Q. Which lightweight access points (LAPs) do the 4100 Series Controllers support?

A. Only the Airespace 1200, 1250, the Cisco 1000 Series, and the Cisco 1500 Series LAPs work with the earlier 4100 Series Controllers.

Q. I have a Cisco Adaptive Security Appliance (ASA) device. Can I use this ASA as a DHCP server instead of windows DHCP server in order to assign IP addresses to my lightweight access points (LAPs)?

A. No, it is not possible to use an ASA as a DHCP server for LAPs. This is because the DHCP requests from the LAPs are forwarded to the external DHCP server through the WLC. Therefore, a WLC acts as a DHCP relay agent to forward the request from the LAP. However, ASA does not support DHCP requests from a DHCP relay agent.

If ASA is configured as a DHCP server, you cannot configure DHCP relay services on an interface on which the server is enabled. Additionally, DHCP clients must be directly connected to the interface on which the server is enabled. Refer to PIX/ASA as a DHCP Server and Client Configuration Example for more information.

The Cisco ASA combines the functions of a firewall, Virtual Private Network (VPN), and intrusion prevention system (IPS) in a single appliance. The ASA is managed by an easy−to−use Adaptive Security Device Manager (ASDM).

Q. Is it possible to go back and make corrections in the wireless LAN controller (WLC) configuration wizard at the time of the initial configuration?

A. Yes, this can be done with the (hyphen) key. Use this key to re−enter the previous parameter value.

For example, you use the WLC configuration wizard in order to configure the WLC from scratch.

Instead of entering the username as admin, you enter it as adminn. In order to correct this, enter (hyphen key) at the next prompt, then click Enter. The system returns to the previous parameter.

Use the '−' character to backup

System Name [Cisco_e8:38:c0]: adminn

Enter Administrative User Name (24 characters max): −

System Name [Cisco_e8:38:c0] (31 characters max):

Q. In accordance to RFC 1907 for Simple Network Management Protocol (SNMP), the SNMP location field should support a size from 1−255. However, I am unable to enter more than 31 characters in the SNMP location field. Why?
