Intra BSS traffic is traffic between wireless stations in the same BSS. When Intra BSS is enabled, wireless stations can communicate with each other. When Intra BSS is disabled, wireless stations cannot communicate with each other. You can enable or disable Intra BSS communication using the CI command in SMT menu 24.8.
