Autonomous: Configure A Cisco AP To Provide DHCP Services
1. Lets start with the client exclusion. We will exclude the following ranges, so that the AP doesn't
assign these specific addresses out:
assign these specific addresses out:
192.168.1.1 - 192.168.1.10
192.168.1.200 - 192.168.1.254
192.168.1.200 - 192.168.1.254
ap#config t
ap(config)#ip dhcp excluded-address 192.168.1.1 192.168.1.10
ap(config)#ip dhcp excluded-address 192.168.1.200 192.168.1.254
2. Next, we will name the DHCP Scope (pool) and set the network:
ap(config)#ip dhcp pool WIRELESS
ap(dhcp-config)#network 192.168.1.0
ap(dhcp-config)#network 192.168.1.0
3. Next, we will set the LEASE time for the addresses (3 days,4 hours, 20 min) , setup the gateway and DNS:
ap(dhcp-config)#lease 3 4 20
ap(dhcp-config)#default-router 192.168.1.1
ap(dhcp-config)#dns-server 192.168.1.250
ap(dhcp-config)#default-router 192.168.1.1
ap(dhcp-config)#dns-server 192.168.1.250
4. Next, we connect a wired laptop to the switch on the VLAN and see the results:
(Note this will also hand out Wireless DHCP as well)
