An engineer is starting to implement a wired 802.1X project throughout the campus. The task is for failed authentication to be logged to Cisco ISE and also have a minimal impact on the users. Which co

The `monitor-mode enabled` command on a switch port places the port in 802.1X monitor mode. In this mode, the port allows all traffic, even from unauthenticated users, but still sends EAPoL requests to the endpoint and logs authentication attempts (both successful and failed) to Cisco ISE. This allows for testing and logging without disrupting user access, thereby having minimal impact.

`authentication host-mode multi-auth` allows multiple authenticated hosts on a single port but doesn't specifically address monitoring or minimal impact during initial rollout.

`authentication open` allows all devices to connect without 802.1X authentication and would not log failed authentication attempts to ISE.

`pae dot1x enabled` is used to enable the Port Access Entity for 802.1X on the interface, which is part of enforcing 802.1X, not monitoring with minimal impact.
