スイッチから生成された設定の代わりに手動で作成された設定を使用すると、[置換の設定（Configure Replace）] が失敗することがあります。失敗の原因として考えられるのは、show running configuration に示されていないデフォルト設定の潜在的な違いです。次の例を参照してください。
power redundancy コマンドがデフォルトのコマンドである場合、デフォルトの設定では表示されません。ただし、ユーザーが show run all コマンドを使用した場合に表示されます。次の例を参照してください。
switch# show run all
!Command: show running-config all

構成置換のユーザー構成に power redundancy-mode ps-redundant コマンドが追加された場合、検証/コミットが失敗する可能性があります。次の例を参照してください。
switch# show file bootflash:test
!Command: show running-config

power redundancy-mode ps-redundant コマンドは、構成置換の後の show running には表示されません。したがって、「欠落」と見なされ、CR は失敗します。次に例を示します。
switch# config replace bootflash:test verify-and-commit
