All Aruba OS

 

 

#show netstat
============
 
This CLI command prints the network connections on the Aruba Controller. By  default, “show netstat”  displays  a  list of open sockets. Description of each column in the output:
 
Active Internet connections:
                (TCP, UDP, raw)
 
Proto:
======
The protocol (tcp, udp, raw) used by the socket.
 
Recv-Q:
=======
The count of bytes not copied by the user program connected to this socket.
 
Send-Q:
=======
The count of bytes not acknowledged by the remote host.
 
Local Address:
==============
Address  and  port  number of the local end of the socket.  Unless the --numeric (-n) option is specified, the socket address is resolved to its canonical host name (FQDN), and the port number is translated into the  corresponding service name.
 
Foreign Address:
================
Address and port number of the remote end of the socket.  Analogous to "Local Address."
 
State:
======
The state of the socket. Since there are no states in raw mode and usually no states used in UDP, this column may be left blank. Normally this can be one of several values:
 
ESTABLISHED
===========
The socket has an established connection.
 
SYN_SENT
=========
 The socket is actively attempting to establish a connection.
 
SYN_RECV
=========
 A connection request has been received from the network.
 
FIN_WAIT1
=========
The socket is closed, and the connection is shutting down.
 
 FIN_WAIT2
===========
 Connection is closed, and the socket is waiting for a shutdown from the remote end.
 
TIME_WAIT
=========
The socket is waiting after close to handle packets still in the network.
 
CLOSED
=======
The socket is not being used.
 
 CLOSE_WAIT
===========
 The remote end has shut down, waiting for the socket to close.
 
 LAST_ACK
=========
 The remote end has shut down, and the socket is closed. Waiting for acknowledgement.
 
LISTEN
======
The socket is listening for incoming connections. 
 
 
Sample output
==============
Active Internet connections (servers and established)
