使用 TFTP 還原 IOS 映像檔, 與設定內容的備份/還原練習 (CNA-04-003)

CCNA Exploration 4.0 第四學期上課檔案 (CNA-04-003), 使用 TFTP 還原 IOS 映像檔, 與設定內容的備份/還原練習.

• CNA-04-003.pkt, (Backup Link)

這個例子純粹只是提供一個簡單的 Packet Tracer 環境, 讓大家可以練習與感覺一下, Cisco IOS 映像檔 (Image file) 如何還原, 與設定內容 (Configuration) 的備份與還原.

不過, 如果各位有真實的 Router/Switch, 還是盡量以真實的機器練習, 畢竟 Packet Tracer 只是模擬器! 同時還少了很多, 例如 IOS 映像檔備份這個方向的練習。
