Depending on the country of operation, the service providers (SPs) are required to support LI in their respective networks. In the United States, SPs are required to ensure LI compliance based on Communications Assistance for Law Enforcement Act (CALEA) specifications. Instant supports CALEA integration in a hierarchical and flat topology, mesh W-IAP network, the wired and wireless networks. Enable this feature only if lawful interception is authorized by a law enforcement agency. CALEA Server Integration To support CALEA integration and ensure LI compliance, you can configure the W-IAPs to replicate a specific or selected client traffic and send it to a remote CALEA server. Traffic Flow from W-IAP to CALEA Server You can configure a W-IAP to send GRE-encapsulated packets to the CALEA server and replicate client traffic within the GRE tunnel. Each W-IAP sends GRE encapsulated packets only for its associated or connected clients. The following figure illustrates the traffic flow from the W-IAP to the CALEA server. 298 | Services Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide
