VLAN: How are packets distributed with respect to the different classifications?
traffic that assigned native vlan
Hubs segregate packets because hubs are used as switches. Through a VLAN, hubs, when used as switches, can easily segregate incoming and outgoing traffic.
The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.
traffic that assigned native vlan
A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. The pvid places the port into the set of ports that are connected under the designated VLAN ID. Also, if a trunk port has not been configured with any VLAN memberships, the virtual switch's Port VLAN ID (pvid) becomes the default VLAN ID for the ports connection.
The frames are assigned to the native VLAN.
VLANs provide the capability so virtually segregate traffic on a network. VLANs work by tagging traffic packets and ensuring that packets with separate VLAN IDs are only available at ports which have been configured for that VLAN ID.
... an access port, which carries traffic only to and from the specific VLAN assigned to it. Contrast with 'trunk port' See http://searchnetworking.techtarget.com/definition/trunk
If a switch receives a frame (a piece of data) from a certain port, it will identify that as belonging to a certain VLAN, because each port is assigned a certain port.In a trunk link, additional data is added to each frame (frame tagging), to identify to which VLAN each frame belongs.
Performance is increased by keeping all users in the same Layer 2 network
• Access link: An access link is a link that is part of only one VLAN, and normally access links are for end devices. Any device attached to an access link is unaware of a VLAN membership. An access-link connection can understand only standard Ethernet frames. Switches remove any VLAN information from the frame before it is sent to an access-link device.• Trunk link: A Trunk link can carry multiple VLAN traffic and normally a trunk link is used to connect switches to other switches or to routers. To identify the VLAN that a frame belongs to, Cisco switches support different identification techniques (VLAN Frame tagging). Our focus for CCNA examination is on Inter-Switch Link (ISL) and 802.1Q.A trunk link is not assigned to a specific VLAN. Many VLAN traffic can be transported between switches using a single physical trunk link.
Since VLAN's cannot communicate with other VLAN's directly, I believe you would have to set up a router to do that. I would check out how to set up a bridge between two VLAN's.
