Cisco Catalyst - skip any VLANs without VTP and VLAN Database?
UPD: I realized that this does not work:
If you transfer to Cisco Catalyst under IOS in VTP Transparent Mode, do you still need to register VLANs in the VLAN database, or will it skip everything that is allowed in switcport trunk allowed vlan?
Problem statement:
Configure a stand-alone C3560 so that it still switches any VLANs (switchport trunk vlan allowed all) without having to climb and register each VLAN in the vlan database. In the most simple way, without complicating the config.
Thank you.

Make a QinQ port on any vlan there. Then through these ports it is possible to carry out any vlana.
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# vlan 10
switch(config-vlan)# no shutdown
switch(config-vlan)# no ip igmp snooping
switch(config-vlan)# exit
switch(config)# interface ethernet 7/1
switch(config-if )# switchport
switch(config-if)# switchport mode dot1q-tunnel
switch(config-if)# switchport access vlan 10
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)# exit
apcsb Essentially, VTP Transparent Mode resets the VTP synchronization counter, i.e. you are moving in the wrong direction. Here's how to do it:
Before you connect the new switch to the network, change the VTP mode of the switch to Transparent. This resets the Configuration Revision number to zero ('0').
Connect the switch to the network and configure the appropriate trunk links.
Configure the VTP attributes:
Configure the VTP domain name to match the VTP domain name of the network.
Configure the VTP version and password (if any required).
Verify if all required VLANs are available in the new switch and in the VTP servers of the network.
Change the VTP mode to Client.
The Configuration Revision number is still zero ('0'). VLANs start to propagate from the VTP server(s) that exists in the network.
If any VLAN is missing, a quick workaround is to add it from one of the VTP servers.
