Physical startup of the Catalyst switch

Physical startup of the Catalyst switch 
6.1.1
The following are points to observe before starting the switch:
  • Verify the cable and console connection.
  • Attach the power cable plug to the switch power supply socket.
  • Observe the boot sequence:
  • LEDs on the switch chassis
  • Cisco IOS software output text
The following are points to observe during the initial startup of a Catalyst switch:

  • System startup routines initiate the switch software
  • Initial startup uses default configuration parameters
Step
Action
1
 Before starting the switch, verify the following:
  • All network cable connections are secure.
  • The terminal is connected to the console point.
  • A console terminal application, such as HyperTerminal, is selected.
2
Attach the power cable plug to the switch power supply socket. The switch should power up. Note that most switches do not have on/off switches.
3
 Observe the following boot sequence:
  • LEDs on the switch chassis
  • Cisco IOS software output text
This page will explain the features, functions, and startup of switches.
Switches are dedicated, specialized computers that contain a central processing unit (CPU), random access memory (RAM), and an operating system. As shown in Figure , switches usually have several ports that hosts can connect to, as well as specialized ports for the purpose of management. Switches can be managed and the configuration can be viewed and changed through the console port.
Switches typically have no power switch to turn them on and off. They simply connect or disconnect from a power source.
Several switches from the Cisco Catalyst 2900 series are shown in Figure . There are 12-port, 24-port, and 48-port models. The top two switches in Figure are fixed configuration symmetrical switches that offer FastEthernet on all ports or a combination of 10Mbps and 100Mbps ports. The next three switches are asymmetrical models with two fixed fiber or copper Gigabit Ethernet ports. The bottom four switches are asymmetrical models with modular Gigabit Interface Converter (GBIC) slots, which can accommodate a variety of copper and fiber media options.
The next page will discuss LED indicators on a switch.

OSI layers / Peer-to-peer communications / TCP/IP model

OSI layers 2.3.4 This page discusses the seven layers of the OSI model. The OSI reference model is a framework that is used to understand how information travels throughout a network. The OSI reference model explains how packets travel through the various layers to another device on a network, even if the sender and destination have different types of network media. In the OSI reference model, there are seven numbered layers, each of which illustrates a particular network function. - Dividing the network into seven layers provides the following advantages: • It breaks network communication into smaller, more manageable parts. • It standardizes network components to allow multiple vendor development and support. • It allows different types of network hardware and software to communicate with each other. • It prevents changes in one layer from affecting other layers. • It divides network communication into smaller parts to make learning it easier to understand. In the foll...

Advantages and disadvantages of link-state routing

Advantages and disadvantages of link-state routing 2.1.5  This page lists the advantages and disadvantages of link-state routing protocols. The following are advantages of link-state routing protocols:  Link-state protocols use cost metrics to choose paths through the network. The cost metric reflects the capacity of the links on those paths. Link-state protocols use triggered updates and LSA floods to immediately report changes in the network topology to all routers in the network. This leads to fast convergence times. Each router has a complete and synchronized picture of the network. Therefore, it is very difficult for routing loops to occur. Routers use the latest information to make the best routing decisions. The link-state database sizes can be minimized with careful network design. This leads to smaller Dijkstra calculations and faster convergence. Every router, at the very least, maps the topology of it...

Ports for services

Ports for services 10.2.2  Services running on hosts must have a port number assigned to them so communication can occur. A remote host attempting to connect to a service expects that service to use specific transport layer protocols and ports. Some ports, which are defined in RFC 1700, are known as the well-known ports. These ports are reserved in both TCP and UDP.  These well-known ports define applications that run above the transport layer protocols. For example, a server that runs FTP will use ports 20 and 21 to forward TCP connections from clients to its FTP application. This allows the server to determine which service a client requests. TCP and UDP use port numbers to determine the correct service to which requests are forwarded. The next page will discuss ports in greater detail.
