Pinging an IPv4 address

Pinging an IPv4 address
To verify that a BigIron RX device can reach another device through the network, enter a command
such as the following at any level of the CLI on the BigIron RX device:
BigIron RX> ping 192.33.4.7
Syntax: ping <ip addr> | <hostname> [source <ip addr>] [count <num>] [timeout <msec>] [ttl
<num>] [size <byte>] [quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>]
[brief [max-print-per-sec <number>] ]
NOTE
If the device is a BigIron RX Layer 2 Switch or Layer 3 Switch, you can use the host name only if you
have already enabled the Domain Name Server (DNS) resolver feature on the device from which you
are sending the ping. Refer to
“Configuring Domain Name Server (DNS) resolver” on page 174.
The required parameter is the IP address or host name of the device.
The source <ip addr> specifies an IP address to be used as the origin of the ping packets.
The count <num> parameter specifies how many ping packets the device sends. You can specify
from 1 – 4294967296. The default is 1.
The timeout <msec> parameter specifies how many milliseconds the BigIron RX device 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 <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 – 4000. 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.
