STP配置实验

实验步骤按照顺序来 1.SWA配置 SWA#conf t SWA(config)#int rang f0/1 - 2 SWA(config-if-range)#switchport mode trunk SWA(config-if-range)#channel-group 1 mode on SWA(config-if-range)#exit SWA(config)#int range f0/14 - 15 SWA(config-if-range)#switchport mode trunk SWA(config-if-range)#end SWA#vlan database SWA(vlan)#vlan 2 SWA(vlan)#vlan 3 SWA(vlan)#vlan 4 SWA(vlan)#vtp server SWA(vlan)#vtp domain sy SWA(vlan)#vtp password cisco SWA(vlan)#vtp pruning SWA(vlan)#exit 2.SWB配置 SWB#conf t SWB(config)#int range f0/1 - 2 SWB(config-if-range)#switchport mode trunk SWB(config-if-range)#channel-group 1 mode on SWB(config-if-range)#exit SWB(config)#int range f0/14 - 15 SWB(config-if-range)#switchport mode trunk SWB(config-if-range)#end SWB#vlan database SWB(vlan)#vtp server SWB(vlan)#vtp domain sy SWB(vlan)#vtp password cisco SWB(vlan)#exit 3.SWC配置 SWC#conf t SWC(config)#int range f0/14 - 15 SWC(config-if-range)#switchport mode trunk SWC(config-if-range)#end SWC#vlan database SWC(vlan)#vtp client SWC(vlan)#vtp domain sy SWC(vlan)#vtp password cisco SWC(vlan)#exit SWC#show spanning-tree Port 15 (FastEthernet0/14) of VLAN1 is forwarding Port 16 (FastEthernet0/15) of VLAN1 is blocking Port 15 (FastEthernet0/14) of VLAN2 is forwarding Port 16 (FastEthernet0/15) of VLAN2 is blocking Port 15 (FastEthernet0/14) of VLAN3 is blocking Port 16 (FastEthernet0/15) of VLAN3 is forwarding Port 15 (FastEthernet0/14) of VLAN4 is blocking Port 16 (FastEthernet0/15) of VLAN4 is forwarding 4.SWD配置 SWD#conf t SWD(config)#int range f0/14 - 15 SWD(config-if-range)#switchport mode trunk SWD(config-if-range)#end SWD#vlan database SWD(vlan)#vtp client SWD(vlan)#vtp domain sy SWD(vlan)#vtp password cisco SWD(vlan)#exit SWD#show vtp status VTP Version                     : 2 Configuration Revision          : 2 Maximum VLANs supported locally : 256 Number of existing VLANs        : 9 VTP Operating Mode              : Client VTP Domain Name                 : sy VTP Pruning Mode                : Enabled VTP V2 Mode                     : Disabled VTP Traps Generation            : Disabled MD5 digest                      : 0xF8 0xB6 0x3B 0x3A 0xF4 0xBF 0xD9 0x1E Configuration last modified by 0.0.0.0 at 3-1-02 00:20:36 SWD#show vlan-sw brief VLAN Name                             Status    Ports ---- -------------------------------- --------- ------------------------------- 1    default                          active    Fa0/0, Fa0/1, Fa0/2, Fa0/3                                                 Fa0/4, Fa0/5, Fa0/6, Fa0/7                                                 Fa0/8, Fa0/9, Fa0/10, Fa0/11                                                 Fa0/12, Fa0/13 2    VLAN0002                         active    3    VLAN0003                         active    4    VLAN0004                         active        1002 fddi-default                     active    1003 token-ring-default               active    1004 fddinet-default                  active    1005 trnet-default                    active SWD#conf t SWD(config)#int f0/2 SWD(config-if)#switchport access vlan 2 SWD(config-if)#end SWD#conf t SWD(config)#spanning-tree uplinkfast SWD(config)#int  range f0/1 - 13 SWD(config-if-range)#spanning-tree portfast SWD(config-if-range)#end SWD#show spanning-tree summary    UplinkFast is enabled SWD#show spanning-tree interface f0/2    The port is in the portfast mode SWD#show spanning-tree Port 15 (FastEthernet0/14) of VLAN1 is blocking Port 16 (FastEthernet0/15) of VLAN1 is forwarding Port 15 (FastEthernet0/14) of VLAN2 is blocking Port 16 (FastEthernet0/15) of VLAN2 is forwarding Port 15 (FastEthernet0/14) of VLAN3 is forwarding Port 16 (FastEthernet0/15) of VLAN3 is blocking Port 15 (FastEthernet0/14) of VLAN4 is forwarding Port 16 (FastEthernet0/15) of VLAN4 is blocking 5.SWC配置 SWC#conf t SWC(config)#int f0/2 SWC(config-if)#switchport access vlan 2 SWC(config-if)#end SWC#conf t SWC(config)#spanning-tree uplinkfast  SWC(config)#int range f0/1 - 13 SWC(config-if-range)#spanning-tree portfast SWC#show spanning-tree summary    UplinkFast is enabled SWC#show spanning-tree interface fastEthernet 0/2    The port is in the portfast mode 6.SWB配置 SWB#conf t SWB(config)#spanning-tree vlan 3 root primary SWB(config)#spanning-tree vlan 4 root primary SWB(config)#end SWB#show spanning-tree summary Root bridge for: VLAN3, VLAN4. 7.SWA配置 SWA#conf t SWA(config)#spanning-tree vlan 2 root primary SWA(config)#spanning-tree vlan 1 root primary SWA(config)#end SWA#show spanning-tree summary Root bridge for: VLAN1, VLAN2. 8.客户机配置 HostA(VLAN2): IP:192.168.1.2/24 HostB(VLAN2): ip:192.168.1.3/24 9.测试: HostA#ping 192.168.1.3 Type escape sequence to abort.
