The network layer generally wants to limit the maximum length of each packet sent. Any time the network layer receives an IP packet to send, it determines which local interface to send the data to and queries that interface to obtain its Maximum Transmission Unit (MTU). The network layer compares the MTU value with the length of the IP packet to be sent. If the length of the IP packet is greater than the MTU value, then the IP packet needs to be fragmented, and the length of the fragmented packe

By configuring the traffic statistics interval function of an interface, users can count and analyze the messages of interest. At the same time, network congestion and service interruption can be avoided by checking the traffic statistics of the interface in advance and taking timely measures for traffic control.

Split Stacking - If the current stacking system is no longer carrying services, this stacking system can be restored to a standalone environment, in which case a split-stacking operation is required.

For CloudEngine series switches, users can execute the command reset saved-configuration under user view to cancel specifying the configuration file to be used for the next system startup, so that the device starts up with the default configuration, that is, the factory settings are restored.
