Thus, all devices connected to a port are members of the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire department. On port-based VLANs, NICs do not need to be able to identify 802.1Q tags in packet headers. NICs send and receive normal Ethernet packets. If the packet's destination lies on the same segment, communications take place using normal Ethernet protocols. Even though this is always the case, when the destination for a packet lies on another switch port, VLAN considerations come into play to decide if the packet gets dropped by the Switch or delivered. VLAN Segmentation Take for example a packet that is transmitted by a machine on Port 1 that is a member of VLAN 2. If the destination lies on another port (found through a normal forwarding table lookup), the Switch then looks to see if the other port (Port 10) is a member of VLAN 2 (and can therefore receive VLAN 2 packets). If Port 10 is not a member of VLAN 2, then the packet will be dropped by the Switch and will not reach its destination. If Port 10 is a member of VLAN 2, the packet will go through. This selective forwarding feature based on VLAN criteria is how VLANs segment networks. The key point being that Port 1 will only transmit on VLAN 2. 802.1Q VLAN Settings The VLAN List tab lists all previously configured VLANs by VLAN ID and VLAN Name.

Port-based VLANs

Port-based VLANs limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are

members of the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an

entire department.

On port-based VLANs, NICs do not need to be able to identify 802.1Q tags in packet headers. NICs send and receive

normal Ethernet packets. If the packet’s destination lies on the same segment, communications take place using

normal Ethernet protocols. Even though this is always the case, when the destination for a packet lies on another

switch port, VLAN considerations come into play to decide if the packet gets dropped by the Switch or delivered.

VLAN Segmentation

Take for example a packet that is transmitted by a machine on Port 1 that is a member of VLAN 2. If the destination

lies on another port (found through a normal forwarding table lookup), the Switch then looks to see if the other port

(Port 10) is a member of VLAN 2 (and can therefore receive VLAN 2 packets). If Port 10 is not a member of VLAN 2,

then the packet will be dropped by the Switch and will not reach its destination. If Port 10 is a member of VLAN 2, the

packet will go through. This selective forwarding feature based on VLAN criteria is how VLANs segment networks. The

key point being that Port 1 will only transmit on VLAN 2.
