What does Spanning Tree Protocol (STP) do? - Server Fault
May 14, 2009 · The Spanning Tree Protocol (STP), is defined in the IEEE Standard 802.1D. As the name suggests, it creates a spanning tree within a mesh network of connected layer-2 bridges (typically Ethernet switches), and disables those links that are not part of the tree, leaving a single active path between any two network nodes. STP short summary:
What benefits are there to enabling STP on a WiFi access point?
In most deployments it is not necessary to configure STP on an access point. However, there are several deployment scenarios where it is advisable. One such scenario I encountered in production when it was biting the network in the proverbial posterior.

My next question pertains to the powerconnect STP port settings. Majority of the ports on ESW1-3 are strictly server nodes and not additional network endpoints. Would it be better to: disable STP for the ports connected to servers, leaving enabled for network appliances connected to the switch(e.g. additional routers/smaller switches)

Dec 14, 2023 · If STP is enabled, and every port is on the same vLAN, all but one link connecting the two switches will be disabled to prevent forwarding loops. If that port loses link, another pair will be enabled (if the intent is high redundancy).

Feb 16, 2021 · What the dropped packets mean is that no kernel subsystem has registered STP as a supported protocol; the ethernet driver doesn't know where to send the packet, so drops it and increments the dropped counter. This is itself fine, but …

Jan 29, 2022 · Shared-media links use the more universal rule from the IEEE 802.1Q quote above: if any STP bridge on that collision domain chooses the port in question as its root path, the local port becomes designated.
What variant of STP is implemented in the Linux kernel?
Apr 21, 2020 · A single instance of STP runs for all the VLANs. This is interoperable with MSTP: conceptually, it's as if we were running MSTP with all VLANs mapped to a single MST instance. So, to answer question 1, Linux does not do MSTP, but STP + VLAN-aware bridge is interoperable with MSTP. EDIT: You might wonder how Cumulus does PVST+.

The beauty of STP is that in the vast majority if cases, it looks after itself - by tinkering with the default, tried and tested defaults, you're risking making things worse for your event -- and may impact on your end users for the relatively short time they're using your network.
