4.8. OS X Mountain Lion: Connect to a network that requires 802.1X authentication
You can connect to a Wi-Fi or Ethernet network that is protected by the Institute of Electrical and Electronics Engineers (IEEE) 802.1X standard. The 802.1X standard is designed to enhance the security of local area networks.
In most cases your network administrator provides a configuration profile that contains the information and settings you need to authenticate with the network.
When you download the profile from the web or open the attachment using Mail, the computer recognizes the .mobileconfig extension as a configuration profile and begins installing after you click Install.
During installation, you may be asked to enter any necessary information, such as passwords that weren't specified in the profile, and other information as required. Enter any password necessary to use certificates included in the profile.
- Choose Apple menu > System Preferences, and then click Network.
- Select the network service you want to use, such as Ethernet or Wi-Fi, in the list.
- Click Connect. If you installed multiple profiles, choose the one you want to use from the 802.1X pop-up menu, and then click Connect.
If you are connecting to an Ethernet network that uses 802.1X and want to connect automatically to the network when it's detected, click Advanced, and then click 802.1X. Select "Enable automatic connection."
Ask your network administrator or service provider if you need more information.
