Configuring VLAN Settings for a WLAN SSID Profile

If you are creating a new SSID profile, complete the WLAN Settings procedure before configuring VLAN. For more information, see Configuring WLAN Settings for an SSID Profile.

You can configure VLAN settings for an SSID profile using the Instant UI or CLI.

In the Instant UI

To configure VLAN settings for an SSID:

1. In the VLAN tab of the New WLAN window. The VLAN tab contents are displayed.

Figure 1   VLAN Tab

2. Select any for the following options for Client IP assignment:
Virtual Controller assigned—On selecting this option, the client obtains the IP address from the Virtual Controller.
Network assigned—On selecting this option, the IP address is obtained from the network.
3. Based on the type client IP assignment mode selected, you can configure the VLAN assignment for clients as described in the following table:

Table 1: IP and VLAN Assignment for WLAN SSID Clients

Client IP Assignment Client VLAN Assignment

Virtual Controller assigned

If the Virtual Controller assigned is selected for client IP assignment, the Virtual Controller creates a private subnet and VLAN on the IAP for the wireless clients. The network address translation for all client traffic that goes out of this interface is carried out at the source. This setup eliminates the need for complex VLAN and IP address management for a multi-site wireless network.

On selecting this option, the following client VLAN assignment options are displayed:

l Default: When selected, the default VLAN as determined by the Virtual Controller is assigned for clients.
l Custom: When selected, you can specify a custom VLAN assignment option. You can select an existing DHCP scope for client IP and VLAN assignment or you can create a new DHCP scope by selecting New. For more information on DHCP scopes, see Configuring DHCP Scopes.

Network assigned

If the Network assigned is selected, you can specify any of the following options for the Client VLAN assignment.

l Default— On selecting this option, the client obtains the IP address in the same subnet as the IAPs. By default, the client VLAN is assigned to the native VLAN on the wired network.
l Static— On selecting this option, you need to specify a single VLAN, a comma separated list of VLANS, or a range of VLANs for all clients on this network. Select this option for configuring VLAN pooling.
l Dynamic— On selecting this option, you can assign the VLANs dynamically from a Dynamic Host Configuration Protocol (DHCP) server. To create VLAN assignment rules, click New to assign the user to a VLAN. In the New VLAN Assignment Rule window, enter the following information:
l Attribute— Select an attribute returned by the RADIUS server during authentication.
l Operator— Select an operator for matching the string.
l String— Enter the string to match
l VLAN— Enter the VLAN to be assigned.
4. Click Next to configure security settings for the employee network. For more information, see Configuring Security Settings for a WLAN SSID Profile.

In the CLI

To manually assign VLANs for WLAN SSID users:

(Instant AP)(config)# wlan ssid-profile <name>

(Instant AP)(SSID Profile <name>)# vlan <vlan-ID>

(Instant AP)(SSID Profile <name>)# end

(Instant AP)# commit apply

 

To enforce DHCP-based VLAN assignment:

(Instant AP)(config)# wlan ssid-profile <name>

(Instant AP)(SSID Profile <name>)# enforce-dhcp

(Instant AP)(SSID Profile <name>)# end

(Instant AP)# commit apply

 

To create a new VLAN assignment rule:

(Instant AP)(config)# wlan ssid-profile <name>

(Instant AP)(SSID Profile <name>)# set-vlan <attribute> {{contains|ends-with|equals|matches-regular-expression|not-equals|starts-with} <operand> <vlan>|value-of}

(Instant AP)(SSID Profile <name>)# end

(Instant AP)# commit apply
