Goal: Setting up VTP, Setting up DTP, Adding VLANs and Assigning Ports, Setting up an Extended VLAN
All switches use VTP for VLAN updates. S2 is configured as VTP server, S1 and S3 as clients.
Part 4 switches S1 to VTP transparent mode and creates an extended-range VLAN.
S1
enable
configure terminal
interface vlan 1

Disable DNS lookup, set passwords, enable logging synchronous:

no ip domain-lookup
enable secret cisco
