connection. Nortel recommends that you choose meaningful names

name for the parameters.

•

Define the parameter "port" to identify the port number. For example,

use the value 25 specified the port used for SMTP servers.

• Define the parameter "state".

• Define the parameter "Listening" for monitoring TCP Servers.

A TCP Server is always up and running and in "state" of "listening" on

port 25 on a local system that runs the eFR monitoring process.

Note:

You can use the command window to verify the current servers.

The command "netstat –a –n" shows a screen similar to the one shown

in the following figure. In the figure, a TCP server, in the first column

with the value TCP, listening on port 25, in the second column ending

with :25, is in the "state" of "listening".

Figure 124

Verify current servers

Note: Important: NETSTAT assumes that TCP servers remain

listening.

ATTENTION

Only apply NETSTAT monitoring to TCP Servers that are multiple access socket

servers. When a TCP server is a single connection server, the TCP server is

connected while it is monitored by NETSTAT.

The following figure shows a more complete definition of a configuration

section monitoring the state of TCP Server that is expected to be always

in state "listening". The figures illustrates the example of an environment

running a local Internet Information Server with SMTP Server component

"listening" to default port 25.
