Configuring WLANs
Using the GUI to Configure DHCP
Follow these steps to use the GUI to configure DHCP.
Step 1 In the web user interface, navigate to the WLANs page.
Step 2 Locate the WLAN which you wish to configure for a DHCP server, and click the associated Edit link to
display the WLANs > Edit page.
Step 3 Under General Policies, check the DHCP Relay/DHCP Server IP Addr check box to verify whether
you have a valid DHCP server assigned to the WLAN. If you have no DHCP server assigned to the
WLAN, continue with Step 4. Otherwise, continue with Step 9.
Step 4 Under General Policies, uncheck the Admin Status check box.
Step 5 Click Apply to disable the WLAN.
Step 6 In the DHCP Relay/DHCP Server IP Addr edit box, enter a valid DHCP server IP address for this
WLAN.
Step 7 Under General Policies, check the Admin Status check box.
Step 8 Click Apply to assign the DHCP server to the WLAN and to enable the WLAN. You are returned to the
WLANs page.
Step 9 In the upper-right corner of the WLANs page, click Ping and enter the DHCP server IP address to verify
that the WLAN can communicate with the DHCP server.
Using the CLI to Configure DHCP
Follow these steps to use the CLI to configure DHCP.
Step 1 In the CLI, enter show wlan to verify whether you have a valid DHCP server assigned to the WLAN. If
you have no DHCP server assigned to the WLAN, continue with Step 2. Otherwise, continue with
Step 4.
Step 2 If necessary, use these commands:
• config wlan disable wlan-id
• config wlan dhcp_server wlan-id dhcp-server-ip-address
• config wlan enable wlan-id
In these commands, wlan-id = 1 through 16, and dhcp-server-ip-address = DHCP server IP address.
Step 3 Enter show wlan to verify that you have a DHCP server assigned to the WLAN.
Step 4 Enter ping dhcp-ip-address to verify that the WLAN can communicate with the DHCP server.
