6. nat sessions
Syntax:
nat sessions <i/f> [all | summary]
Description:
The
nat sessions
command displays a list of currently active NAT
sessions on the interface
<i/f >
. In this context, a session is a pair of
source IP addresses and port numbers (and corresponding new port
number) that NAT regards as one side of an active connection. For
each TCP or UDP session active, the source and destination IP
address and port number, and the local port number and the age of
the session, are printed.
The
all
option causes the
sessions
command to print out
information on every session, including sessions, which have timed
out. Normally the
sessions
command only shows active sessions
(those which have not timed out). The
summary
command does not
