A-56 Dell PowerVault 720N, 740N, and 760N System Administrator and Command Reference Guide
-nShow network addresses as numbers. netstat normally interprets
addresses and attempts to display them symbolically. This option
may be used with any of the display formats that display network
addresses.
-p protocol Show statistics about protocol , which is one of tcp, udp, ip, or
icmp. A null response typically means that there are no interesting
numbers to report. The program will complain if protocol is
unknown or if there is no statistics routine for it.
-sShow per-protocol statistics. If this option is repeated, counters
with a value of zero are suppressed.
-rShow the routing tables. When -s is also present, show routing sta-
tistics instead.
-w wait Show network interface statistics at intervals of wait seconds.

The default display, for TCP sockets, shows the local and remote addresses, send
window and send queue size (in bytes), receive window and receive queue sizes
(in bytes), and the state of the connection. For UDP sockets, it shows the local
and remote addresses, and the send and receive queue size (in bytes). Address
formats are of the form host.port or network.port if a sockets address spec-
ifies a network but no specific host address. If known, the host and network
addresses are displayed symbolically according to the databases /etc/hosts and
/etc/networks, respectively. If a symbolic name for an address is not known, or
if the -n option is specified, the address is printed numerically, according to the
address family. Unspecified, or wildcard, addresses and ports appear as *.
The interface display specified by the -i or -I options provides a table of cumula-
tive statistics regarding packets transferred, errors, and collisions. The network
addresses of the interface and the maximum transmission unit (mtu) are also
displayed. If the interface is currently down, then a * is appended to the inter-
face name.
When an interval is specified, a summary of the interface information, consisting
of packets transferred, errors, and collisions, is displayed.
The routing table display indicates the available routes and their status. Each
route consists of a destination host or network and a gateway to use in forward-
ing packets. The flags field shows a collection of information about the route
stored as binary choices; the flags are:
2Protocol-specific routing flag #2 (for ARP entries, means that the entry is
published).
CUse of this route will cause a new route to be generated and used.
DThe route was created dynamically by a redirect.
GThe route is to a gateway.
