What Does Spanning Tree Protocol (STP) Do? TheSpanning Tree Protocol (STP)avoids the formation of loops orbroadcast storms. It does so by blocking ports where it senses loop formation. In other words, the STP looks after the network to make it loop-free by tracking all the links and stop...
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...
In this lesson, we'll discuss the properties of a spanning tree. We will define what a spanning tree is and how they can be used to solve problems...
VLANs are used to segment a LAN into multiple collision domains, but the STP process alone does not do this.E. Routers are used to prevent routing loops at layer 3 of the OSI model. STP operates at layer 2.反馈 收藏
show spanning-tree 2. Root Port Selection. Every non-root bridge determines the most efficient path to reach the root bridge. The port providing the shortest path becomes the designated root port for that non-root bridge. Each non-root bridge has only one root port, which offers the quickest...
and finds the calculated configuration BPDU inferior to the original configuration BPDU {0, 0, 0, Port A2} on port C1. DeviceC then blocks port C1 and does not update its configuration BPDU. In this manner, Port C1 no longer forwards data until spanning tree recalculation is triggered, for...
What is STP and how does it work? 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 th...
What is the reason for running spanning-tree in a Cisco Single-Site Secure Network Foundation Solution?() A. To protect the network in case someone inadvertently creates a physical loop in it B. To ensure that if a ...

当输入命令'spanning - tree loopguard default'时，其作用是将环回保护（loop guard）的状态从默认的禁用（disabled）更改为启用（enabled），所以B选项正确。
