Spanning Tree Protocol (STP), defined in IEEE 802.1D, builds a loop-free logical topology for LANs. It blocks redundant links between any two network devices and leaves a single active link between them so as to eliminate loops. If an active link fails, STP immediately selects a proper red...
Spanning Tree Protocol (STP) is a widely used and effective method for preventing loops in a network. It helps prevent loops by actively monitoring thenetwork topologyand selectively blocking redundant links. This ensures that there is only one active path between any two network devices. By doing...
Spanning Tree Protocol (STP) is a Layer 2 network protocol used to prevent looping within a network topology. STP was created to avoid the problems that arise when computers exchange data on a local area network (LAN) that contains redundant paths. If the flow of traffic is not carefully mo...
解析:Explanation:STP’s main task is to stop network loops from occurring on your Layer 2 network (bridges or switches). It vigilantly monitors the network to find all links, making sure that no loops occur by shutting down any redundant ones. STP uses the spanning-tree algorithm (STA) to...
When a spanning tree protocol is deployed on devices on a network, the devices exchange Bridge Protocol Data Units (BPDUs) to calculate a loop-free network topology. The devices continuously update and exchange BPDUs to determine the ports to be blocked and those to become root ports. Port ...
MSTP is compatible with RSTP and STP, and RSTP is compatible with STP. Table 29-1 compares the three spanning tree protocols. Table 29-1 Comparison of three spanning tree protocols Spanning Tree Protocol Characteristics Application Scenario STP Supports only single instances. Forms a ...
To prevent loops from causing broadcast storms and making the MAC address table unstable, the Spanning Tree Protocol (STP) runs switches when redundant links are used on the network. STP is a basic feature of datacom products including switches, routers, and WLAN products. This chapter describes...

Every Bridge (Switch) Participating in aSpanning Tree Protocolnetwork is assigned with a numerical value called Bridge Priority (Switch Priority) Value. Bridge Priority (Switch Priority) Value is a 16-bit binary number. By default, all Cisco Switches has a Bridge Priority (S...
