Loop Protection with Instant 8.4.x

Aruba Instant APs (IAP) provide an effective way to connect to multiple LAN segments for branch offices/sites with APs that have multiple Ethernet ports like AP303H, AP205H, AP303

Instant 8.4.x introduced the loop protection feature that detects and avoids the formation of loops on the Ethernet ports of an Instant AP. The loop protect feature can be enabled on all IAPs, particularly those that have multiple Ethernet ports.


Along with Loop protect, we also have storm-control feature in which it will restrict broadcast packets per sec.

In this short guide (12 pages), we’ll use loop protection in three common scenarios.

  1. IAP Down Link Loop Scenario
  2. IAP Switch Port Loop Scenario.
  3. IAP WAN Loop Scenario
