What are the functions of the MGMT port/HA port/Console port on GCC6021?
The installation methods supported by different models are as follows:
- MGMT port: used for remote management and monitoring of the device. Use a network cable to directly connect the computer to the MGMT port of the device, and log in to the device through the pre-configured IP address (192.168.1.1) of the MGMT port for Web management.
- HA port: used to achieve high availability between devices.
- Console port: used for initial configuration and subsequent management, using a serial line to interact directly with the command line interface of the device. Serial port login does not involve the network layer and does not require the IP address of the device, but requires the account and password for logging in to the device.
