Assigning traffic to a VLAN
You can assign wireless traffic to a VLAN for an entire VSC or for individual users.
Note A VLAN that is assigned to a user overrides a VLAN assigned by a VSC or by the default VLAN.
Assigning a VLAN to a VSC
You can map each VSC to its own VLAN. Wireless clients that connect to a VSC with VLAN support are bridged to the appropriate VLAN. Address allocation and security measures are the responsibility of the target network to which the VLAN connects.
Note You cannot assign the same VLAN ID to the default VLAN and to a VLAN that is mapped to a virtual service community.
For information on how to assign a VLAN to a VSC, see Egress VLAN on page 2-10.
Assigning VLANs to individual users
You can assign a VLAN to an individual user by setting attributes in the user’s RADIUS account. Restrictions are as follows: ? A user cannot be assigned to a VLAN that is set as the default VLAN on port 1 or port 2. ? A user can only be assigned to a predefined VLAN. ? Only applicable to 802.1X client stations. (Not applicable to MAC authentication.) For more information see Configuring user accounts on a RADIUS server on page 6-5.
VLAN bridging
If you assign a VLAN ID to more than one interface, the VLAN is bridged across the interfaces.
For example, if you create the VLANs shown in the following table, all VLAN traffic with ID 50 is bridged across all these interfaces. If you create a VSC and assign the egress VLAN to any of these VLANs, output from the VSC can be sent to any interface.
VLAN configuration
To view and configure VLAN definitions, select Network > Ports and look in the VLAN configuration box:
To add a VLAN, click Add New VLAN. The Add/Edit VLAN page opens.
Define VLAN settings according to the information provided in the following sections.
VLAN support
General ? Port: Select the physical interface with which the VLAN is associated.
? VLAN ID: Specify a VLAN identifier. If the VLAN is assigned to port 1 or port 2, you can also define a range of VLANs in the form X-Y, where X and Y can be 1 to 4094. For example, 50-60. This enables a single VLAN definition to accept traffic for one or more VLAN IDs, making it easy to manage a large number of contiguously assigned VLANs. You can define more than one VLAN range, but each range must be distinct.
Note VLANS with ranges cannot be used for VSC egress mapping and cannot be assigned an IP address.
? VLAN name: Specify a name to identify the VLAN definition on the AP. This name has no operational significance.
Assign IP address via
Specify how the VLAN obtains an IP address, as follows:
? DHCP client: Available only on VLANs that are assigned to port 1 or port 2. The VLAN obtains its IP address from a DHCP server on the same VLAN. There is no support for obtaining a default gateway from the DHCP server.
? Static: Enables you to manually assign an IP address to the VLAN. If you select this option, you must specify a static IP address, Mask, and Gateway.
? None: Specifies that this VLAN has no IP address. Use this option when the VLAN ID is defined as a range.
