VLAN Configuration Fundamentals and Commands

This the third part of this article. Later we configured VTP protocol in our practice lab. This the fourth part of this article. Later in this part we configured trunking in our practice lab. Office2 and Office3 switches are configured as VTP clients. VLAN can be assigned statically or dynamically. Following commands will assign VLANs to the interfaces. We have successfully assigned VLAN membership.

It's time to test our configuration. To test this configuration, we will use ping command. As per our configuration, devices from same VLAN can communicate. Devices from different VLANs must not be able to communicate with each other without router.

Let's test VLAN 10 first. These PCs must be able to communicate with each other's. Typically routers are configured to receive data on one physical interface and forward that data from another physical interface based on its configuration. Each VLAN has a layer 3 address that should be configured as default gateway address on all its devices. In our scenario we reserved IP address With default configuration we need two physical interfaces on router to make this intra VLAN communication.

Usually a router has one or two Ethernet interface. To deal with situation we use Router on Stick.The Interface Range Specification feature allows specification of a range of interfaces to which subsequent commands are applied and supports definition of macros that contain an interface range.

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release.

To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the "Feature Information for Interface Range Specification" section.

Interface Range Specification

An account on Cisco. Each command you enter while you are in interface configuration mode with the range keyword is executed as it is entered. The commands are not batched together for execution after you exit interface mode. If you exit interface configuration mode while the commands are being executed, some commands may not be executed on some interfaces in the range.

Wait until the command prompt reappears before exiting interface configuration mode. The interface range command works only with VLAN interfaces that have been created with the interface vlan command the show running-configuration command displays the VLAN interfaces. VLAN interfaces not displayed by the show running-configuration command cannot be used with the interface range command. The Interface Range Specification feature is implemented with the range keyword, which is used with the interface command.

In the interface configuration mode with the range keyword, all entered commands are applied to all interfaces within the range until you exit the interface configuration mode. For example, the command interface range gigabitethernet 1 - 5 is valid; the command interface range gigabitethernet is not valid. You can verify the configuration of a range of Interfaces by using the show running-configuration command.

Interface commands: define interface-rangeinterface rangeand interface vlan. Configuration commands: show running-configuration.

Access to most tools on the Cisco Support and Documentation website requires a Cisco.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. To set EtherChannel to use with of the protocols you will configure it to support one of the following modes. This mode can only connect to another device that is also set to on. The following example will configure EtherChannel to use group ports 11 and 12 on the switch together using PAgP as the protocol. The same type of command would be used on the switch to which Switch1 is connected.

Spanning Tree Protocol STP enables you to create redundant loops on your Cisco network for fault tolerance, and prevents inadvertent loops that may be created on your network from bringing the network to its knees.

In addition to configuring STP on the switch, you will also configure port 2 on the switch for portfast, which allows the port to immediately transition to forwarding mode. The first step in having your router pass data from one interface to another interface is to enable routing; just use these commands. Whether or not you choose to use a dynamic routing protocol, you may add static routes to your router. The following will add a static route to Router1 to send data to the The following code will enable routing, enable RIP, set RIP to version 2, disable route summarization, defines the distributed network from this router as The following is an example of the output of this command.

The output includes a legend showing the codes for each routing protocol, and the specific routes are identified by the source protocol. Security is always a concern, and your Cisco network needs to be properly secured. The following commands are used to configure NAT overload services on a router called Router1. In this example, a list of source address is created in access list 1, which is then used as the inside source list.But can that be a list vs a range?

They aren't all in order - maybe its time I organize them I guess! Look at this. If the switch is running IOS, then the only other option is to type your individual port configuration commands into a text file. Then what i do is go back and change the one or two that are different if there is a good size block of all the same vlan. Technically, I don't think you need a space before the comma, but you do need the spaces with the hyphens and after the comma. Evidently that depends on version.

Read these nextFor example, a VLAN for All three of these can be configured in the same physical switch. While these commands were tested on a cisco catalyst switch series, similar commands may be with slight variation to the port number format should work on all cisco switches. If you are planning to have only one network in your whole switch for example, Every switch comes with the default VLAN 1 as shown below.

In this example, all the ports in this switch from 1 through 8 are part of the default VLAN 1. In the following example, we are creating VLAN network for Apart from providing the access to the vlan for the port numbers 3 through 6, you can also specify the following additional switchport configuration parameters for example, nonegotiate and mode access.

On a side note, it is always recommended that you upgrade ISO image on your cisco switch to the latest version. Do this only on a test system, where you can play around and learn how to manipulate VLANs on cisco switch.

I think that is still in place even after using the no vlan command. You also need to delete the vlan. Hi please can you help how do the switch will know that port 3 to 6 are assigned to vlan with the ip adress Hi guy. To create a vlan just select a number for the vlan, like I have a catalyst g switch and I am new to cisco.

How do I set this to Mbps? Thanks in advance! Hi, I have a task to to in network switch, to replace data vlan 10 to vlan I am bit helpless to to so, request for help and options to configure things. I have locations which had a data vlan in production VLAN need to replace with same ip segment and flawless. Kindly advice.

The second section discusses a scenario in which VLANs are used, detailing the configuration commands used to meet the scenario requirements. Before we get into the commands themselves, let's examine how VLANs have been implemented on Cisco switches historically. The IEEE One change related to this conversation is that the standard provided a trunking mechanism that supported up to 4, VLANs minus the reserved ones. This welcome improvement provided additional flexibility to network engineers.

This delay gave engineers a considerable amount of time to find—and learn to prefer—VLAN assignment using the extended range without using VTP. How does this history affect how you configure VLANs? Not all Cisco Catalyst switches support the configuration of all 4, VLANs 4, minus the four reserved ; this is a limitation in the hardware of the switch.

Keep this fact in mind when purchasing a lower-end switch, to ensure that the switch will support the number of VLANs required for your specific implementation.

If an interface is configured into the VLAN being deleted, it will become inactive and will not be displayed in the output of the show vlan command. Because VTP is configured into server mode by default on most switches as of this writingthe creation of extended VLANs will fail using either of the methods shown in Tables 1 and 2. Keep in mind that this failure will not occur until you leave VLAN configuration mode, so the command itself will be accepted.

To fix this problem, either the VTP version must be changed to 3, or the VTP mode must be changed to transparent or off. VTP version differences are a bit outside the scope of this article. Table 5 shows only the command to alter the VTP mode. Suppose you work for a school at a university, and the school is in the process of moving to a different building. In the new building, administrative operations and academic labs will be located on the same floor.

Configure Cisco Management VLAN - Assigning IP Address to VLAN LAN

In the interest of saving money and time, it has been decided that all of the school's devices will be connected via a single network switch. Since security of the administrative devices is important, the administrative network must be physically or virtually separated from the academic network. To set up this design, each interface must be configured into its respective VLAN.VLAN information is not saved in the running-config or startup-config but in a separate file called vlan.

If you want to delete the VLAN information you should delete this file by typing delete flash:vlan.

This is how you create a new VLAN. If you want you can give it a name but this is optional. However no ports are currently in VLAN First I will configure the switchport in access mode with the switchport mode access command.

By using the switchport access vlan command we can move our interfaces to another VLAN. Both computers are now in VLAN Explained As Simple As Possible. Full Access to our Lessons. More Lessons Added Every Week! Those commands are all you need to put two interfaces in VLAN The same thing applies to most of the routers. On Frames that are untagged are considered to belong to the native VLAN.

How to configure VLANs on Cisco Catalyst Switch

It is possible to configure your switches to tag the native VLAN btw. There are advantages and disadvantages to creating a trunk between the Router and the Cisco switch. It all depends on what you want to achieve. There are essentially three ways to configure a gateway of last resort on an L3 switch or on a router. These differ in their implementation and their functionality. The ip default-gateway command should only be used when routing is disabled. It essentially tells the device what its default gateway is much like a PC has the default gateway configured.

It is used only for the purposes of connectivity with subnets other than its own. The ip default-network command can be used only when routing is enabled. When you configure ip default-network the. A VLAN is created using the vlan command such as vlan It is an interface that.
