Cisco Context Aware Services provide real-time tracking of mobile assets and users by gathering contextual information from networked devices. This service is not limited to wireless devices; it can track both wired and wireless devices within the network. The technology utilizes elements like Received Signal Strength Indicator (RSSI) and Time Difference of Arrival (TDoA) for location tracking and telemetry. References:

LDAP (Lightweight Directory Access Protocol) is a protocol used for accessing and maintaining distributed directory information services over an IP network. In the context of Cisco ISE (Identity Services Engine), LDAP can be utilized as a directory service to authenticate and authorize users during local web authentication processes. LDAP supports a wide range of directory services, including Microsoft Active Directory, which is commonly used in enterprise environments.

When implementing Cisco Identity-Based Networking on a Cisco AireOS controller with two ACLs where one is applied directly on the WLC interface and another referenced by ISE for a specific group policy, the resulting ACL for a user in that group would be a combination of both ACLs. The BASE_ACL applied on the corporate_clients interface acts as the default ACL for all corporate clients, while HR_ACL is specific for Human Resources users. When a Human Resources user connects, HR_ACL takes precedence but does not replace BASE_ACL; instead, it appends its rules to those of BASE_ACL resulting in an aggregated set of rules from both ACLs.

To ensure that only PEAP authentication is used for network access through a wireless network using WPA2 Enterprise with 802.1X, enabling AAA override on an SSID allows individual client authentication requests to be modified by RADIUS server responses dynamically. By configuring an access policy in Cisco Identity Services Engine (ISE) that permits access solely when PEAP is used as the EAP authentication method, any user attempting to authenticate using EAP-FAST will be denied network access until their devices are configured correctly for PEAP usage.
