Part1.Smartports宏
Smartports宏是预先订制的配置脚本,可用于绝大多数的Cisco交换机上。通过使用这些脚本,不仅可以建立更稳定的端口配置,甚至可能防止未来出现问题。默认状态下,Cisco交换机提供的宏覆盖了下述这些种类的设备: Cisco-desktop,Cisco-phone,Cisco-switch,Cisco-router和Cisco-wireless。每个宏对应的命令如下:
1)针对终端PC的宏cisco-desktop
switchport mode access
switchport port-security
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
macro de.ion cisco-desktop
spanning-tree portfast
spanning-tree bpduguard enable
2)针对SW的宏cisco-switch
switchport trunk encapsulation dot1q
switchport mode trunk
macro de.ion cisco-switch
auto qos voip trust
spanning-tree link-type point-to-point
3)针对Router的宏cisco-router
switchport trunk encapsulation dot1q
switchport mode trunk
mls qos trust dscp
macro de.ion cisco-router
auto qos voip trust
spanning-tree portfast trunk
spanning-tree bpduguard enable
4)针对IP Phone的宏cisco-phone
switchport mode access
switchport voice vlan 1
switchport port-security
switchport port-security maximum 3
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
macro de.ion cisco-phone
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
5)针对无线AP的宏cisco-wireless
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
mls qos trust cos
macro de.ion cisco-wireless
auto qos voip trust
spanning-tree bpduguard enable
启用Smartports的方式:
Switch(config)# int fa0/19
Switch(config-if)# macro apply cisco-desktop $access_vlan 1 //需要定义这个端口成为哪个VLAN的一部分
Switch(config-if)#show parser macro //这个命令会显示每个宏所作的工作
当然,我们也可以自己定义一个宏:
Switch(config)# macro name steven
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable
switchport port-security maximum 1 //定义可以连接的设备的数量上限
switchport access vlan 1 //将该端口归入vlan1
@ //通过@符号结束宏
Switch(config)# interface gigabitethernet1/0/2 //接口下启用宏
Switch(config-if)# macro apply steven

Part3.Vlan配置
Switch(config)#vlan vlan-id & Switch(config)#name vlan-name //创建Vlan Method1
