How can I use the partial zoom-in function of VCN3020?

You can run the stack member member-id renumber new-member-id [ inherit-config ] command to change the stack member ID.
- If the inherit-config parameter is specified, the switch inherits the original stack configuration after it restarts, including the stack priority, stack domain ID, connection mode, and physical member port configuration. The common service port configuration, such as the port split configuration, will be lost, but the split configuration of physical member ports will be inherited.
- If the inherit-config parameter is not specified, the current stack configuration and common service port configuration are lost after the switch restarts. The configuration related to the new stack member ID in the configuration file takes effect.
- If the configuration file contains offline configuration for the new stack member ID, do not specify inherit-config in the command.

Scalable Video Coding (SVC) enables transmission of video in a large video format at a low bandwidth, for example, transmission of 1080p video at 512 kbit/s. The VP9000 series MCU supports the SVC protocol, but it must be enabled on the MCU. To enable the SVC function, perform the following operations: 1. Log in to the MCU as the administrator user in SSH2 mode. 2. Run the system view conf-policy enable-svc 1 command to enable the SVC function. 3. Run the save command to save the settings.

Method of disabling the digital zoom function of a camera: A camera uses digital zoom after maximum optical zoom, and the image quality decreases.
