Introduction

Industrial practice is milestone training of qualified specialists. It is a kind of educational and auxiliary process, during which theoretical knowledge is consolidated in production. Practice is the final stage in the process of preparing an engineer for independent production activities.

It was a preparation for working with hardware and software components of local area networks.

Work placement assignment

The purpose of the production practice is to study the hardware and software components local computer network and the acquisition of practical skills in their application.

Tasks to be solved during the internship:

Exploring questions scientific organization labor and production management, safety and labor protection;

Gaining experience with technological documentation;

The choice of the topic of the graduation project;

Collection and study of materials necessary for the completion of the graduation project.

1 Plan for the execution of work during the period of practice

Study of technical documentation for structured cabling systems.

Installation and certification of structured cabling systems.

Studying the technical documentation for the switch.

Switch configuration via console.

Configuring the "client" software for networking.

2 Description of work performed during the period of practice

2.1 Materials studied

Familiarized with technical documentation for structured cabling systems, received an assignment for an internship.

He got acquainted with the components used in the creation of structured cabling systems: electrical and optical cables, switching and distribution devices, cords, mounting equipment and decorative boxes.

2.2 Completion of an individual task

1) configuring the switch via the console

D-Link 3624i is a 20-port Ethernet and Fast Ethernet managed switch with the option of installing Gigabit Ethernet blocks. The data transfer rate and packet filtering rate between ports at 100% load is 14880 packs / s (when operating in 10 Mbps mode), 144810 packs / s (when operating in 100 Mbps mode) or 1448100 packs / s (when operating in 10 Mbps mode) operating in 1000 Mbps mode).

All ports automatically switch between 10/100 Mbps and full duplex/half duplex operation. In self-learning mode, the switch can contain up to 12 thousand MAC addresses in the address table, the lifetime of which varies from 10 to 9999 seconds. The switch supports broadcast storm filtering, IGMP (Internet Group Multicast Protocol), Spanning Tree algorithm and VLAN.

D-LINK 3624i Switch

locally via the serial port of the RS-232 switch (Diagnostics port);

through the network using the TCP/IP telnet protocol;

through the network using the http protocol.

The initial configuration must be done through the console connected to the Diagnostics port.

To gain access to switch management, you need to access the serial port of the workstation connected to the Diagnostics port of the switch. The registration window will appear on the screen (Figure 1.2).

Figure 1.2 - Registration on the switch

After registration, the user enters the switch management menu. Its structure (when controlled by telnet and locally) is as follows:

VLAN setting

D-Link switches use three types of VLANs and broadcast domains: IEEE 802.1Q VLAN, port-based VLAN, and MAC address-based broadcast domains. Only one of these technologies can be implemented in one device at a given time. Broadcast domains based on MAC addresses and VLANs based on ports are limited to a single switch and devices directly connected to it. IEEE 802.1Q VLANs support packet tagging, which allows VLANs to be distributed across the entire LAN (assuming all switches in the network support the IEEE 802.1Q standard).

All types of VLANs allow you to segment the network in order to reduce the size of broadcast domains. All broadcast, multicast, and unknown packets that enter the switch from a specific VLAN or broadcast domain are only forwarded to stations (MAC-based) or ports (802.1Q and port-based) that are members of that VLAN or broadcast domain. An 802.1Q VLAN can be configured to restrict the propagation of unicast packets to members of a particular VLAN, thus providing some degree of network security.

The VLAN Configuration menu displays the status of the current VLAN mode and allows you to assign one of the virtual network types. Please note that the switch can only support one mode at a time. Each time a mode is changed, the switch must be rebooted before the new mode becomes active.

VLAN Configuration Based on MAC Addresses

The switch supports up to 12 broadcast domains based on MAC addresses.

Because MAC addresses are hardwired to a station's network interface, a network administrator can physically move a station while maintaining its broadcast domain membership. This is useful on networks where stations move frequently, such as where people using laptops are constantly connected in different parts of the network.

Setting broadcast domains to MAC addresses is a relatively simple process. Simply create a broadcast domain, assign its name (description) and add MAC addresses for stations that will be members of the domain.

In the switch menu, the type of virtual network is selected (Figure 1.3), by scrolling through the values ​​using the spacebar in the Restart VLAN Mode line. The Current VLAN Mode line displays the VLAN type currently set.

After rebooting the switch, another line will appear in the menu: Configure MAC-based Broadcast Domains.

To create a broadcast domain, I created a domain in the Add/Remove MAC-based Broadcast Domains menu (System Configuration ® Configure VLANs & MAC-based Broadcast Domains ® Configure MAC-based Broadcast Domains) and entered MAC addresses in the Add/Remove MACbased Broadcast Domain Members menu . The switch was then rebooted.

Figure 1.3 - VLAN Configuration Menu Screen

2) configuring the "client" software for networking.

Configuring the client side of VPN under Windows 2000 Server.

In order to start setting up, we need to log in to the system with account Administrator.

On the desktop, we will find the My Network Places icon.

Right-click on it, select Properties from the context menu, and the Network and Dial-up Networking window will open.

We need to double-click the left mouse button on the Create a new connection icon. A wizard window will appear in this window and click the Next button.

In the window that appears, select the item Connect to a virtual private network via the Internet and click the Next button.

In the next window, in the text field, enter the IP address of the VPN series, for example, 157.54.0.1, and click the Next button as shown below:

In the next window, you need to specify that this connection will be available to all users or available only to me, now we will determine whether we want to make the created VPN connection only for ourselves, or for all users who can work with the computer.

For security reasons, it makes sense to create a separate connection for each user, and not use a common one, so we create this connection for only one user and click the Next button.

Now in the next window, enter (or leave it unchanged) in the corresponding field the name of the connection under which it will be stored in the Network and Remote Access folder, we will call it VPN.

We have created a VPN connection and now we will configure it.

Double-click on the icon of our VPN connection with the left mouse button and in the window that appears, click on the properties button.

The properties window for this connection will appear, go to the Security tab, and check the Advanced options box, then click the Settings button.

In the window that appears, Additional security settings, check the box on the Password verification protocol (CHAP) tab.

Let's go to the Network tab. In the Components checked are used by this connection list, uncheck all boxes except Internet Protocol (TCP/IP) and click OK.

Now you can connect to VPN networks but before that you need to connect to the Internet.

Practice Conclusion

During the internship:

1) gained practical experience in working with technical documentation;

2) got acquainted with the switch settings through the console

3) got acquainted with the principles of SCS design

4) the theme of the graduation project is chosen.
