今回はCisco Switch(Catalyst 3560)のIOSファイルをリカバリー手順をメモしておきます。色々いじってやらかしてしまったときの自分用メモです。 とりあえず以下のサイトを見ておけば大丈夫だとおもいます。
Catalyst – xmodem
Send file by xmodem or kermit protocol with GNU screen
MODEボタンを長押しして起動させる
これすることでxmodemでファイルを送信できるようになるっぽい。IOSファイルをスイッチに転送する
接続環境はこんな感じです、Gentoo Linux(screenコマンド) <—-> Switch
手元のLinuxにバックアップしておいたIOSファイルをスイッチに転送します。そのためにLinux側に「sxコマンド」が必要になるのでインストールしておきます。
### コマンドのパッケージを検索
hiro-gentoo ~ # e-file sx
[I] net-dialup/lrzsz
Available Versions: 0.12.20-r3 0.12.20-r4
Last Installed Ver: 0.12.20-r4(2020年07月16日 20時08分31秒)
Homepage: https://www.ohse.de/uwe/software/lrzsz.html
Description: Communication package providing the X, Y, and ZMODEM file transfer protocols
Matched Files: /usr/bin/sx;
### インストールする
hiro-gentoo ~ # emerge -av net-dialup/lrzsz
### インストール完了
hiro-gentoo ~ # which sx
/usr/bin/sx「screenコマンド」でスイッチに接続してるターミナル上で以下を入力します。
### 受信を開始するコマンドっぽい
switch: copy xmodem: flash:c3560-ipbasek9-mz.122-44.SE6.bin
### 上記コマンドをスイッチ上で実行したら「screenコマンド」の機能を使ってIOSファイルを転送します
* 「ctrl + a」を押す
* 「:」を入力する
* 「exec !! sx c3560-ipbasek9-mz.122-44.SE6.bin」を入力する
* エンターでIOSファイルがローカルPCからスイッチに転送されます
Begin the Xmodem or Xmodem-1K transfer now...

### 転送完了。めちゃくちゃ時間かかります。（3時間ぐらい？）
