Managing AP Whitelists

Campus or Remote APs appear as valid APs in the Campus AP or Remote AP whitelists when you manually enter their information into the Campus AP or Remote AP whitelists using the WebUI or CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. of a controller. Also, the Campus APs or Remote APs appear as valid APs after a controller sends a certificate to an AP as part of automatic certificate provisioning and the AP connects to the controller over a secure tunnel. APs that are not approved or certified on the network are included in the Campus AP whitelists, but these APs appear in an unapproved state.

Use the AP whitelists to grant valid APs secure access to the network or to revoke access from suspected rogue APs. When you revoke or remove an AP from the Campus AP or Remote AP whitelists on a controller that uses CPsec Control Plane Security. CPsec is a secure form of communication between a controller and APs to protect the control plane communications. This is performed by means of using public-key self-signed certificates created by each master controller. , that AP will not able to communicate with the controller again, unless the AP obtains a new certificate.

The following sections discuss the procedures to manage AP whitelists:

Revoking an AP from the Campus AP Whitelist

You can revoke an invalid or rogue AP either by modifying its revoke status (as described in Modifying an AP in the Campus AP Whitelist) or by directly revoking it from the Campus AP whitelist without modifying any other parameter. When revoking an invalid or rogue AP, enter a brief description why the AP is being revoked. When you revoke an AP from the Campus AP whitelist, the Campus AP whitelist retains the information of the AP. To revoke an invalid or rogue AP and permanently remove it from the whitelist, delete that entry.

You can revoke an AP from the Campus AP whitelist using the WebUI or CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions..

Deleting an AP from the Campus AP Whitelist

Before deleting an AP from the Campus AP whitelist, verify that auto certificate provisioning is either enabled or disabled only for IP addresses that do not include the AP being deleted. If you enable automatic certificate provisioning for an AP that is still connected to the network, you cannot delete it from the Campus AP whitelist; the controller immediately re-certifies the AP and re-creates its whitelist entry.

You can delete an AP from the Campus AP whitelist using the WebUI or CLI Command-Line Interface.

Purging a Campus AP Whitelist

Before adding a new managed device to a network using CPsec Control Plane Security. CPsec is a secure form of communication between a controller and APs to protect the control plane communications. This is performed by means of using public-key self-signed certificates created by each master controller. , purge the campus AP Campus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on. whitelist on the new managed device. To purge a Campus AP whitelist, issue the following command:

Offloading a Controller Whitelist to ClearPass Policy Manager

This feature allows to externally maintain AP whitelist in a ClearPass Policy Manager server. The controller, if configured to use an external server, can send a RADIUS Remote Authentication Dial-In User Service. An Industry-standard network access protocol for remote authentication. It allows authentication, authorization, and accounting of remote users who want to access network resources.  access request to a ClearPass Policy Manager server. The MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the AP is used as a username and password to construct the access request packet. The ClearPass Policy Manager server validates the RADIUS Remote Authentication Dial-In User Service. An Industry-standard network access protocol for remote authentication. It allows authentication, authorization, and accounting of remote users who want to access network resources.  message and returns the relevant parameters for the authorized APs.

The following supported parameters are associated with the following Vendor Specific Attributes (VSAs). The ClearPass Policy Manager server sends them in the RADIUS Remote Authentication Dial-In User Service. An Industry-standard network access protocol for remote authentication. It allows authentication, authorization, and accounting of remote users who want to access network resources.  access accept packet for authorized APs:

ap-group: Aruba-AP-Group

ap-name: Aruba-Location-ID

ap-remote-ip: Aruba-AP-IP-Address

The following defaults are used when any of the supported parameters are not provided by the ClearPass Policy Manager server in the RADIUS Remote Authentication Dial-In User Service. An Industry-standard network access protocol for remote authentication. It allows authentication, authorization, and accounting of remote users who want to access network resources.  access accept response:

ap-group: The default ap-group is assigned to the AP.

ap-name: The MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the AP is used as the AP name.

There is no change in the Remote AP role assignment. The Remote AP is assigned the role that is configured in the VPN Virtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two. default-rap profile.

ArubaOS now provides support for ClearPass Policy Manager to whitelist Remote APs in a cluster environment. You can configure ClearPass Policy Manager as an external server that authenticates Remote APs using the MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of Remote APs. The Remote APs are authenticated by maintaining whitelist entries in ClearPass Policy Manager, and the cluster inner IP addresses are assigned on the Mobility Master. Hence, the inner IP address assignment is centralized and forwarded to the associated managed devices in the cluster.

Run the following commands to add this server group to the default-rap vpn profile:

Run the following command to configure the Remote AP inner IP pool on the Mobility Master for cluster deployment :

(host) [mynode] (config) #lc-rap-pool rap-cluster 3.1.1.3 3.1.1.10

Important Points to Remember

The lc-rap-pool command currently supports only IPv4 address in a cluster environment.

In the cluster environment, the managed device does not use the IP address received from ClearPass Policy Manager, and tries to obtain the cluster inner IP address from Remote AP inner IP pool for cluster deployment (lc-rap-pool) configured on the Mobility Master. If the managed device fails to obtain the inner IP address, the Remote AP does not establish IKE Internet Key Exchange. IKE is a key management protocol used with IPsec protocol to establish a secure communication channel. IKE provides additional feature, flexibility, and ease of configuration for IPsec standard./IPsec Internet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. tunnel with the managed device. The whitelist entries are automatically generated after successful authentication and IP assignment from the Remote AP inner IP pool.

When the Remote AP goes down on all cluster members, both the managed device and Mobility Master delete the Remote AP whitelist entries that are generated automatically.
