Loop protection increases the efficiency of STP, RSTP, and MSTP by preventing ports from moving into a forwarding state that would result in a loop opening up in the network. Spanning-tree protocol loop protection enhances the normal checks that spanning-tree protocols perform on …

Spanning Tree Protocol (STP) and its advanced version, Rapid Spanning Tree Protocol (RSTP), help create a loop-free logical network topology. They do this by blocking redundant paths based on factors like link speed and switch priority. Here’s how to implement and configure STP in UniFi: Enable RSTP: UniFi switches enable RSTP by default.

执行命令stp loop-protection，配置交换设备根端口或Alternate端口的环路保护功能。 缺省情况下，端口的环路保护功能处于关闭状态。

2024年2月29日 · 执行命令stp loop-protection，配置交换设备根端口或Alternate端口的环路保护功能。 缺省情况下，端口的环路保护功能处于关闭状态。

2022年3月31日 · RSTP定义了两种全新的端口角色：Backup Port（备份端口）和Alternate Port（预备端口）。 Backup Port（备份端口）：Backup Port就是由于学习到自己发送的配置BPDU报文而阻塞的端口，为指定端口的备份，提供了另外一条从根节点到叶节点的备份通路。 Alternate Port（预备端口）：Alternate Port就是由于学习到其它网桥发送的配置BPDU报文而阻塞的端口，提供了从指定桥到根的另一条可切换路径，作为根端口的备份端口。 RSTP将原来 …

Run the stp loop-protection command to enable loop protection on the root port or alternate port. By default, loop protection is disabled on a port. The following example shows how to configure loop protection on GigabitEthernet0/0/4 and check whether the configuration is successful.

As the diagram shows, there are a total of 24 switches present on the same subnet and participating in the same RSTP. The core switches are HPE 1920s and field devices are MOXA L2 switches. My questions are these. Is this a good design? Can/Should RSTP timers be changed from defaults and if so should it be done on non-root bridges

2024年6月30日 · Each switch should have a direct run down to the distribution switch (es). The normal way is to use fiber for the vertical cable between data closets, and use copper for the horizontal cable out to the workstations. Lines and loops should not be used, trees are what you should use. Has any answer solved your question?

2024年8月1日 · To effectively compare STP, RSTP, and the integration of Loop Guard, it’s vital to understand each element's contribution to network stability and efficiency. While STP laid the groundwork for loop-free network designs, its slower convergence and handling of topology changes could not meet the demands of modern network requirements.

2 天之前 · 1. RSTP环路保护功能概述 RSTP（Rapid Spanning Tree Protocol）环路保护功能是网络中一种重要的保护机制。它通过检测端口是否长时间收不到上游设备的BPDU（Bridge Protocol Data Unit）来判断链路是否出现故障。一旦检测到链路故障，环路保护功能会将根端口或Alternate端口切换到Discarding状态，避免网络中形成 ...
