R16(config)# do show span vlan 1

VLAN1 is executing the ieee compatible Spanning Tree protocol
  Bridge Identifier has priority 32768, address cc12.2884.0000
  Configured hello time 2, max age 20, forward delay 15
  We are the root of the spanning tree
  Topology change flag not set, detected flag not set
  Number of topology changes 1 last change occurred 00:03:15 ago
          from FastEthernet0/2
  Times:  hold 1, topology change 35, notification 2
          hello 2, max age 20, forward delay 15
  Timers: hello 0, topology change 0, notification 0, aging 300

Port 3 (FastEthernet0/2) of VLAN1 is forwarding
   Port path cost 19, Port priority 128, Port Identifier 128.3.
   Designated root has priority 32768, address cc12.2884.0000
   Designated bridge has priority 32768, address cc12.2884.0000
   Designated port id is 128.3, designated path cost 0
   Timers: message age 0, forward delay 0, hold 0
   Number of transitions to forwarding state: 1

这个显示方式不一样啊？


这条命令也没有了 R16(config)#spanning-tree mode
不能选择生成树了！ 并且有事开机的时候设备的接口全是关闭的。包括VLAN 1

Reapeyron

gns3模拟交换机功能不全，很多命令敲不进去，而且有些显示的内容也不太一样。建议用iou
