配置標准ACL:
router(config)# access-list Access-List-Number [ permit deny ] source [ source-mask ]
<-- Access-List-Number 范圍:
1~99標准ACL;100~199擴展ACL;800~899標准IPX ACL;
900~999擴展IPX ACL;1000~1099 IPX SAP ACL;600~699Apple Talk ACL-->
router(config)# interface Type Port
router(config-if)# ip access-group Access-List-Number [ in out ]
router(config-if)# ^z
配置擴展ACL:
router(config)# access-list Access-List-Number [ permit deny ] [ Protocol Protocol-Number ] source source-wildcard [ Source-Port ] destination destination-wildcard [ Destination-Port ] [ established ]
router(config)# interface Type Port
router(config-if)# ip access-group Access-List-Number [ in out ]
router(config-if)# ^z
配置命名ACL:
router(config)# ip access-list [ standard extended ] ACL-Name
router(config [ std- ext- ] nacl)# [ permit deny ] [ IP-Access-List-Test-Conditions ]
router(config [ std- ext- ] nacl)# no [ permit deny ] [ IP-Access-List-Test-Conditions ]
router(config [ std- ext- ] nacl)# ^z
router(config)# interface Type Port
router(config-if)# ip access-group [ACL-Name 1~199 ] [ in out ]
router(config-if)# ^z
配置DCE時鐘:
router# show controllers Type Port <--確定DCE接口-->
router(confin-if)# clock rate 64000 <--進入DCE接口設置時鐘速率-->
router(config-if)# ^z
配置PPP協議:
router(config)# username Name passWord Set-Password-Here <--驗證方建立數據庫-->
router(config)# interface Type Port
router(config-if)# encapsulation ppp <--啟動PPP協議-->
router(config-if)# ppp outhentication [ chap chap pap pap chap pap ] <--選擇PPP認證-->
router(config-if)# ppp pap sent-username Name password Password <--發送驗證信息-->
router(config-if)# ^z
PAP單向認證配置實例:
驗證方:
router-server(config)# username ClIEnt passWord 12345 <--驗證方建立數據庫-->
router-server(config)# interface serial 0
router-server(config-if)# encapsulation ppp
router-server(config-if)# ppp authentication pap <--選擇使用PAP實現PPP認證-->
router-server(config-if)# ^z
被驗證方:
router-client(config-if)# encapsulation ppp
router-client(config-if)# ppp pap sent-username Client password 12345 <--發送驗證信息-->
router-client(config-if)# ^z
PAP雙向認證配置實例:
路由器 A:
routerA(config)# username B password 12345
routerA(config)# interface serial 0
routerA(config-if)# encapsulation ppp
routerA(config-if)# ppp authentication pap
routerA(config-if)# ppp pap sent-username A password 54321
routerA(config-if)# ^z
路由器 B:
routerB(config)# username A password 54321
routerB(config)# interface serial 1
routerB(config-if)# encapsulation ppp
routerB(config-if)# ppp authentication pap
routerB(config-if)# ppp pap sent-username B password 12345
