where the vlan tagging is actually done by switch?

i am little bit confused about tagging on switches. while switch recieves a frame from access port configured as vlan 10. where will the switch tag this vlan to the frame? on trunk port or on access port or is there any other concept behind this? please reply.

thanks in advance.

Hi,

access ports do not tag frame at all and end station connected to this port is unaware which VLAN is assigned to access port.

Between two switches is usually configured trunk. Traffic passing trunk is tagged except of NATIVE VLAN.

Best regards,

Jan
