What is a switched LAN?
Interconnecting a set of LANs using switches is called Switched LAN
Can switches be used by administrators to segment their LAN?
Not really - they operate at the Data Link layer using the MAC address and therefore don't really segment a network. There are some managed switches that can do this or by using VLAN configurations, but ordinary switches will not really segment a LAN.

How do LAN switches work exactly?
LAN stands for Local Area Network. LAN switches work when switches are configured to limit broadcast levels. LAN switches are produced by the company Cisco.
What are VLANs used for?
VLANs provide the capability so virtually segregate traffic on a network. VLANs work by tagging traffic packets and ensuring that packets with separate VLAN IDs are only available at ports which have been configured for that VLAN ID.
How can you configure your lan with 29 machines and five 8 port lan switches?
just connect the switches in a star shape and connect your machines to the "edge"-switches.You've one "core"-switch which uses 4 of it's 8 ports to connect to the other switches. These edge switches have 7 ports free for machines.4x7=28 plus you've 4 ports free on your "core/center"-switch, makes 29(+3)
What does VLAN stand for?
A VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
How LAN network is helpful for banks?
Banks will benefit more from VLAN rather than LAN. VLAN allows to split your network in logical pieces, such as, accounting, credit department, fraud department etc. Also if configured properly people registered in certain VLAN can connect to it from different places in the building and do not have to be in the same room.
What is true about vlan?
VLAN is a custom network which is created from one or more local area networks. It enables a group of devices available in multiple networks to be combined into one logical network. The result becomes a virtual LAN that is administered like a physical LAN. The full form of VLAN is defined as Virtual Local Area Network.
What is the advantage of a switched LAN over a 10 Base 2 LAN?
LAN means Local Area Network
What is pvid?
A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. The pvid places the port into the set of ports that are connected under the designated VLAN ID. Also, if a trunk port has not been configured with any VLAN memberships, the virtual switch's Port VLAN ID (pvid) becomes the default VLAN ID for the ports connection.

Introduction In this final Packet Tracer Skills Integration Challenge activity for the Exploration: LAN Switching and Wireless course, you will apply all the skills you have learned including configuring VLANs and VTP, optimizing STP, enabling inter-VLAN routing and integrating wireless connectivity. Task 1: Configure and Verify Basic Device Configurations Step 1. Configure basic commands. Configure each switch with the following basic commands. Packet Tracer only grades the hostnames and default gateways. • Hostnames • Banner • Enable secret password • Line configurations • Service encryption • Switch default gateways Step 2. Configure the management VLAN interface on S1, S2, and S3. Create and enable interface VLAN 99 on each switch. Use the addressing table for address configuration. Step 3. Check results. Your completion percentage should be 13%. If not, click Check Results to see which required components are not yet completed. Task 2: Configure VTP CCNA Exploration LAN Switching and Wireless: Basic Wireless Concepts and Configuration PT Activity 7.6.1: Skills Integration Challenge All contents are Copyright © 1992-2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 3 of 5 Step 1. Configure the VTP mode on all three switches. Configure S1 as the server. Configure S2 and S3 as clients. Step 2. Configure the VTP domain name on all three switches. Use CCNA as the VTP domain name. Step 3. Configure the VTP domain password on all three switches. Use cisco as the VTP domain password. Step 4. Check results. Your completion percentage should be 21%. If not, click Check Results to see which required components are not yet completed. Task 3: Configure Trunking Step 1. Configure trunking on S1, S2, and S3. Configure the appropriate interfaces as trunks and assign VLAN 99 as the native VLAN. Step 2. Check results. Your completion percentage should be 44%. If not, click Check Results to see which required components are not yet completed. Task 4: Configure VLANs Step 1. Create the VLANs on S1. Create and name the following VLANs on S1 only. VTP advertises the new VLANs to S2 and S3. • VLAN 10 Faculty/Staff • VLAN 20 Students • VLAN 88 Wireless(Guest) • VLAN 99 Management&Default Step 2. Verify that VLANs have been sent to S2 and S3. Use the appropriate commands to verify that S2 and S3 now have the VLANs you created on S1. It may take a few minutes for Packet Tracer to simulate the VTP advertisements. Step 3. Check results. Your completion percentage should be 54%. If not, click Check Results to see which required components are not yet completed. Task 5: Assign VLANs to Ports Step 1. Assign VLANs to access ports on S2 and S3. Assign the PC access ports to VLANs: • VLAN 10: PC1 • VLAN 20: PC2 CCNA Exploration LAN Switching and Wireless: Basic Wireless Concepts and Configuration PT Activity 7.6.1: Skills Integration Challenge All contents are Copyright © 1992-2007 Cisco Systems, Inc.

Use the appropriate commands to verify your VLAN implementation. Step 3. Check results. Your completion percentage should be 61%. If not, click Check Results to see which required components are not yet completed. Task 6: Configure STP Step 1. Ensure that S1 is the root bridge for all spanning tree instances. Use 4096 priority. Step 2. Verify that S1 is the root bridge. Step 3. Check results. Your completion percentage should be 66%. If not, click Check Results to see which required components are not yet completed. Task 7: Configure Router-on-a-Stick Inter-VLAN Routing Step 1. Configure subinterfaces. Configure the Fa0/1 subinterfaces on R1 using the information from the addressing table. Step 2. Check results. Your completion percentage should be 79%. If not, click Check Results to see which required components are not yet completed. Task 8: Configure Wireless Connectivity Step 1. Configure IP Addressing for WRS2 and WRS3. Configure LAN settings and then static addressing on the Internet interfaces for both WRS2 and WRS3 using the addresses from the topology. Note: A bug in Packet Tracer may prevent you from assigning the static IP address first. A workaround for this issue is to configure the LAN settings first under Network Setup. Save the settings. Then configure the static IP information under Internet Connection Type and save settings again. Step 2. Configure wireless network settings. • The SSIDs for the routers are WRS2_LAN and WRS3_LAN, respectively. • The WEP for both is 12345ABCDE. Step 3. Configure the wireless routers for remote access. Configure the administration password as cisco123. Step 4. Configure PC3 and PC4 to access the network using DHCP. PC3 connects to the WRS2_LAN, and PC4 connects to the WRS3_LAN.
