Parameters
count: Sets the maximum number of MAC addresses that can be learned on a port. When the argument
takes 0, the port is not allowed to learn MAC addresses. The value range varies with device models.
disable-forwarding: Disables the device from forwarding frames with unknown source MAC addresses
after the number of learned MAC addresses reaches the upper limit. Frames with the source MAC
addresses listed in the MAC address table are forwarded.
Usage guidelines
If the command is executed in interface view, the configuration takes effect on the interface.
