22、序列在步驟中已經(jīng)列出九、共同思考1.如果要將特權(quán)模式密碼用密文顯示,用什么參數(shù)?(請用?查看2.如果在插槽2上的第2個快速以太網(wǎng)接口怎么表示?(f1/1十、課后練習(xí)請將所有地址改為10.0.0.0/24這個網(wǎng)段,重復(fù)以上配置。十一、相關(guān)命令詳解。show interface使用show interface全局配置命令配置接口狀態(tài)。show interfaceshow interface type interface-numbershow interface type slot/port(用于帶有非信道化E1的物理接口的路由器show interface serial slot/port:cha
