Configuring the Access Point
to Provide DHCP Service
By default, access points are configured to receive IP settings from a DHCP
server on your network. You can also configure an access point to act as a DHCP
server to assign IP settings to devices on both your wired and wireless LANs.
For detailed information on commands related to DHCP commands and
options, see
Setting up the DHCP Server
Beginning in privileged EXEC mode, follow these steps to configure an access
point to provide DHCP service and specify a default router:
1. Enter global configuration mode.
configure terminal
2. Exclude the wireless device IP address from the range of addresses the
wireless device assigns. Enter the IP address in four groups of characters,
such as 10.91.6.158.
The wireless device assumes that all IP addresses in a DHCP address pool
subnet are available for assigning to DHCP clients. You must specify the
IP addresses that the DHCP Server must not assign to clients.
(Optional) To enter a range of excluded addresses, enter the address at the
low end of the range followed by the address at the high end of the range.
ip dhcp excluded-address low_address [ high_address
]
3. Create a name for the pool of IP addresses that the wireless device assigns
in response to DHCP requests, and enter DHCP configuration mode.
ip dhcp pool pool_name
4. Assign the subnet number for the address pool. The wireless device assigns
IP addresses within this subnet.
(Optional) Assign a subnet mask for the address pool, or specify the
number of bits that comprise the address prefix. The prefix is an alternative
way of assigning the network mask. The prefix length must be preceded by
a forward slash (/).
network subnet_number
[ mask | prefix-length ]
TIP
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. The IP address of the default router must be on
the same subnet as the access point configured as the DHCP server.
