TABLE 2-17 Options for ping
Option Description How It Can Help
hostname The probe packet is sent to hostname and returned. Verifies that a host is active on the
network.
-g hostname Forces the probe packet to route through a specified
gateway. By identifying different routes to
the target host, those individual
routes can be tested for quality.
-i interface Designates which interface to send and receive the probe
packet through. Enables a simple check of
secondary network interfaces.
-n Replaces host names with IP addresses. Used when an address is more
beneficial than a host name.
-s Pings continuously in one-second intervals. Ctrl-C aborts.
Upon abort, statistics are displayed. Helps identify intermittent or
long-duration network events. By
piping ping output to a file,
activity overnight can later be
viewed at once.
-svR Displays the route the probe packet followed in one second
intervals. Indicates probe packet route and
number of hops. Comparing
multiple routes can identify
bottlenecks.
