Monitoring 385

Monitoring the state of the TCP server

If the SMTP Server is stopped by an administrator, the socket no longer is

"listening" on port 25 and the message "Mail Server is down" is sent as an

SNMPv1 trap to the configured SNMP destination.

Definition of a TCP client

A sample definition of a connection is shown in the following figure. The

definition is very similar to the definition of a TCP Server, but the state is

"established" instead of "listening".

Figure 126

Definition of a TCP client

The definition of a connection contains the following parameters.

• Define the parameter id which defines the unique identifier of the

monitored item. The value Messenger@Net - eCAP in the example

defines the connection. You can specify a value of your choice. Nortel

recommends that you use a name meaningful to you.

• Define the parameter "port" which defines the port number. For

example, the value 3102 specifies a specific port used by DECT

Messenger.

• Define the parameter "state". For monitoring TCP Clients, define the

value "established".

It is expected that a TCP Server is always up and running and is in

state "connected" on port 3102 with a TCP Client in the local system

that runs the eFR monitoring process.

Note: The specified port is the port on the TCP Server.
