M4300 Series and M4300-96X Fully Managed Switches Spanning Tree Protocol Concepts The purpose of the Spanning Tree Protocol (STP) is to eliminate loops in the switch system. There are three STPs: Classic STP (802.1d), Rapid STP (RSTP, 802.1w), and Multiple STP (MSTP, 802.1s). While STP can take 30 to 50 seconds to respond to a topology change, RSTP is typically able to respond to changes within a few seconds. RSTP can revert back to 802.1d in order to interoperate with legacy bridges on a per-port basis. This drops the benefits it introduces. In Multiple Spanning Tree Protocol (MSTP), each Spanning Tree instance can contain several VLANs. Each Spanning Tree instance is independent of other instances. This approach provides multiple forwarding paths for data traffic, enabling load balancing, and reducing the number of Spanning Tree instances required to support a large number of VLANs. Configure Classic STP (802.1d) The example is shown as CLI commands and as a local browser interface procedure. CLI: Configure Classic STP (802.1d) (Netgear Switch) (Config)# spanning-tree (Netgear Switch) (Config)# spanning-tree mode stp (Netgear switch) (Interface 1/0/3)# spanning-tree port mode Local Browser Interface: Configure Classic STP (802.1d) 1. Enable 802.1d on the switch. a. Select Switching > STP > STP Configuration. A screen similar to the following displays. STP 522 Software Administration Manual
