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
注意,Root Guard和Loop Guard特性不可同时使用,也不要在启用了Uplink Fast特性的端口上启用该特性.该特性一旦配置后,对所有VLAN都生效. 另外,也可以使用Loop Guard技术替代端口(AP)或RP由于单向链路的故障问题成为指定端口(DP): 如上图,交换机A做为根桥,由于交换机B和C之间发生单向链路故障,C将不能从B那里接...
The loop guard engine monitors the receipt of configuration bridge protocol data unit (BPDU) messages by the ports. If a given port stops receiving BPDU messages, the loop guard engine prevents the STP engine from transitioning the given port to the forwarding state. Instead, the loop guard ...

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。

Thus, to run the above mentioned setup without any spanning tree issues, or without the loopguard dafault affecting the setup, what would be the best possible solution to this, any ideas? One idea I thought is to disable spanning tree on the ports towards the operator routers. Please let ...
