Both management and maintenance network ports are used for device maintenance and management. Generally, the maintenance network ports are reserved for direct device connection at customers' sites, preventing access to the management networks of customers.

Difference between the inband management and out-of-band management
The differences of these two management modes lie in: Reliability: In out-of-band mode, when the service link is faulty, you can still log in to and manage the storage device by using the management link. Management mode: In out-of-band mode, either the ISM or CLI can be used for management. In inband mode, only the ISM can be used. Networking: In inband mode, management data and service data share the same link. Therefore, the number of network cables is reduced. Functions: In inband mode, the application server collaborates with the storage device. In some cases, the performance of the storage device is enhanced.

Accessing the management network port
For details about how to log in to the iMana CLI and WebUI, see the iMana User Guide (Link). For details about how to log in to the iBMC CLI and WebUI, see the iBMC User Guide (Link). Use HTTPS to access the WebUI. Enter https://bmc_ip_address/ in the browser's address box and press Enter. It is not recommended that you enter "bmc_ip_address" in the browser's address box and press Enter. If you enter only the IP address, HTTP will be used by default. The login may fail because HTTP poses security risks.

Whether the IP address of a maintenance network port can be changed
The IP address of a maintenance network port can be changed. You can use OceanStor DeviceManager or CLI to modify the IP address of a specified maintenance network port.

Network cable used on the management network port between devices for extended ECC communication
