Testing the Network

The superuser CLI ping command tests and measures the LAN. Also, it
can isolate a single-point hardware or software failure. The ping
command sends out an Internet Control Message Protocol (ICMP) echo
request packet each second, or until input from the terminal terminates
the command. After completing, ping displays a summary of all echo
replies received. This display includes a calculation of the time, in
milliseconds, that it takes to return the message (if the number of data
bytes is 8 or greater). Table B-11 lists the arguments for this command
The syntax is:
ping [–artv] host [databytes [count]]

Table B-11. Arguments for the ping Command

Argument Description
–a Generates AppleTalk Echo Protocol (AEP) echo request
packets to a target node.
–r Bypasses the normal routing table and sends the message
directly to a host on an attached network. An error returns if the
host is not on a directly attached network.
–t Traces the path of a packet from the local host to the destination
host and back, displaying information about each router in the
path. This option allows you to see whether a packet arrived at
and/or returned from its remote destination and, if not, where it
stopped. The option is based on the Traceroute facility
described in RFC 1393 (see Using the –t (traceroute) Option on
page A-165 for more details).
You can use –t with the –r and/or –v argument(s), but not with
–a.
