Hello, friend!
As mentioned by the preceding friend, it is not recommended that the MA5620 be configured as a switch.
The network ports of the MA5620 cannot communicate with each other. Therefore, the MA5620 can function as a switch only after the isolation is canceled.
Log in to the MA5620 and run the display isolate all command to check whether all ports are isolated. Generally, isolation is enabled on the MA5620 by default. Therefore, you need to disable isolation.
You can run the uodo isolate port command to disable the isolation of each port.
Save the configuration.
Configure the MA5620 as a switch in a preceding way.
Thanks!
