on my firewall to trunk interfaces and no luck. Ok after I applied a spanning tree bpdufilter on the port, its working now. "tony" <> wrote in message
1、模拟器与真机还是有区别的 2、spanning-tree 后面需要接模式 也就是说你要指定生成树的模式 是快速生成树还是实例生成树 这个是需要指定的,不然就会报错 3、别人的命令不要盲目遵从 要理解为什么要启用这个命令 4、
Spanning-Tree Protocol (STP) prevents loops from being formed when switches or bridges are interconnected via multiple paths. Spanning-Tree Protocol implements the 802.1D IEEE algorithm by exchanging BPDU messages with other switches to detect loops, and then removes the loop Read more Sub-...
spanning-tree mode pvst就是启用基于VLAN的生成树模式,这是思科的独有用法,简单说就是一个VLAN一棵树,在一个网络里,不同的VLAN可以有不同的根桥,不同的阻塞端口等等,其主要目的是为了提高链路利用率(可以想象,如果所有VLAN都是同一棵树,必定有一部分线路处于完全的block状态)spanning-tree extend system-id启用...

Spanning Tree Protocol (STP)—Checks logical port-state consistency, either port or VLAN. Consistency is checked against STP and PIXM components. Note Currently, consistency is checked only against the STP internal database based on the software port state and from ...
Spanning Tree Algorithm: Introduction (3.1.2.1) Redundancy increases the availability of the network topology by protecting the network from a single point of failure, such as a failed network cable or switch. When physical redundancy is introduced into a design, loops and duplicate frames occur. ...
