Use the information that is described in this section in order to register a Cisco wireless phones with the CUCM server.
Access Point Configuration
How to Access the Access Point (AP)
Configure DHCP on your L3 Switch or ensure that the switch to which the Aironet will be connected has access to the DHCP server.
After you connect the Aironet to the switchport of a Cisco switch, you can find the Aironet’s details by using show cdp neighbors command on switch.
In order to find out the IP address of the Aironet (which would have taken via DHCP), use the command show cdp neighbors fa 0/6 detail on the switch.
Default username and passwords for the Aironet will be Cisco and Cisco.
