如果网络中没有其他交换机的优先级设置得比0更低,那么该交换机将成为VLAN 1的根桥。这可能会影响网络的流量路径和冗余链路的利用方式,因为所有非根桥交换机都会根据到根桥的最短路径来选择转发端口。 4. 配置指南 要在交换机上配置spanning-tree vlan 1 priority 0,你需要进入交换机的全局配置模式,然后输入以下...

(1)在cisco3750上新建vlan420,把fa1/0/3和1/0/4都加到420里,交换机上的3口亮绿灯,但4口却一直亮橘×××灯,也就是常见的spanning-tree转发等待时一样的颜色,用show spanning-tree命令一看,出现下面提示: VLAN0420 Spanning tree enabled protocol ieee Root ID Priority 33188 Address 0014.6afd.ab80 This ...

• 配置优先级:spanning-tree priority • 配置根保护:spanning-tree guard root 作用:通过防止网络出现环路,提高网络可靠性和稳定性。 配置Port Security • 进入接口配置模式:interface • 启用端口安全功能:switchport port-security • 配置最大允许MAC地址:switchport port-security maximum <max_number> ...
spanning-tree priority 0 on Aspanning-tree priority 8 on BSo I have the attached forwarding/blocking status when I do "show spanning-tree".It's a very hasty sketch but does it look as you would expect?Thanks very much. 365415.png 22 KB 0 Kudos Richard Brodie_1 Honored ...
@优先级,priority(4096的倍数)默认为32768(越小越优) 如果要进行修改的话必须为4096的倍数修改,随意输入数字是不可以的 @如果优先级相同的话,比较MAC地址,(越小越优)但这里会存在一个问题 因为MAC地址是全球唯一的,不存在重复,而生产厂家生产设备的时候所有的MAC地址也是从小到大进行排列的,越早生产的设备MAC越...
spanning-tree vlan 1-4094 priority 0 Just in case you want to proceed with the debugs as well, the debugs will indeed be visible in the show logging command on the Catalyst - but I recommend configuring the buffer for the logs to be bigger and to store all messages including the debug...
