System Manager uses specific ports when it accesses the storage system by using management protocols such as HTTPS, HTTP, and SNMP.
System Manager uses the following ports to communicate with the storage systems:
It is best to use HTTPS for secure communication with the storage system. You must enable SSL on your storage system to allow administrative requests over HTTPS to succeed. For storage systems running clustered Data ONTAP 8.1 or later, if SSL is not enabled, you have to enable SSL from the command-line interface (CLI).
System Manager does not allow you to specify a port range to start the Jetty Web server. System Manager either allows you to select a specific port or automatically selects the port. If you manually specify the port, you can start only one instance of System Manager. Running a single instance does not allow multiple users to access the application simultaneously. For example, in a multiuser environment with a terminal server, if System Manager does not start with a predefined port range, multiple users cannot access the application simultaneously.
