Configuring AP-based DHCP Service Settings

Using DHCP service settings, you can configure an AP to assign private IP addresses to Wi-Fi clients without the need for a separate DHCP server (router).

1. Go to Services & Profiles > DHCP & NAT.
2. Select the DHCP Setting (AP) tab, and then select the zone for which you want to configure the settings.
3. Select a Zone from the zone list on the left side of the screen, and click Enable DHCP Service on AP.

5. On the first page of the wizard (Base Settings), configure the DHCP Configuration as follows:
   • Enable on Each AP: Each AP in this zone runs its own DHCP server instance. This option is typically used when APs are at different sites and roaming is not required. Now configure the DHCP AP Port Selection by selecting one of the following:
     • Dynamic WAN Port Detection—WAN is automatically identified by default and the LAN will be selected.
     • WAN Port Selection—Manually assign port to WAN and LAN. This setting overrides the original port configuration of a zone. Select the LAN1 and LAN2 options from the drop-down.
   • Enable on Multiple APs: Designate which APs will provide DHCP/NAT service. This option is typically used when multiple APs are at the same site and roaming is required. This option also allows you to choose whether to automatically or manually specify which APs will provide DHCP service. Now configure the DHCP AP Port Selection by selecting one of the following:
     • Dynamic WAN Port Detection—WAN is automatically identified by default and the LAN will be selected.
     • WAN Port Selection—Manually assign port to WAN and LAN. This setting overrides the original port configuration of a zone. Select the LAN1 and LAN2 options from the drop-down.
   • Enable on Hierarchical APs— Designate which APs will provide DHCP/NAT service. The DHCP Server AP connect to the WAN and the other AP get its private IP address from the local IP pool with VLAN ID 1 from the DHCP Server AP. Now configure the DHCP AP Port Selection by selecting one of the following:
     • Dynamic WAN Port Detection—WAN is automatically identified by default and the LAN will be selected.
     • WAN Port Selection—Manually assign port to WAN and LAN. This setting overrides the original port configuration of a zone. Select the LAN1 and LAN2 options from the drop-down.
6. On the next wizard screen, (Select Pools), select up to four DHCP pools from which to assign client IP addresses.
   NOTE

   For the Enable on Hierarchial APs DHCP configuration, one of the pools must be VLAN ID 1.

   NOTE

   If you have not already created DHCP pools, you can do so from within the wizard. Click the Plus (+) icon and configure the IP address pools as described in Creating an AP DHCP Pool.
7. Click Next. The Select APs screen appears.
   NOTE

   If you selected Auto Select AP on the first wizard screen, this configuration screen will be skipped.
8. On the Select APs wizard screen, select the AP(s) that you want to set as the primary and secondary DHCP servers (if you previously selected Enable on Multiple APs).
   NOTE

   For the Enable on Hierarchial APs DHCP configuration, you can select only two APs.
