CatalystのIOSフィーチャーセット入れ替え
本日Catalyst3560V2(WS-C3560V2-TS-S)を入手しました。やったー！これならIOS15も正式サポートしてるからCCIE Ver5の学習でも使えるぜー！
で、当然TS-Sなので初期状態ではipbaseのIOSが入ってます。なのでこれをipservicesk9にあげようとしたところ…
Error: The image in the archive which would be used to upgrade Error: system number 1 does not support the same feature set.
あれ？サポートしてるIOSなのに蹴られた…ダメなの？
と思ってググるさんにエラーメッセージの内容投げてみたらここに行き着いた。
Cat0-3750 upgrade. Error: system number 1 does not support the same feature
It seems that Cisco has added a check into there upgrade process to prevent you from accidentally changing the feature set during an IOS upgrade. This is a really nice sanity check since changing feature sets on a production switch could really ruin your day.

To bypass this check, add the /allow-feature-upgrade parameter to the archive download-sw command. According to the documentation, this feature is new as of 12.2(35).
どうやら12.2(35)でフィーチャーセット変更に関するチェックが追加されたみたいです。うーむ。知らんかった。で、ここで言われてる通り /allow-feature-upgrade をつけてやってみました。
