The Routing Table command allows checking the setting of the static routing table and the default gateway address currently used by the selected equipment (“Running” routing table and default gateway).

The function of the “routing table” is the one to check the routing of the supervisory messages exchanged among the elements (PCs, equipment, etc.), that use the TCP/IP protocol, from one network to the other one.

Warning. The “Running” routing table is a static one. The system updates such a table, through the elements present into the “Stored” routing table, at every equipment start-up.

The system forwards to the equipment with the default “gateway” function the data that have a receiver unreachable through the routes present into the routing table.

Warning. When all the equipment belong to the same IP network, it is not necessary to define the routing table and the address of the gateway equipment because the network is able to manage its own inner traffic. The setting of these parameters is necessary when the equipment belong to different networks, then, the traffic has to be routed again from a network to the other one.

The choice of this command opens the window shown in Figure 27.

If the equipment status and the user profile allow it, by means of the push-buttons present into the Routing Table window, it is possible:

to add an element to the routing table

•

Each Siae equipment at its initialisation (start-up operation) automatically sets the elements of the routing table that identify the supervisory ports ¹¹² of the equipment. These elements are set according to the IP addresses assigned to each port ¹¹³.

If it is necessary, the SCT/LMT user can add to these elements (automatically set) some other ones.

The system records each new element (manually set) into the currently used routing table (“Running” routing table) and into the backup memory of the equipment controller (“Stored”

routing table); the system does not record the elements (automatically set) into the backup memory of the controller because they are newly set at every equipment start-up.

to remove an element from the routing table

•

Warning. The removal of an element (automatically set) causes and automatic new insertion of the element itself at the next equipment start-up.

• to reset the “Stored” routing table

• to set or modify the IP address used as default gateway

• to delete the IP address used as default gateway

112 Communication ports provided with the equipment for the input/output of the supervisory signal.

113 Warning. If the user changes the IP address of a supervisory port, the system does not dynamically change it into the equipment routing table. It is necessary to execute a reset of the equipment, because the elements of the routing table are set at the equipment start-up.

Figure 27 Notes of

(1) If the operator has not set any identification code, the program points out the IP address (SNMP agent) of the equipment.

(2) The system points out also the MIB version (Management Information Base), when the relevant value is available into the MIB loaded on the equipment under examination.

(3) The wording:

− Lan, identifies the communication port with the LAN network.

− Lan/OSI, identifies the inner communication port that interfaces itself with the router OSI.

− Lct, identifies the port for the connection with the PC over which it is present the SCT/LMT application program.

− RS232, identifies the serial port for the connection with other network elements.

− Radio, identifies the communication port (radio side) represented by the radio signal (communication port present into the radio equipment: PDH, SDH).

146 SCT/LMT Release 1.4 – MN.00095.E – 013

− 2Mb/s, identifies the E1 communication port (2Mb/s) (communication port present into the PMP equipment).

− Agg. West, identifies the communication port represented by the West side aggregate signal (communication port present into the ADM-C equipment).

− Agg. East, identifies the communication port represented by the East side aggregate signal (communication port present into the ADM-C equipment).

− RS232/2Mb, identifies the communication port RS232 or 2Mbps (at user’s choice) for the connection with other network elements (communication port present into the PDH-AL equipment).

(4) The wording:

− LOCAL, points out that the element has been automatically inserted by the controller. The element identifies the network and/or the interface directly connected with the equipment.

− NETMGMT, points out that the element has been manually inserted by the user (static element).

OSPF, points out that the element has been automatically inserted by the OSPF protocol (dynamic element).

−

− OTHER, point out all the other situations that are not comprised into one of the previous cases ¹¹⁴.

To add an element to the routing table

1. Into the Station List area (SCT/LMT window), select the station that contains the desired equipment.

2. Select, into the Equipment list area (SCT/LMT window), the equipment.

3. Select the Equipment – Communication Setup – Routing Table command.

The system displays the Routing Table window.

4. Choose the Add push-button.

The system displays the Routing Table Params window.

5. Into the Destination box, type the IP Address of the destination element (equipment, network, etc.).

For each one of the four available spaces (sub-divided by a dot), insert a number comprised between 0 and 255.

6. Into the NetMask box, type the mask for the network address definition of the destination element (equipment, network, etc.).

For each one of the four available spaces (sub-divided by a dot), insert a number comprised between 0 and 255.

7. Into the Hop box, type the IP Address of the next router equipment.

For each one of the four available spaces (sub-divided by a dot), insert a number comprised between 0 and 255.

8. Into the Interface box, set the supervisory port that corresponds to the IP address of the router equipment.

Select the arrow placed on the side of the box and choose the desired value from the list. The available values change according to the selected equipment type. Select the wording Not selected, when the system has automatically to insert the parameter according to the IP address of the router.

9. Choose the Ok push-button.

The new element is inserted into the table.

Warning. The system records the new element into the currently used routing table (“Running”

routing table) and into the backup memory of the equipment (“Stored” routing table).
