Part1.Smartports宏 ? Smartports宏是預先訂制的配置腳本，可用于絕大多數(shù)的Cisco交換機上。通過使用這些腳本，不僅可以建立更穩(wěn)定的端口配置，甚至可能防止未來出現(xiàn)問題。默認狀態(tài)下，Cisco交換機提供的宏覆蓋了下述這些種類的設備： Cisco-desktop，Cisco-phone，Cisco-switch，Cisco-router和Cisco-wireless。每個宏對應的命令如下：
1）針對終端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）針對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）針對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）針對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）針對無線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
啟用Smartports的方式： Switch(config)# int fa0/19?? Switch(config-if)# macro apply cisco-desktop $access_vlan 1? //需要定義這個端口成為哪個VLAN的一部分 Switch(config-if)#show parser macro????????????????????????????????????????//這個命令會顯示每個宏所作的工作
當然，我們也可以自己定義一個宏： Switch(config)# macro name steven?????????????? switchport mode access spanning-tree portfast spanning-tree bpduguard enable switchport port-security maximum 1????????????????????????? //定義可以連接的設備的數(shù)量上限 switchport access vlan 1???????????????????????????????????????????? ?//將該端口歸入vlan1 @???????????????????????????????????????????????????????????????????????????????? //通過@符號結束宏 Switch(config)# interface gigabitethernet1/0/2??????????? //接口下啟用宏 Switch(config-if)# macro apply steven???
