PING Test Results
6371-A2-GB20-00
The PING program is an IP-based application used to test reachability to a
specific IP address by sending an ICMP echo request and waiting for a reply.
From the Command Line Interface, PING can test connectivity upstream or
downstream.
ping dest-ip [ mgt | -x source-ip ] [-l bytes] [-w time ]
PINGs the specified destination IP address. Once PING starts, the input prompt will not
redisplay until either the PING finishes or the PING command is aborted with Ctrl-c.
Minimum access level: Administrator
dest-ip – The destination IP address of the device to PING.
source-ip – The source IP address to be used. The default source address is from the
service domain in which the test is being done. The IP address is validated to verify that
it is an interface IP address.
mgt – Specifies that the IP address is in the management domain (through the MCC).
Do not use with –x source-ip selection.
bytes – Bytes of data (l = length). Default = 64 bytes. Range = 0–15,000.
time – Number of seconds to wait before ending PING attempt. Default = 10 seconds.
Range = 0–60.
Example: ping 135.300.41.8 mgt –l 144 –w 30
PING test results display in the following formats.
