Percentage of available bandwidth on the channel that can be reserved for admitted/active service flows before the channel goes into Level 2 Overload. When a channel goes into Level 2 Overload, a warning message will be logged. Service flow activation/admission will not be denied in Level 2 Overload. A channel in Level 2 Overload is a good candidate for overload control or load balancing actions. If the percentage is set to 0, the default value will be used and reading this object must return the the default L2 threshold. If a set operation tries to change the value of an existing instance of this object to any value that is higher than cadIfDownChannelCACL3Threshold or lower than cadIfDownChannelCACL1Threshold on the same row, then an 'inconsistentValue' error must be returned.
