The access port is set to access unconditionally and operates as a non-trunking, single VLAN interface that sends and receives non-encapsulated non-tagged frames. An access port can be assigned to only one VLAN. The trunk port sends and receives encapsulated tagged frames that identify the VLAN of origination.

A trunk is a point-to-point link between two switches or between a switch and a router. In this mode, the switch supports simultaneous tagged and untagged traffic on a port. Both values can be specified in a single command to allow both Telnet and SSH access default settings. Specify the number or name of the desired severity level at which messages should be logged.

Mark Malone. VIP Mentor.To create and configure a Cisco network, you need to know about routers and switches to develop and manage secure Cisco systems. Become acquainted with Cisco network devices and code listings; and find out how to manage static routing and view routing information.

While you may not use the OSI model every day, you should be familiar with it, specifically when working with Cisco switches and routers which operate at Layer 2 and Layer 3, respectively. Here are some of the items that operate at each level of the OSI model:. Like all networks, a Cisco network needs to be properly configured.

To do so, you need to know the configuration modes to use when configuring your network. You also should know how to configure an interface, configure a switch management interface, and configure an interface to use DHCP for your Cisco network.

When moving around in the Cisco IOS, you will see many prompts. These prompts change as you move from one configuration mode to another. Here is a summary of the major configuration modes:.

With user exec mode you can view the settings on the device but not make any changes. Global Configuration mode: Global Configuration mode is where you go to make global changes to the router such as the hostname.

Sub Prompts: There are a number of different sub prompts from Global Configuration mode you can navigate to such as the interface prompts to modify settings on a specific interface, or the line prompts to modify the different ports on the device.

When working with routers in particular, but also when dealing the management interface on switches, you will often need to configure network interfaces which will either match physical interface ports or virtual interfaces in the form of a virtual LAN VLAN interface when dealing with switches.

In the case of the router, the interface is enabled using the no shutdown command in the final step; interfaces on switches are enabled by default. For your switches, to enable an IP address on your management interface, you will use something similar to this example. If you want to configure either a router or switch to retrieve its IP configuration information from a network Dynamic Host Configuration Protocol DHCP server, then you can commands like the following example. When working with your Cisco network, you may want to separate users into different broadcast domains for security or traffic reduction.

You can do this by implementing VLANs.

If you are connecting two switches together, then you will want to allow all configured VLANs to pass between the two switches. This is accomplished by implementing a trunk port. To configure port 24 on your switch to be a trunk port, you will use the following code:. EtherChannel allows you to take up to eight network ports on your switch and treat them as a single larger link.

This can be used to connect servers with multiple network cards that are bonded or teamed to a switch, or to connect multiple switches together.
