!--- Configure IEEE 802.1 (dot1q) trunking, with negotiation, on the L2 switch.
!--- If there is not support for Dynamic Trunking Protocol (DTP) on the far switch,
!--- issue the switchport mode trunk command to force the switch port to trunk mode.
!--- Note: The default trunking mode is dynamic auto. If you establish a trunk link
!--- with the default trunking mode, the trunk does not appear
!--- in the configuration, even though a trunk has been established on
!--- the interface. Use the show interfaces trunk command to verify the
!--- establishment of the trunk.

Note: Since the 3550 has configuration as a VLAN Trunk Protocol (VTP) server, the switch does not display the VTP configuration. This behavior is standard. This switch uses these commands to create a VTP server with the three VLANs that the user defined from global configuration mode:
Cat3550(config)#vtp domain cisco
Cat3550(config)#vtp mode server
Cat3550(config)#vlan 2
Cat3550(config-vlan)#name USER_VLAN
Cat3550(config-vlan)#exit
Cat3550(config)#vlan 3
Cat3550(config-vlan)#name SERVER_VLAN
Cat3550(config-vlan)#exit
Cat3550(config)#vlan 10
Cat3550(config-vlan)#name MANAGEMENT
Thanks
