When you want to start the MLLP listener, you enable the MLLP port. When you want to shut down the MLLP listener, you disable the MLLP port. Disabling the MLLP port blocks incoming requests from reaching the MLLP listener. When the MLLP port is disabled, clients receive an error message when they issue requests to it.

You can use the Integration Server Administrator to enable or disable the MLLP port. On the Security > Ports screen, find the MLLP port in the list of ports and change the status in the Enabled column to Yeswhen you want to enable the port. When you want to disable the port, change the status to No.

Another way to enable or disable the MLLP port is to enable or disable the package associated with the port. For the procedure how to enable or disable a port, see the webMethods Integration Server Administrator’s Guide for your release.
