Wi-Fi Array
Configuring the Wi-Fi Array 189
CDP Settings
CDP (Cisco Discovery Protocol) is a layer 2 network protocol used to share
information (such as the device manufacturer and model, network capabilities,
and IP address) with other directly connected network devices. Wi-Fi Arrays can
both advertise their presence by sending CDP announcements, and gather and
display information sent by neighbors (see “CDP Neighbors” on page 140).
This window allows you to establish your CDP settings. When finished, click on
the Apply button to apply the new settings to this session, or click Save to apply
your changes and make them permanent.

Procedure for Configuring CDP Settings
1. Enable CDP: When CDP is enabled, the Array sends out CDP
announcements of the Array’s presence, and gathers CDP data sent by
neighbors. When disabled, it does neither. CDP is enabled by default.
2. CDP Interval: The Array sends out CDP announcements advertising its
presence at this interval. The default is 60 seconds.
3. CDP Hold Time: CDP information received from neighbors is retained
for this period of time before aging out of the Array’s neighbor list. Thus,
if a neighbor stops sending announcements, it will no longer appear on
the CDP Neighbors window after CDP Hold Time seconds from its last
announcement. The default is 180 seconds.
