VLAN Configuration 
VLAN Overview 
A Virtual LAN (VLAN) is a logical network gr ouping that limits the broadcast domain. It 
allows you to isolate network traffic so only  members of the VLAN receive traffic from 
the same VLAN members. Basically, creati ng a VLAN from a switch is logically 
equivalent of reconnecting a group of ne twork devices to another Layer 2 switch. 
However, all the network devices are still  plug...

Tagging - The act of putting 802.1Q VLAN information into the header of a packet. 
Untagging - The act of stripping 802.1Q VLAN  information out of the packet header. 
•  802.1Q VLAN Tags 
The figure below shows the 802.1Q VLAN  tag. There are four additional octets 
inserted after the source MAC address. Thei r presence is indicated by a value of 
0x8100 in the Ether Type field. When a packe ts Ether Type field is equal...

•  Port VLAN ID 
Packets that are tagged (are carrying the 802. 1Q VID information) can be transmitted 
from one 802.1Q compliant network device  to another with the VLAN information 
intact. This allows 802.1Q VLAN to span  network devices (and indeed, the entire 
network - if all network devices are 802.1Q compliant). 
Every physical port on a switch has a PVID.  802.1Q ports are also assigned a PVID, for 
use within...

Link Type is set as Trunk Link and 
Hybrid Link. Assign a number  in the range between 1 an 4094. 
 
NOTE: Access Link: 
Because the access port doesnt have an  understanding of tagged frame, the column 
field of Tagged VID is not available. 
 
NOTE:  Trunk Link
