Configuration Server Protocol
Set this parameter to match the network's method of IP address assignments. Choose DHCP if your network servers are using automatic assignment of IP addresses. Choose Static IP if fixed IP addresses are being assigned. Choose Disable DHCP Address Binding if you require compatibility with older DHCP servers. Normally, you would not check this check box. If you check the check box, no client identifier is sent to the DHCP server. The client identifier is used by the DHCP server to issue consistent IP addresses.
Note: When you configure the access point as a DHCP server, it assigns IP addresses to devices on its subnet. The devices communicate with other devices on the subnet but not beyond it. If data needs to be passed beyond the subnet, you must assign a default router.
Use this setting to assign or change the access point's IP address. If DHCP is not enabled for your network, the IP address you enter in this field is the access point's IP address. If DHCP is enabled, you cannot modify this field.
IP Subnet Mask
Enter an IP subnet mask to identify the subnetwork so the IP address can be recognized on the LAN. If DHCP is not enabled, this field is the subnet mask. If DHCP is enabled, you cannot modify this field.
Default Gateway IP Address
Enter the IP address of the network's default gateway. If DHCP is enabled, you cannot modify this field unless Override DHCP Default Gateway is selected.
Override DHCP Default Gateway
This setting enables you to change the default gateway negotiated by the DHCP server. Enabling this feature might stop traffic to the access point; therefore, Cisco recommends leaving the gateway to the one assigned by the DHCP server.
