Trunk is used for transmission of information and vtp vlan information.
Layer 2 switches have two distribution vlan10, if these two vlan10 communication link between the two switches will be configured adapter trunk mouth. I will go out of the trunk because the data packet encapsulation dot1q or ISL. Reached so that a packet switches is another switch can take months to identify the vlan.
There is a machine that can work in the trunk, I Can two switches on the side dubbed trunk even while dubbed access, the two sides can vlan communication? ? ! !
