are the defaults. This switch is capable of running version 1, 2 or 3 of VTP and runs version 1 by default. All switches in the VTP domain must run the same VTP version. The VTP mode is set to Transparent as a result of steps performed in Lab 1. The number of existing VLANs is the five built-in VLANs. Different switches in the Catalyst family support different numbers of local VLANs. The 3560 switch used in this lab supports a maximum of 1,005 VLANs locally, while the 2960 switch used in this lab supports at most 255 VLANs. Lastly, note that the configuration revision is 0. As you should recall from CCNA, the configuration revision number is compared amongst VTPv1 or VTPv2 switches and the VLAN database from the switch with the highest revision number is adopted by all the other switches in the VLAN management domain. Every time VLAN information is modified and saved in the VLAN database (vlan.dat), the revision number is increased by one when the user exits from VLAN configuration mode. In VTPv3, revision numbers are still used but they no longer determine the switch whose database is going to apply to the entire domain. Instead, a single designated switch in a VTP domain called the primary server is allowed to assert its database in the entire VTP domain, even if its own revision number is lower. Other switches that are not primary servers are not allowed to assert their databases even if their revision numbers are higher. Multiple switches in the VTP domain can be in VTP server mode. In VTPv1 and VTPv2, any of these server switches can be used to manage all other switches in the VTP domain. In VTPv3, a single primary server for a particular VTP domain is designated to control where changes originate from in the switched network. This enables careful management and protection of the VLAN database. Step 2: Configure VTP on DLS1. We will start off this lab by configuring DLS1 for VTP Server mode and setting the VTP domain name and VTP version 2. We will also set a VTP password, which provides some rudimentary protection against © 2014 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 5 of 20
