This reports whether this SPAN monitoring session has been administratively enabled or disabled. Because a SPAN session mirrors live production traffic to a capture port, leaving it enabled indefinitely has an ongoing, if usually small, performance cost on the source ports, so admins toggle this off between capture windows rather than leaving every session running permanently. Setting this to 'disabled' for span-1 stops traffic mirroring without deleting the session's source/destination configuration, so it can be re-enabled later for another capture.
