tailieunhanh - Troubleshooting VTP (Troubleshooting LAN Switches)

VLAN Trunk Protocol (VTP) reduces administration in switched networks. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need of configuring the same VLAN everywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst Family products. In this lab you will troubleshoot some basic VLAN trunking problems with VTP (VLAN Trunking Protocol). | Lab Troubleshooting VTP Troubleshooting LAN Switches Fa 2 3 Fa 0 12 Trunk 4006 L3 Crossover Connection ALSwitch 2900XL-Ent Fa 0 1 VLAN 10 Client Objective VLAN Trunk Protocol VTP reduces administration in switched networks.

VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst Family products. In this lab you will troubleshoot some basic VLAN trunking problems with VTP VLAN Trunking Protocol . Scenario This is not part of the International Travel Agency network. As the Enterprise Network Administrator you have a large switched network that is all in the same VTP domain. Your network administrator added a new 2900XL-Enterprise switch to the network. The first connected client to the new switch is from the Accounting Department VLAN 10 . He indicates immediately that he is not able to reach any network resources. The administrator indicated that he did issue the command switchport access vlan 10 on FastEthernet port 0 1 which is the port the Accounting member is connected to and also verified that both the links FastEthernet 0 1 and FastEthernet 0 12 indicate a green connection light on the 2900. FastEthernet 0 12 is designated as the uplink trunking port. Lab Tasks Cable the lab as shown in the diagram.
