plaintext Switch# configure terminal Switch(config)# spanning-tree portfast bpduguard default 在这个示例中,用户首先进入交换机的全局配置模式(configure terminal),然后输入 spanning-tree portfast bpduguard default 命令来配置 PortFast 和 BPDUGuard 的默认行为。 请注意,具体的配置命令和语法可能会因不同厂商和...
作用:通过检测非法的BPDU,保护交换机不受未经授权的设备干扰。 配置BPDU Filter • 进入接口配置模式:interface • 启用BPDU Filter功能:spanning-tree bpdufilter enable 作用:通过过滤传入或传出的BPDU,防止异常BPDU影响网络稳定性。 配置VTP • 进入全局配置模式:config terminal • 启用VTP功能:vtp mode •...
如果交换机从一个接口接收到优先级高的BPDU,会把该BPDU保存下来并且该接口不再往外发送BPDU; 在收敛时只有根桥产生BPDU,其余交换机只能从RP接收BPDU后才从DP发送出去;这样非根桥可能从DP或者NDP接受到BPDU; 如果交换机从DP接收到优先级低的BDPU会丢弃,并给源MAC发送自己较新的BPDU;如果从NDP收到优先级低的BPDU...

Bpdus are sent between bridges, which allow them to learn about the network. ■ Port costs are inversely proportional to the port bandwidth. The higher the bandwidth, the lower the port cost. ■ Designated ports have the lowest root Path Cost. This is the best path to the root. ■ Ports...

If the whole-switch parameter Force-Version is set to "stp-compatible", the mcheck setting is ignored and STP BPDUs are sent out all ports. Disable this feature on all ports that are known to be connected to devices that are running 802.1D STP. Use the "no" option on the spanning ...
在整个交换网络泛洪就形成了广播风暴。BPDU (Bridege Protocol Data Unit )STP 的各种选举是通过交换BPDU报文来实现的。BPDU是直接封装在以太网帧中。对于参与STP的所有SW,他们都是通过数据消息的交换来获取网络中的其他SW信息, 交换机 监控 接口 以太网
