Dynamically Assigning Ports to VLANs
In the initial VLAN port assignment configuration shown below,
•
All three ports have workstations that are configured to send packets with an 802.1Q VLAN ID tag for
three different VLANs (VLAN 2, 3, and 4).
•
Mobility is enabled on each of the workstation ports.
•
VLAN 1 is the configured default VLAN for each port.
•
VLANs 2, 3, and 4 are configured on the switch, each one has VLAN mobile tagging enabled.

Port 1
VLAN ID Tag = 2
As soon as the workstations start sending traffic, switch software checks the 802.1Q VLAN ID tag of the
frames and looks for a VLAN that has the same ID and also has mobile tagging enabled. Since the work-
stations are sending tagged packets destined for the mobile tag enabled VLANs, each port is assigned to
the appropriate VLAN without user intervention. As the diagram on
•
Port 1 is assigned to VLAN 2, because the workstation is transmitting tagged packets destined for
VLAN 2.
•
Port 2 is assigned to VLAN 3 because the workstation is transmitting tagged packets destined for
VLAN 3.
•
Port 3 is assigned to VLAN 4 because the workstation is transmitting tagged packets destined for
VLAN 4.
•
All three ports, however, retain their default VLAN 1 assignment, but now have an additional VLAN
port assignment that carries the matching traffic on the appropriate rule VLAN.
