技術の進歩目覚ましいWiFiの世界であっという間に一線を退いた Cisco Aironet AP1252AG、AP1262N を一時的に再利用しようと、コンソールから以前の設定を 初期化 して基本的なWiFiの設定を追加しました。
Aironet AP1252AGの初期化
まず1台目がこちらのCisco Aironet AP1252AG、金属筐体でかなり重いので、アンテナに荷重が掛からないように置かないと、重みでアンテナが損傷することも。

底面のコンソール端子にケーブルをつなぎ、Ubuntu 18.04母艦のシリアルターミナルに繋いで電源ON。

- delete flash:private-multiple-fs
- delete flash:private-config
- rename flash:config.txt flash:config.old

通常起動後、確認するとだいぶ以前の設定が消えたように思えたのですが、設定をよく確認するとネットワーク設定の一部が残っていました。

電源プラグを抜いて、本体底面のコンソール端子隣にある MODE スイッチを押したまま、電源プラグを挿して起動させることで上記のうち、 BVI1 インターフェイスの固定IPアドレスは消えました。

最後まで残った ip name-server 設定は個別に削除して、ようやく初期状態まで戻すことができました。

Aironet AP1252AGの基本設定
初期化されたAP1252AGでは、LANポートは既にDHCPクライアントモードになっていたので、これをそのまま利用することにして、必要なWiFiプロファイルと機器の基本設定を以下の要領で発行しました。
