Console port connections / Connecting router LAN interfaces

Console port connections
1.2.5 This page will provide more information about the console port.


The console port is a management port that is used to provide out-of-band access to a router. It is used to set up the initial configuration of a router and to monitor it. The console port is also used for disaster recovery procedures.

A rollover cable and an RJ-45 to DB-9 adapter are used to connect a PC to the console port. Cisco supplies the necessary adapter to connect to the console port.

The PC or terminal must support VT100 terminal emulation. Terminal emulation software such as HyperTerminal is usually used.

The following are steps to connect a PC to a router:

1. Configure terminal emulation software on the PC for the following:

• The appropriate COM port
• 9600 baud
• 8 data bits
• No parity
• 1 stop bit
• No flow control

2. Connect the RJ-45 connector of the rollover cable to the router console port.

3. Connect the other end of the rollover cable to the RJ-45 to DB-9 adapter.

4. Attach the female DB-9 adapter to a PC.

Connecting router LAN interfaces
1.2.6 This page will teach students how to connect LAN interfaces.


A router is usually connected to a LAN through an Ethernet or Fast Ethernet interface. The router is a host that communicates with the LAN through a hub or a switch. A straight-through cable is used to make this connection. A 10BASE-TX or 100BASE-TX router interface requires Category 5, or better, unshielded twisted-pair (UTP) cable, regardless of the router type.

In some cases the Ethernet connection of the router is connected directly to the computer or to another router. For this type of connection, a crossover cable is required.

The correct interface must be used. If the wrong interface is connected, it can damage the router or other networking devices. Many different types of connections use the same style of connector. For example Ethernet, ISDN BRI, console, AUX, integrated CSU/DSU, and Token Ring interfaces use the same eight-pin connector, which is RJ-45, RJ-48, or RJ-49. Students can use the Lab Activity and the Interactive Media Activity to practice LAN interface connections.

The next page will discuss WAN interface connections.

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...

1.2.2 RIP V2 Features

 1.2.2 RIP V2 Features This page will discuss RIP v2, which is an improved version of RIP v1. Both versions of RIP share the following features: It is a distance vector protocol that uses a hop count metric. It uses hold down timers to prevent routing loops – default is 180 seconds. It uses split horizon to prevent routing loops. It uses 16 hops as a metric for infinite distance. RIP v2 provides prefix routing, which allows it to send out subnet mask information with the route update. Therefore, RIP v2 supports the use of classless routing in which different subnets within the same network can use different subnet masks, as in VLSM. RIP v2 provides for authentication in its updates. A set of keys can be used on an interface as an authentication check. RIP v2 allows for a choice of the type of authentication to be used in RIP v2 packets. The choice can be either clear text or Message-Digest 5 (MD5) encryption. Clear text is the default. MD5 can be used t...
