute command. For details about IPv6 traceroute, refer to
“IPv6 traceroute” on page 368.
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.
