Chapter 4 Configuring Controller Settings
Configuring the Cisco Discovery Protocol
• Power Consumption TLV: 0x0010—The maximum amount of power consumed by the access point.
• Power Request TLV:0x0019—The amount of power to be transmitted by a powerable device in order
to negotiate a suitable power level with the supplier of the network power.
You can configure CDP and view CDP information using the GUI in controller software release 4.1 or
later or the CLI in controller software release 4.0 or later releases. Figure 4-39 shows a sample network
that you can use as a reference when performing the procedures in this section.
Note Changing the CDP configuration on the controller does not change the CDP configuration on the access
points that are connected to the controller. You must enable and disable CDP separately for each access
point.
You can enable or disable the CDP state on all or specific interfaces and radios. This configuration can
be applied to all access points or a specific access point. For more information on how to configure CDP
on the interfaces and radios, see the “Using the GUI to Configure the Cisco Discovery Protocol” section
on page 4-96 and the “Using the CLI to Configure the Cisco Discovery Protocol” section on page 4-102.
The following is the behavior assumed for various interfaces and access points:
• CDP is disabled on radio interfaces on indoor (nonindoor mesh) access points.
• Nonmesh access points have CDPs disabled on radio interfaces when they join the controller. The
persistent CDP configuration is used for the APs that had CDP support in its previous image.
• CDP is enabled on radio interfaces on indoor-mesh and mesh access points.
• Mesh access points will have CDP enabled on their radio interfaces when they join the controller.
The persistent CDP configuration is used for the access points that had CDP support in a previous
image. The CDP configuration for radio interfaces is applicable only for mesh APs.
