configure ports link-scan interval

configure ports link-scan interval [ milliseconds | default ] { slot [ slot | all ] }


Configures the link-scan interval. The configure command allows the user to set the interval in a range between the default for the platform and 500 ms. A higher interval can free up CPU cycles when fast link detection is not a requirement.
