Is there a way to allow the transport of a 802.1q trunk connection on ports configured as access ports ? In other words on an existing switched environnement you define a vlan with access ports and you interconnect two other switches using 802.1q trunk protocol . So that the initial switches act as strictly layer two transport switches with respect to the second pair of switches.
Not sure if I understand the question clearly but it sounds like you already know to use the 'switchport mode trunk' command on the links that go back to other dot1q switches.
Access ports to me (according to the CCDA definition) are user ports on an access layer switch. If that is the case, I don't know why you would want trunking done on these ports. But like I said before, if your goal is to configure certain ports on a switch to be trunk ports then you use the config t, interface fastethernet 0/1, switchport mode trunk command

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
