Description: The block state of the port.
What is loopbackDetectionBlockState?
This object reports whether this port has been placed into a blocked state by the loopback detection feature, as an encoded value. An admin checks this to confirm whether a port is currently shut down due to a detected loop, which explains why traffic isn't passing through it. For example, seeing this object indicate a blocked state for a given port confirms the switch is actively suppressing traffic there because of loopbackDetectionProcessMode's portbased action.
