Chapter 4 Wireless LAN Controller Management: Configuring Wireless Out-of-Band Deployment
Overview
The DHCP bridging feature is a global setting, so it affects all DHCP transactions within the controller.
You need to add ip helper statements in the wired infrastructure for all necessary VLANs on the
controller.
You can disable the DHCP proxy through the User Interface as well. In the WLC graphical user interface,
click Controller > Advanced > DHCP and uncheck the Enable DHCP Proxy check box as shown in
Figure 4-1.

Note Setting the DHCP Proxy using GUI is not available in all the versions. You can use the CLI command
to disable the DHCP Proxy.
SNMP Control
In a Wireless OOB deployment, you can add WLCs to the Clean Access Manager’s domain and
communicate with the WLC using the Simple Network Management Protocol (SNMP). SNMP is an
application layer protocol used by network management tools to exchange management information
between network devices. Cisco NAC Appliance and Cisco WLCs support the following SNMP versions
in a Wireless OOB environment:
You first need to configure the WLC to send and receive SNMP traffic to/from the Clean Access
Manager, then configure matching settings on the Clean Access Manager to send and receive traffic
to/from the WLC. This will enable the Clean Access Manager to get VLAN information from the WLC
and coordinate with the WLC when wireless users log out (or are “kicked out”) of the network and
removed from the Online Users list.
