As a network administrator,you have been instructed to prevent all traffic or iginating on the LAN from entering the R2 router.Which the following command would implement the access list on the interface of theR2 router?()
請參見圖示。網絡管理員需要設置 Switch1,用于從 HostA 進行遠程訪問。管理員在 Router1 上發(fā)出 show ip interface brief 命令,然后在 Switch1 上發(fā)出 show interfaces trunk 命令以檢驗當前狀態(tài)。此外,管理員還將圖中所示的其它配置應用于 Switch1。但是,從 HostA 嘗試 telnet 訪問卻失敗了。還需要對交換機發(fā)出哪些命令?()
