In an enterprise network, different network access policies can be deployed for users on access devices to meet different network access requirements. The application of mobile office and BYOD technologies brings frequent changes of users' physical locations and IP addresses. Therefore, the original network control solution based on physical ports and IP addresses cannot ensure consistency of network access experience. For example, the network access policy of a user does not change when the user's physical location changes.
The free mobility solution allows a user to obtain the same network access policy regardless of the user's location and IP address changes.
The switches must be associated with the Agile Controller-Campus in the free mobility solution. An administrator only needs to uniformly deploy network access policies on the Agile Controller-Campus for users, and deliver the policies to all associated switches. Then, a user can obtain the same access policy no matter how the user's physical location and IP address change.

When the controller delivers a UCL group name that is not supported by the switch, for example, this group name contains Chinese characters or special characters, the switch cannot parse the group name. A UCL group name that can be supported by the switch must be consistent with the value of group-name in the ucl-group group-index [ name group-name ] command, cannot be -, --, a, an, or any, and cannot contain any of the following characters: / \ : * ? " < > | @ ' %. Therefore, when configuring a UCL group name on the controller, do not use Chinese characters or special characters.
If the core switch has been associated with an Agile Controller-Campus and has free mobility configured, perform the following steps to delete historical data and reconfigure the core switch.
Employees in an enterprise connect to the network in wired and wireless modes and are authenticated using 802.1X or Portal authentication.
The employees do not work in fixed locations and want to obtain the same rights after being authenticated regardless of their access locations.
As shown in Figure 1, the agile core switch coreswitch (supporting native AC) functions as the authentication point and the access switch is a common switch.
You can configure 802.1X authentication and Portal authentication on the core switch so that wired and wireless users can connect to the network after being authenticated by the core switch.
You can configure free mobility so that users have the same rights and experience regardless of their access locations.

Configure the core switch.
Configure the access switch.
Configure the Agile Controller-Campus.
In this example, an access switch exists between users and the core switch functioning as the authentication point, and transparently transmits packets. To ensure that users can pass 802.1X authentication, configure the access switch to transparently transmit 802.1X packets (EAP packets in this example because EAP mode is used).

Choose corresponding to Core_SW to save the configuration.
Saving the configuration is similar to running the save command on the device, which saves all the device configurations (including security groups, access right control policies, and QoS policies deployed on the controller) to the configuration file.
If security groups, access right control policies, and QoS policies are saved to the device's configuration file, these configurations can be directly restored from the configuration file after the device restarts, and do not need to be requested from the controller. Otherwise, user authentication fails after the device restarts because security groups, access right control policies, and QoS policies are not deployed on the device.
Users using accounts in the employee department can access email servers after passing 802.1X or Portal authentication regardless of their access locations.
