Configuring Dynamic VLAN Port Assignment
Configuring the switch to allow dynamic VLAN port assignment requires the following steps:
Use the 
 command to enable mobility on switch ports that will participate in dynamic 
VLAN assignment. See 
for detailed procedures.
Enable/disable mobile port properties that determine mobile port behavior. See 
 for detailed procedures.
Create VLANs that will receive and forward mobile port traffic. See 
 for more information.
Configure the method of traffic classification (VLAN rules or tagged VLAN ID) that will trigger 
dynamic assignment of mobile ports to the VLANs created in Step 3. See 
Once the above configuration steps are completed, dynamic VLAN assignment occurs when a device 
connected to a mobile port starts to send traffic. This traffic is examined by switch software to determine 
which VLAN should carry the traffic based on the type of classification, if any, defined for a particular 
VLAN.
Note that VLAN mobile tag classification takes precedence over VLAN rule classification. If a mobile 
port receives traffic that matches a VLAN rule and also has an 802.1Q VLAN ID tag for a VLAN with 
mobile tagging enabled, the port is dynamically assigned to the mobile tag VLAN and not the matching 
rule VLAN.

Configuring VLAN Rule Classification
VLAN rule classification triggers dynamic VLAN port assignment when traffic received on a mobile port 
matches the criteria defined in a VLAN rule. Different rule types are available for classifying different 
types of network device traffic. It is possible to define multiple rules for one VLAN and rules for multiple 
VLANs. 
The following table provides a list of commands used to define the various types of VLAN rules. For 
more detailed information about rule criteria and classification, see
