Cisco 3750 Series SwitchBelow is an image showing the front of the 3750 series switch. Here you can see 24 RJ45 (commonly called copper) based network interfaces. These are capable of 10/100Mbps speeds. On the right, you can see two Small Form-factor Pluggable or SFP ports into which you can insert transceiver modules. These can provide fiber-based connectivity instead of just copper based RJ45 connections. Typically they will be used to uplink to another switch, perhaps to a distribution or core switch, but they could connect to any other compatible device. On the far right, you can see the mounting bracket, which is used to mount the switch into a 19-inch cabinet or rack. These mounts are often called ears. Figure 2.1 Physical Switch Devices: The front view of a Cisco 24 port 3750 series switch. Below is an image of the left of the switch. Here you can see the mode button, which changes the LED functions. By default, LEDs of the 24 RJ45 interfaces indicate network activity. However, they can be configured to indicate various other conditions. For example, they can be configured to indicate the active duplex mode of the interface, either full or half-duplex. Figure 2.2 Physical Switch Devices: Close-up of the LED indicators on the extreme left of the Cisco 24 port 3750 series switch. On the rear of the 3750 switch is the power connector, which is not shown in the following image, and 3 other connectors, two for stacking switches together using a stack cable, and finally the console port. Figure 2.3 Physical Switch Devices: Connectors on the rear of the Cisco 24 port 3750 series switch. The console port is very important as it is through this connection that you have initial access to the device. When you configure a physical switch in real life, you would normally have a small light blue cable that plugs into this console port and the other end into your laptop or PC. Then you would use your favorite terminal program such as Hyperterminal, Putty, or Tera Term, to name a few, to connect and make your initial configuration so that you can then complete your configuration remotely over the network. In the lab environment, that cable is replaced by the Internet, and the terminal software is replaced by your web browser and a special client so that you can see the terminal screen. Apart from this, your experience on the platform is as it would be in the real world. Download 1.21 Mb. Share with your friends:
