Cisco Introduction to Layer 2 Switching. Cisco Systems. Â Â Â Â Â
There are different types of switches. You can have all three types of switches in your network. The Network Switch is a low cost end product for most home/small businesses. The Blade Switch is a thin/hypervisor-based device with higher performance. The Access Swtch is a more affordable device.
It will help to know the types and functions of switches before you configure them for any reason.
Starting with the Layer 2 Switches
Layer two (L2) switch is basic network switch for internet infrastructure that also provides network services such as internet access and addressing for local area networks (LANs). Unlike a router which provides routing services, a Layer 2 switch is only responsible for switching packets from one port to the other, based on the MAC address that is in the header of the packet.
While basic L2 switches provide just basic features, they are generally used with L3 switches as a building block. Most L2 switches support layer 2 technology such as Spanning Tree Protocol (STP), the IEEE 802. 1D standard for Data Encryption Standard (DES) cryptography, IEEE 802. 1. A few models support IEEE 802. 1e for the more secure advanced encryption standard (AES) cryptography. Some models support the so-called Rapid Spanning Tree (RSTP) protocol, developed by Cisco Systems, for IEEE 802. 1e.

A L2 switch is a network switch capable of spanning physical and data links. Most of the physical links are Ethernet links connecting two or more Ethernet networks; an L2 switch can connect Ethernet based local area networks (LANs) as well as Ethernet based wide area networks (WANs).

Download the adapter driver. If you cannot open the file, you must use the default location.
Select the 1140.
Click “Add”, then browse for the file.
Click “Install”, then restart the PC.
The interface should now be listed in the “Network and Sharing Center” Windows desktop.
Tap “Router Settings” and select “Router”.
Tap “Device Manager”.
Tap “Network Settings”.
Click “Miscellaneous Settings”.
Tap “Default IPv4 Settings”.
Choose “Use Automatic” to automatically configure the IP address.
Choose “Use DHCP” to use dynamic IP allocation.
Choose “Use automatic private addressing” to use private addressing.
The private address is the IP address configured on the LAN subinterface of the 1140.
IP address: private IP address to be used by
