基于时间ACL
Router(config)#time-range freetime
Router(config-time-range)#absolute start 8:00 1 jan 2006 end 18:00 30 dec 2010 
Router(config-time-range)#periodic daily 0:00 to 9:00 
Router(config-time-range)#periodic daily 17:00 to 23:59
Router(config)#access-list 100 permit ip any host 160.16.1.1
Router(config)#access-list 100 permit ip any any time-range freetime
Router(config)#interface fastethernet 1/0
Router(config-if)#ip access-group 100 in  

NAT
int f0/0
ip nat inside
int s1/0
ip nat outside
access-list 1 permit any 
ip nat pool poolname 192.168.2.2  192.168.2.2 netmask 255.255.255.0
ip nat [inside|outside] source list 1 pool poolname 
int s1/0
ip access-group 1 [out|in] 

MSTP
S2126-A (config)#spanning-tree   ！开启生成树 
S2126-A (config)#spanning-tree mode mstp    ！配置生成树模式为MSTP 
S2126-A(config)#spanning-tree mst configuration    ! 进入MSTP配置模式
S2126-A(config-mst)#instance 1 vlan 1,10    ！配置instance 1（实例1）并关联Vlan 1和10
S2126-A(config-mst)#instance 2 vlan 20,40     ！配置实例2并关联Vlan 20和40
S2126-A(config-mst)#name region1            ！配置域名称
S2126-A(config-mst)#revision 1               ！配置版本（修订号）

S3550-A (config)#spanning-tree mst 1 priority 4096   ！配置交换机S3550-A在instance 1
S3550-B (config)#spanning-tree mst 2 priority 4096   ！配置交换机S3550-A在instance 1

RSTP
SwitchA(config)# spanning-tree   ！打开生成树
SwitchA(config)# spanning-tree mode rstp   ! 采用生成树RSTP模式
SwitchA(config)# spanning-tree hello-time 4   ! 配置交换机发送BPDU报文的时间间隔为4s（秒），
                                        缺省为2s，范围是1—10s 。若要恢复到缺省值，用命令no spanning-tree hello-time
SwitchA(config)# spanning-tree forward-time 30   ! 配置进入转发状态的时间为20s，缺省为15s，范围是4—30s
SwitchA(config)# spanning-tree max-age 40     !配置BPDU报文的有效存活时间为40s，缺省为20s，范围是6—40s
