Improve RF Resiliency by Swapping APs Between Switches in the Stack

This insight recommends changes to AP-Stacked Switch topology to improve the resiliency in Wi-Fi coverage when switches are down. In AP-Stacked Switch topology, if one of the member switches is down, all the neighboring APs connected to that particular switch cannot provide Wi-Fi coverage, implying a bad topology in the network. In such an event of Stacked Switch failures, Wi-Fi coverage can be improved by distributing the APs across the switches in the stack and by minimizing the number of neighboring APs connected to the same member switch. This insight recommends to swap the access points between the two members of stacked switches, provides the port number on each switch which needs to be swapped.

3. In the insights page you can view the following details:

   • Topology Improvements Summary—You can view the following information:

     • Improvement in Topology—The graph displays the current resilience and projected resilience after the AP swap.

     • Distribution of Swaps—The pie chart lists the number of access points that can be swapped to improve the Wi-Fi coverage.

     Click the View Floorplan button to view the resilient access points to switch topology on the Floorplan. Transfer the highlighted access points to the recommended switches to achieve this topology.

   • Resilience Trend—The chart displays the resilience percentage against the AP swap sequence. You can also hover over the graph to view the resilience percentage after the swap.

     The table at the bottom displays the switches and port details. You can view the following information:

     • Swap Sequence—Recommended order in which you should swap the ports.

     • Stack—Displays the switch stack. Click on the switch to navigate to the device details page.

     • Access Point Swaps across Switches—Detailed information of the swap with AP name and port number.

     • Improvement—This signifies the proportion of the site that would gain resilient coverage when a swap is made.
