Wireless Access

Hello, recently after updating our switches(3.3.2.0), we have seen issues with looping and the switches going on & offline. We currently have a switch stack setup, with 2x 1960 40p switches and 1x 1960 20p switch. Would disabling/filtering spanning tree on the bridge ports help with these connection issues? Also, are there any other recommended settings for the switches to change when seeing loop/disconnection issues? I found through research that there's an energy efficient ethernet option that can be toggled off, but I've had difficulty finding this setting. Thanks!

You may have more luck on the InstantON community. That 1960 switch is an InstantON product.

In general, if you have loops in your network, those may be deliberate for redundancy or unintentional. Spanning tree protects against loops in your network and getting broadcast storms where broadcast traffic is looping around. Generic advice would be to find where the loop is and address that issue. What sometimes happens due to misconfiguration is a portchannel (multiple physical cables forming one logical connection) where on one side the portchannel is not configured and traffic loops back through the other link in the port channel, or where redundant links are available but portchannel is not configured. How to configure that on Instant ON could better be asked on their forums.
