This write control, when set to true(1), immediately removes every alias entry from all of the alias tables on the device; reading it always returns false(2). An admin would use this as a bulk reset when the alias tables have become cluttered with stale data or when starting a clean discovery baseline, since it clears everything device-wide rather than entry by entry. For example, after a major network re-cabling project, an admin could set ctAliasEntryClearAll to true(1) to wipe out all the now-invalid old alias mappings at once instead of deleting them individually.
