Disabling a port and then re-enabling it can result in the port staying DOWN.
Port stays DOWN and traffic is impacted.
Port Disable followed by Port Enable. The condition is aggravated when the port "enable" follows the "disable" too quickly. For example port "enable" within 15 seconds of the port "disable".
There is no guaranteed workaround. Sometimes disabling/re-enabling the port on the other side will bring the port back up. Also, waiting 30-45 seconds before re-enabling the port minimizes the risk of this issue occurring.
Improve port "disable" such that subsequent port "enable" does not leave the port DOWN.
