Jeremy’s IT Lab: CCNA Lecture

Introduction

• Free, complete course for CCNA.
• Encouragement to subscribe, like, comment, and share.
• Practice lab available; recommended to use Packet Tracer and Boson’s NetSim for advanced simulation.

Lab Overview

• Focus on DTP (Dynamic Trunking Protocol) and VTP (VLAN Trunking Protocol).
• 4 VLANs: VLAN10, VLAN20, VLAN30, VLAN40.
• Using VTP for VLAN configuration sharing.

Step 1: Configure Switchports as Trunks

• SW1

  • Enter privileged and global config mode.
  • Check interface G0/1.
  • Default mode: dynamic auto, operational mode: static access.
  • Configure as trunk: SWITCHPORT MODE TRUNK.
  • Disable DTP: SWITCHPORT NONEGOTIATE.

• SW2

  • Configure G0/1 and G0/2 as trunks and disable DTP using interface range.
  • Check configuration using DO SHOW INTERFACE command.

• SW3

  • Configure G0/1 as trunk and disable DTP.

Step 2: Configure VTP on SW1

• Check current VTP status.
• Version 1 operating, domain name is blank.
• Set VTP domain name: VTP DOMAIN CCNA.
• Create VLANs 10, 20, 30.
• Verify VLAN creation and VTP revision number.

Step 3: VTP Transparent Mode on SW2

• Configure SW2 to transparent mode: VTP MODE TRANSPARENT.
• Add VLAN40.
• Verification shows SW1 and SW3 do not have VLAN40 as SW2 does not send VTP advertisements.

Step 4: Configure SW3 in Client Mode

• Set SW3 to VTP client: VTP MODE CLIENT.
• Attempt to add VLAN50 fails as client mode does not allow local VLAN creation.

Step 5: Configure Access Ports

• SW3

  • F0/1 in VLAN10, F0/2-3 in VLAN30, F0/4 in VLAN20.
  • Disable DTP by setting ports to access mode.

• SW2 and SW1

  • SW2: F0/1-2 in VLAN40.
  • SW1: F0/1-2 in VLAN10, F0/3 in VLAN20.

Boson NetSim Lab Preview

• Simple lab: Configuring VTP Client Mode.
• Steps include setting hostnames, configuring interfaces as trunks, and setting VTP domain.
• Verification steps included.

Additional VTP Feature: VTP Password

• SW1 set with VTP password cisco.
• VLAN50 created and tested for synchronization with SW3.
• Incorrect password does not allow sync.
• Correct password results in successful sync.
