Managing System Functions

The Brocade Virtual ADX can ping using arbitrary source IP addresses (Src-IPs) belonging to the
device. The source-ip-addr was the management IP of the device by default. You have the flexibility
to use any source-ip-addr belonging to the device.
To verify connectivity to a device, enter the ping command such as the following.
Virtual ADX> ping 10.22.2.33
Syntax: ping dest-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]
The hostname variable can be used only if you have already enabled the Domain Name Server
(DNS) resolver feature on the device from which you are sending the ping. See ip dns domain-name
and ip dns server-address.
The dest-ip-addr variable specifies the IP address to be used as the destination of the ping packets.
The source-ip-addr variable specifies the IP address to be used as the source (origin) of the ping
packets.
The count num parameter specifies the number of ping packets the device sends. You can specify
from 1 – 4294967296. The default is 1.
The timeout msec parameter specifies the number of milliseconds the Brocade Virtual ADX 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 option turns on the “do not fragment” bit in the IP header of the ping packet. This
option is disabled by default.
The quiet option 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 option ensures 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 specifies 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. 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.
If you address the ping to the IP broadcast address, the device lists the first four responses to the
ping.
