what is the command to enter vlan interface configuration mode for s1

This tutorial explains how to create and assign VLAN, VLAN Membership (Static and Dynamic), Router on Stick and Spanning Tree Protocol (STP) in particular with practical examples in packet tracer. Larn how to create and manage VLAN in Cisco switch footstep by step.

Create a practice lab in parcel tracer as shown in post-obit effigy or download pre-created practice lab from second part of this tutorial.

This is the last part of our article "VLAN, VTP, DTP, STP and Router on Stick Explained with Examples". Y'all can read other parts of this article hither:-

VLAN Basic Concept Explained with Examples

This is the first office of this article. In this role nosotros explained bones concepts of VLAN such equally What VLAN is, Advantage of VLAN, VLAN membership Static and Dynamic, VLAN Connections; Admission link and body links, trunk tagging and how VLAN add additional layer of security with examples.

VLAN Practice LAB Setup on Packet Tracer

This is the second function of this article. In this function we explained how to create a practice lab in Package Tracer. You can create practice lab by following the education or alternatively download pre created lab. This lab volition we used to demonstrate the configuration office of VLAN, VTP, DTP, STP and router on stick.

Configure VTP Server and Client in Switch

This the 3rd part of this commodity. In this part we explained VTP mode with examples including VTP Server mode, VTP Client mode and VTP transparent mode. Afterward nosotros configured VTP protocol in our practise lab.

VLAN Tagging Explained with DTP Protocol

This the 4th office of this article. In this part we explained admission link, trunk link, VLAN tagging process, VLAN tagging protocol ISL and 802.1Q, Dynamic trunking protocol and DTP manner with examples. Later in this part we configured trunking in our practice lab.

Creating VLAN

In practice lab network Office1 Switch is configured as VTP Server. Office2 and Office3 switches are configured as VTP clients. We only need to create VLANs in VTP Server. VTP Server will propagate this information to all VTP clients automatically.

vlan vlan number control is used to create the VLAN.

Role 1 Switch

S1(config)#vlan ten S1(config-vlan)#go out S1(config)#vlan 20 S1(config-vlan)#go out S1(config)#          

Assigning VLAN Membership

VLAN tin be assigned statically or dynamically. CCNA test but includes static method; therefore we will besides apply static method to assign VLAN membership. switchport admission vlan [vlan number ] command is used to assign VLAN to the interface. Post-obit commands volition assign VLANs to the interfaces.

Office 1 Switch

S1(config)#interface fastEthernet 0/1 S1(config-if)#switchport access vlan 10 S1(config-if)#interface fastEthernet 0/ii S1(config-if)#switchport access vlan 20          

Part 2 Switch

S2(config)#interface fastEthernet 0/1 S2(config-if)#switchport access vlan 10 S2(config-if)#interface fastEthernet 0/2 S2(config-if)#switchport access vlan 20          

Office 3 Switch

S3(config)#interface fastEthernet 0/1 S3(config-if)#switchport access vlan 10 S3(config-if)#interface fastEthernet 0/two S3(config-if)#switchport access vlan 20          

Nosotros accept successfully assigned VLAN membership. It's time to test our configuration. To test this configuration, we volition apply ping control. ping command is used to test connectivity between two devices. 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.

Testing VLAN configuration

Access PC's command prompt to test VLAN configuration. Double click PC-PT and click Control Prompt

Nosotros have two VLAN configurations VLAN 10 and VLAN 20. Permit's test VLAN 10 commencement. In VLAN 10 we accept three PCs with IP addresses 10.0.0.2, x.0.0.three and 10.0.0.4. These PCs must be able to communicate with each other's. At this betoken PCs from VLAN 10 should non exist immune to access PCs from VLAN twenty. VLAN 20 as well has three PCs twenty.0.0.ii, 20.0.0.iii and 20.0.0.4.

We have successfully implemented VLAN 10 now test VLAN 20.

Same as VLAN x, PCs from VLAN 20 must exist able to communicate with other PCs of same VLAN while they should not be able to admission VLAN x.

Congratulations nosotros accept successfully achieved i more mile stones of this article.

Configure Router on Stick

Typically routers are configured to receive data on ane concrete interface and forward that data from another concrete interface based on its configuration. Each VLAN has a layer 3 address that should be configured as default gateway accost on all its devices. In our scenario we reserved IP address 10.0.0.1 for VLAN x and 20.0.0.1 for VLAN 20.

With default configuration we demand two physical interfaces on router to brand this intra VLAN advice. Due to price of router, information technology's not a toll effective solution to utilise a physical interface of router for each VLAN. Usually a router has one or 2 Ethernet interface. For instance if we have fifty VLANs, we would need virtually 25 routers in lodge to brand intra VLANs communications. To deal with state of affairs we use Router on Stick.

Router on Stick is router that supports trunk connection and has an power to switch frames between the VLANs on this torso connectedness. On this router, unmarried physical interface is sufficient to make communication between our both VLANs.

Admission command prompt of Router

To configure Router on Stick we accept to admission CLI prompt of Router. Click Router and Click CLI from menu items and Printing Enter key to access the CLI

Run following commands in same sequence to configure Router on Stick

Router>enable Router#configure last Enter configuration commands, ane per line.  End with CNTL/Z. Router(config)#interface fastEthernet 0/0 Router(config-if)#no ip address Router(config-if)#no shutdown Router(config-if)#leave Router(config)#interface fastEthernet 0/0.10 Router(config-subif)#encapsulation dot1Q ten Router(config-subif)#ip address ten.0.0.1 255.0.0.0 Router(config-subif)#exit Router(config)#interface fastEthernet 0/0.xx Router(config-subif)#encapsulation dot1Q xx Router(config-subif)#ip address 20.0.0.1 255.0.0.0 Router(config-subif)#exit          

• In above configuration nosotros broke up single physical interface [FastEthernet 0/0] into two logical interfaces, known equally sub-interfaces. Router supports up to 1000 interfaces including both physical and logical.
• By default interface link works as admission link. We need to modify it into trunk link. encapsulation commands specify the trunk type and associate VLAN with sub-interface.
• In next stride we assigned IP accost to our sub-interface.

That's all configuration nosotros demand to switch VLANs. Now we can test different VLAN communications. To test intra VLANs communication open command prompt of PC and ping the PC of other VLAN.

PC [10.0.0.3] from VLAN 10 can now access PC [20.0.0.2] from VLAN 20.

Spanning Tree Protocol (STP)

STP is a layer two protocol, used for removing loops. For backup purpose we typically create backup links for important resources. In our scenario, all offices have fill-in links that create loops in topology. STP automatically removes layer 2 loops. STP multicasts frame that contain data virtually switch interfaces. These frames are called BPDU (Bridge Protocol Data Units). Switch utilise BPDUs to learn network topology. If it found any loop, it volition automatically remove that. To remove loop, STP disables port or ports that are causing it.
