Differences between Intra-BSS Traffic Blocking and Layer-2 Isolation

The primary difference between Intra-BSS Traffic Blocking and Layer-2 isolation lies in their scope and functionality:

• Scope:
  • Intra-BSS Traffic Blocking applies specifically to wireless networks and wireless clients connected to the same access point or extender.
  • Layer-2 Isolation, on the other hand, is a feature found in wired networks, typically applied to devices connected to the same switch or wired segment.
• Functionality:
  • Intra-BSS Traffic Blocking prevents wireless clients from directly communicating with each other, ensuring that traffic flows through the router or gateway.
  • Layer-2 Isolation prevents communication between devices within the same Layer-2 domain, such as devices connected to the same switch, but allows communication with devices in different Layer-2 domains.
• Applicability:
  • Intra-BSS Traffic Blocking is relevant for wireless networks to enhance security and optimize bandwidth usage between wireless clients.
  • Layer-2 Isolation is used in wired networks to improve security and segmentation of devices within the same local area network (LAN).

Both Intra-BSS Traffic Blocking and Layer-2 Isolation are valuable features that help bolster network security and performance. Depending on your specific network requirements, you can enable these features to maintain a secure and efficient networking environment.
