spanning-tree loopguard default 命令用于在交换机上全局启用 Loop Guard 特性。Loop Guard 是一种生成树协议(STP)的增强特性,用于防止因单向链路故障导致的网络环路。 工作原理: Loop Guard 的工作原理是在 STP 的阻塞端口(Blocked Port)上启用额外的检查。当这些端口在最大老化时间(Max Age
BPDU Guard特性可以全局启用也可以基于基于接口的启用,两种方法稍有不同.当在启用了Port Fast特性的端口收到了BPDU后,BPDU Guard特性将关闭(err-disable)该端口(正常情况是启用了Port Fast特性的端口不可能收到BPDU). 配置方法: Switch(config)# spanning-tree portfast bpduguard default /---在启用了Port Fast特...
全局打开loop guard特性,启用loop guard功能,能防止根端口或备份口因收不到bpdu而产生的可能的环路。这个是锐捷交换机上MSTP生成树防环的命令,只要参加了生成树选举的交换机都需要配置。

()The command changes the status of loop guard from the default of disabled to enabled.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。
The loop guard engine monitors the receipt of bridge protocol data units (BPDUs) by the ports. If a given port stops receiving BPDUs, the loop guard engine prevents the spanning tree protocol engine from transitioning the given port to the forwarding state. Instead, the loop guard engine ...

### 步骤1:在Kubernetes集群中找到需要配置spanning-tree guard loop的节点 在Kubernetes集群中,我们需要找到需要配置spanning-tree guard loop的节点。这些节点通常是网络设备或者主机节点。可以使用以下命令在Kubernetes集群中列出所有节点: ```bash kubectl get nodes ...
