This write-only object triggers the switch to apply the pending APS admin mode change previously staged in redPortPendingAdminMode. Admins write commit(1) to this object as the final step of a two-phase configuration process, ensuring a staged role change (e.g., to working or protection) takes effect only when explicitly committed. For example, after setting redPortPendingAdminMode to unprotected, an admin writes commit(1) to redPortCommit to actually put the port into unprotected mode; reading this object back yields implementation-specific, not meaningful, results.
