- Exercise 2 - Essential Switch Configuration
Step 10Enter the following login details: login as: Joe Press Enter. Password: CISCO Press Enter. Note: When typing the password, the characters will not appear on the screen. Figure 1.6 Screenshot of PLABCSCO01: Entering login details in the PuTTY terminal window. You are now successfully logged in to a router over SSH protocol. Note that you are logged in privileged exec mode because you used an account with the highest privilege level defined (privilege level 15). From this mode, you can enter configuration mode and start configuring your device. 1 Screenshot Click the button to take a screenshot of PLABCSCO01 Take screenshot To retake this screenshot click here. 1 of 7 Leave all devices in their current state and proceed to the next exercise. Exercise 2 - Essential Switch ConfigurationIn this exercise, you will configure some essential settings on a Cisco switch. A switch is a networking device that connects end devices in a network. It is a multiport network bridge that forwards data based on an Ethernet address (MAC address), which is stored in the MAC address table. MAC addresses are a 48-bit long binary number, but most devices show MAC addresses as a 12-digit hexadecimal number. For example, in Cisco switches, you will see a MAC address as 0000.0C12.3456. Most MAC addresses represent a single NIC(Network Interface Card) or Ethernet port, and it is important to remember that MAC addresses are unique. You will learn more about MAC address table in later modules. There are two general switch types, a layer 2 (L2) switch, and a layer 3 (L3) switch. An L2 switch only performs switching, which means that it uses the MAC address to switch a frame from source port to a destination port. An L3 switch also performs switching like an L2 switch, but it is also capable of performing routing and inter-vlan routing based on IP addresses. When a switch has been turned on for the first time, or when the configuration has been erased, the initial configuration dialog is displayed. Instead of using the initial configuration dialog, you will use the command line interface, or CLI, to configure the settings detailed in this module. It is uncommon that the initial configuration dialog is used in the real world. Almost all of your Cisco configurations will be done using CLI. Hence experience using CLI is vital. Note: Please refer to your course material for reference on the commands used in this exercise, or use your preferred search engine to gain an understanding of these tasks. To put into context how and what you are accessing when using this remote lab, here is some brief information on the devices you have access to. At the current time of writing, the lab has two different types of switches: Cisco 2960 24 port series - L2 switch Cisco 3750v2 series - L3 switch (or v1 depending on the lab) series. The Cisco 3750 series switch has Power over Ethernet (PoE) capabilities, which enable connections to devices that are capable of drawing their power source from the network, such as a Cisco IP phone or camera, for example. As corporate and SME networks are moving towards IP telephony, providing power over the network to these devices has become very popular. On the front of the switch are the switch interfaces where the network cables connect and a small button which changes the LED’s on the front of the switch to do various things. Below are images of the front of both the Cisco 3750 and the Cisco 2960 series switches. These are the exact physical devices you will be accessing. Download 1.21 Mb. Share with your friends:
