将coresw1配置优先级,vlan 20 priority 4096(次优的) 将coresw2配置优先级,vlan 10 priority 4096(次优的) 这样,BLK端口就会出现在接入层,也正是我们想要的了, 具体的配置思路如下: 1确保所有接口trunk //由于是承载着多个VLAN,所以trunk是必须的 2所有交换机上配置相同的VLAN //为了实现链路的切换,所以VLAN...

BID的组成:2(Bridge Priority优先级)+6(MAC)=8 Bytes 默认Priority:32768(0x8000)可以从0到65535 2950以上的交换机会在这个值上再加上VLAN号,因为CISCO默认启用PVST(一个VLAN是一个生成树) 每个交换机都有一个基准的MAC地址,用下面的命令可以看到
