Automatic Retrieval of Configuration
This chapter provides the following information:

l Verifying the Configuration on page 26
Managed Mode Operations
W-IAPs support managed mode operations to retrieve the configuration file from a server through the File
Transfer Protocol (FTP) or FTP over Secure Sockets Layer (FTPS), and automatically update the W-IAP
configuration.
The server details for retrieving configuration files are stored in the basic configuration of the W-IAPs. The basic
configuration of a W-IAP includes settings specific to a W-IAP, for example, host name, static IP, and radio
configuration settings. When a W-IAP boots up, it performs a GET operation to retrieve the configuration (.cfg)
file from the associated server using the specified download method.
After the initial configuration is applied to the W-IAPs, the configuration can be changed at any point. You can
configure a polling mechanism to fetch the latest configuration by using an FTP or FTPS client periodically. If
the remote configuration is different from the one running on the W-IAP and if a difference in the
configuration file is detected by the W-IAP, the new configuration is applied. At any given time, W-IAPs can
fetch only one configuration file, which may include the configuration details specific to a W-IAP. For
configuring polling mechanism and downloading configuration files, the users are required to provide
credentials (username and password). However, if automatic mode is enabled, the user credentials required to
fetch the configuration file are automatically generated. To enable automatic configuration of the W-IAPs,
configure the managed mode command parameters.
Prerequisites
Perform the following checks before configuring the managed mode command parameters:
l Ensure that the W-IAP is running Instant 6.2.1.0-3.4 or later versions.
l When the W-IAPs are in the managed mode, ensure that the W-IAPs are not managed by W-AirWave.
