With regards to the native VLAN, if you want to use that, you add the native keyword after the VLAN id:

switch(config-if-range)#switchport access vlan 30. 9. Final words. The 'Main Switch' is now divided into 3 switches that we created and itself, as that cannot be removed, viz. Vlan 1; Therefore the original switch is now divided into 4 switches, including itself; Vlan 1 = 'Main Switch' = Ports 9 to 26 + Ports 35 to 40; Vlan 10 = 'Switch 1 ...

Because, the native vlan configured on this switch's trunk port, GigabitEthernet 0/5, is Vlan-1; Result. The ping is successful. Final Notes. Note One.

Also default VLAN, Management-VLAN and Access-VLAN is just "cisco-lingo" and you will see other vendors use other terms for the same purpose. Yes - loops can happen without trunk-ports, in fact they almost always happens due to bad configuration or bad cabling.
