cisco1812Jルーターの工場出荷設定への戻し方
cisco1812Jルーターの初期設定をする為に最初に向上出荷状態に戻したい。
ルーターといえばbuffaroな私はciscoのルーターなんて初めてですので、
何がなんだかわからない。とりあえず、中古で3200円で見つけましたので
おおー安い。会社の毎年の資格の目標も今年はciscoにしたいかなーなんて思っておりましたので、
購入したのですが、届いてびっくり。
なんと、設定にはcisco様専用のシリアルケーブルが必要！！amazonのプライムで注文して一日停止。
cisco様専用シリアルケーブルお写真
（片側がRJ45、もう片側がいわゆるシリアル（DB9）になっております）
届いてパソコンにつなげようとしたら今度はパソコン側にシリアルの指す所が無い。
しかし、マイコンピューターのデバイスマネージャーにはCOM1で認識されております。
もしやと思いパソコンを開けてみると、マザーボードにはしっかりと９本ピンのソケットが準備されておりましたが、
パソコンの筺体にはDB9の端子が無かったのです。
がーーん、で追加でUSB→シリアル変換のケーブルを購入してやっと接続できました。いつかはCOM1使ってやるぞ。
（ここの部品を調達するよりもUSB変換のほうが安いので・・・）
前置きが長くなりましたがここからが本題です。
手順
①CISCO1812Jの電源が切れていることを確認する。
②接続
パソコン→USBシリアル変換ケーブル→CISCO1812J
③テラタームを起動してシリアルポート設定で以下を確認
COMポートに「USBシリアル変換ケーブル」が認識されているポートを指定
データ：８ビット
パリティー：none
ストップ：１ｂｉｔ
フロー制御：none
④CISCO1812Jの電源を入れる。
⑤テラタームの画面に以下のような感じで文字が出始める。

⑥ここで「ALT+B」を押す。
何度も押しているとなんかたらタームが死んだような動作になったりしたので、
控えめに。電源投入後４数えてALT+Bが良いみたい。
⑦コマンド投入
monitor: command "boot" aborted due to user interrupt rommon 1 >
と出るとコマンドが入れられるので「confreg 0x2142」を投入
0x2142 はNVRAMから設定を読んでくれない。←工場出荷状態
0x2102 はNVRAMから設定を読んでくれる。←後でこっちで起動する
なので、初回2142で起動して色々設定した後にwriteしておいて、
もう一度ALT+Bをやって2102にしておくと良いみたい。
You must reset or power cycle for new config to take effect rommon 2 >
と出るので「reset」を投入
⑧ずらずらーっと流れて
Would you like to enter the initial configuration dialog?
と出るので「no」を投入。
⑨「Press RETURN to get started!」と出てからまたずらずらーっと流れて
*May 5 20:57:07.731: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2, changed state to down
で止まる。
でちょっと固まってみてたけど進まないみたいなので、さっき
「Press RETURN to get started!」と言っていたのを思い出しenterキーを押すと先に進める。
⑩Router> と出て一安心。
⑪「enable」を投入
⑫「erase startup-config」を投入
⑬「write」も投入。念のためだ。
⑭「reload」を投入
で再起動 ここでは上のCTRL+Bの場面は「0x2102 」で起動。
⑮「「enable」を投入
⑯「show config」を投入するとほぼ最小限のconfigになっている。
