Configuring VLANs Defining VLAN Port Assignments

Configuring Dynamic VLAN Port Assignment
Configuring the switch to allow dynamic VLAN port assignment requires the following steps:
1 Use the vlan port mobile command to enable mobility on switch ports that will participate in dynamic
VLAN assignment. See Chapter 6, “Assigning Ports to VLANs,”for detailed procedures.
2 Enable/disable mobile port properties that determine mobile port behavior. See Chapter 6, “Assigning
Ports to VLANs,” for detailed procedures.
3 Create VLANs that will receive and forward mobile port traffic. See “Adding/Removing a VLAN” on
page 4-6 for more information.
4 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 “Configuring VLAN Rule Clas-
sification” on page 4-9 and “Enabling/Disabling VLAN Mobile Tag Classification” on page 4-10.
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.
See Chapter 6, “Assigning Ports to VLANs,” and Chapter 8, “Defining VLAN Rules,” for more informa-
tion and examples of dynamic VLAN port assignment.
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 Chapter 8, “Defining VLAN Rules.”
