Changing the port configuration
Click the appropriate box to change the configuration.
Note
With various automatic functions, the device prevents or reduces the effect on other ports
and priority classes (Class of Service) if a port is overloaded. This can mean that frames are
discarded even when flow control is enabled.
Port overload occurs when the device receives more frames than it can send, for example as
the result of different transmission speeds.
