Command ReferenceA-57
HThe route is to a host (otherwise, it๎‚’s to a net).
LThe route includes valid protocol to link address translation.
MThe route was modified dynamically by a redirect.
RThe route has timed out.
SThe route was manually added with a route command (see route).
UThe route is usable (๎‚”up๎‚”).
Direct routes are created for each interface attached to the local host; the gate-
way field for such entries shows the address of the outgoing interface. The refcnt
field gives the current number of active uses of the route. Connection oriented
protocols normally hold on to a single route for the duration of a connection while
connectionless protocols obtain a route whenever they transmit to a destination.
The use field provides a count of the number of packets sent using that route.
The interface entry indicates the network interface utilized for the route.
When netstat is invoked with the -w option and an interval argument, it displays
a running count of statistics related to network interfaces. An obsolescent ver-
sion of this option used a numeric parameter with no option, and is currently
supported for backward compatibility. This display consists of a column for the
primary interface and a column summarizing information for all interfaces. The
default primary interface is the first interface configured into the system. The pri-
mary interface may be replaced with another interface with the -I option. The first
line of each screen of information contains a summary since the system was last
rebooted. Subsequent lines of output show values accumulated over the preced-
ing interval.
