Configuring WLANs
Step 6 On the General tab, choose the interface for which you configured a primary DHCP server to be used
with this WLAN from the Interface drop-down box.
Step 7 Click the Advanced tab to open the WLANs > Edit (Advanced) page.
Step 8 If you want to define a DHCP server on the WLAN that will override the DHCP server address on the
interface assigned to the WLAN, check the DHCP Server Override check box and enter the IP address
of the desired DHCP server in the DHCP Server IP Addr edit box. The default value for the check box
is disabled.
Note The preferred method for configuring DHCP is to use the primary DHCP address assigned to a
particular interface instead of the DHCP server override.
Step 9 If you want to require all clients to obtain their IP addresses from a DHCP server, check the DHCP Addr.
Assignment Required check box. When this feature is enabled, any client with a static IP address is not
allowed on the network. The default value is disabled.
Step 10 Click Apply to commit your changes.
Step 11 On the General tab, check the Status check box and click Apply to re-enable the WLAN.
Step 12 Click Save Configuration to save your changes.
Using the CLI to Configure DHCP
Follow these steps to configure DHCP using the CLI.
Step 1 Follow the instructions in the “Using the GUI to Configure the Management, AP-Manager, Virtual, and
Service-Port Interfaces” section on page 3-11 or “Using the GUI to Configure Dynamic Interfaces”
section on page 3-16 to configure a primary DHCP server for a management, AP-manager, or dynamic
interface that will be assigned to the WLAN.
Step 2 To disable the WLAN, enter this command:
config wlan disable wlan_id
Step 3 To specify the interface for which you configured a primary DHCP server to be used with this WLAN,
enter this command:
config wlan interface wlan_id interface_name
Step 4 If you want to define a DHCP server on the WLAN that will override the DHCP server address on the
interface assigned to the WLAN, enter this command:
config wlan dhcp_server wlan_id dhcp_server_ip_address
Note The preferred method for configuring DHCP is to use the primary DHCP address assigned to a
particular interface instead of the DHCP server override. If you enable the override, you can use
the show wlan command to verify that the DHCP server has been assigned to the WLAN.
Step 5 To re-enable the WLAN, enter this command:
config wlan enable wlan_id
