how to generate vlan tag

Hi 
below  excerpts  from  the topic " how to generate vlan tag " 


"All the ethernet frames exist in the switch in the form of tagged frames .certain ports may receive untagged frames from peer devices , 
but the frame from the port of the local switch must be a tagged frame .if the frame received is tagged , it will be forwarded ; if it is untagged , 
a tag will be added to it .The device can implement a VLAN in the following way . 


admin configures a a pvid for every port of a switch , known as the port VLAN ID or port default VLAN. if an untagged frame is received , the VLAN ID will be the PVID "


question : what is peer devices mentioned above 


As far as I know  the vlan tag is adding when the frame leaves at the trunk port and the tag will be stripped by the receiving switch .Is that true ?.




Please clarify , i am a newbie in networking

I am not sure what other people are talking about but, whenever an end user device's frame enters the switch through the access port, it will get tagged, either default vlan 1 or whatever default vlan you configured on the access port.
