本次練習是參考Cisco網路學院
CCNA Exploration 4.0 LAN Switching and Wireless
Student Lab Manual
我將它轉成Dynamips的設定檔 並寫下自己的實驗紀錄
Dynamips的設定檔:

[[Router SW1]]
model = 3640
console = 2001
autostart = false
slot0 = NM-16ESW
F0/1 = SW2 F0/1
F0/2 = SW3 F0/1
F0/3 = PC4 F0/0
[[Router SW2]]

[[Router SW3]]
model = 3640

F0/2 = SW2 F0/2
[[Router PC1]]
model = 3640

slot0 = NM-1FE-TX
[[Router PC2]]

slot0 = NM-1FE-TX
[[Router PC4]]
model = 3640
console = 2007
autostart = false
slot0 = NM-1FE-TX
這Lab只是基本STP設定練習
我的設定是
1. 先設定PC1-4
hostname PC*
!
no ip domain lookup
!
interface FastEthernet0/0
ip address 172.17.10.2* 255.255.255.0
no shutdown
!
ip route 0.0.0.0 0.0.0.0 172.17.10.254
!
line con 0
logging synchronous
!
end
2. 設定Switch1-3的Trunk Port
Switch1-3:
interface range fastEthernet 0/1 - 2
switchport mode trunk
switchport trunk encapsulation dot1q
3. 設定Switch1-3的Management VLAN
Switch1-3:
interface vlan 1
ip address 172.17.10.* 255.255.255.0
no shutdown
互ping 有通
4. Switch1-3 觀察目前STP的參數
Switch1-3:
show spanning-tree
debug spanning-tree events
5. Switch1手動關閉 Fa0/1
SW1(config)#interface fastEthernet 0/1
SW1(config-if)#shut
然後再觀察SW2-3的Log的變化
SW3#
*Mar 1 00:27:39.451: STP: VLAN1 Fa0/2 -> listening
*Mar 1 00:27:40.419: STP: VLAN1 heard root 32768-cc01.0c93.0000 on Fa0/2
*Mar 1 00:27:40.423: current Root has 32768-cc00.0c93.0000
*Mar 1 00:27:40.431: STP: VLAN1 Topology Change rcvd on Fa0/2
*Mar 1 00:27:40.431: STP: VLAN1 sent Topology Change Notice on Fa0/1
SW3#
*Mar 1 00:27:54.451: STP: VLAN1 Fa0/2 -> learning
SW3#
*Mar 1 00:28:09.455: STP: VLAN1 sent Topology Change Notice on Fa0/1
*Mar 1 00:28:09.455: STP: VLAN1 Fa0/2 -> forwarding
SW3#
8. 驗證指令
show spanning-tree
debug spanning-tree events
最後PC1-4,SW1-3互ping 有通 結束
