FAQ-A Service Is Configured from Port IP3 of Board A to Port IP4 of Board B. When ALS or LPT Is Enabled, the Service Port Is Abnormally Disabled. Why

Issue Description
A service is configured from port IP3 of board A to port IP4 of board B. When ALS or LPT is enabled, the service port is abnormally disabled. Why? 
Alarm Information
Handling Process
The ALS/LPT function is realized by port instead of by timeslot. Hence, the ALS/LPT function is available only when the ports are symmetric. The T2000 configures services in an end-to-end manner. Therefore, the situation where the timeslots of ports are inconsistent does not occur. Therefore, you need to ensure that IP ports of the two ends are consistent with each other before configuring the services between the two ports. That is, configure a service from port IP3 of board A to port IP3 of board B.
The TN11LOM board only supports the end-to-end service configuration. Hence, this problem need not be solved.
