Enable environmental variables
After you have the configuration information file ready and hosted on the SCP server, you need to
configure the following environmental variables.
You can configure the environmental variables by using the following command in global configuration
mode:
dot11 autoconfigadd environment-variable-name val value.
For example:
dot11 autoconfig add AUTO_CONFIG_SERVER val 206.59.246.199

After setting the environmental variables, you need to schedule the download of the configuration
information file from the SCP server. Follow these steps:

the SNTP server using the command, sntp serversntp-server-ip, where sntp-server-ip is the IP address
of the SNTP server.
