How to set the MTU value of Huawei core switches
You can run the mtu command in the interface view to change the MTU of a Layer 3 interface. The MTU of an IP packet is the number of bytes from the IP header to the data of the packet. The IP layer then compares the MTU with. Correctly configuring the MTU value is a prerequisite to ensure normal and efficient communication between devices. - If the MTU is configured too small and the message size is large, it may result in too much message fragmentation, and the message may be discarded by the QoS queue, affecting.

Why is there no neutral wire in the distribution box
The primary reason a neutral wire is often missing in older switch boxes is due to a wiring configuration known as a switch loop. In this historical setup, the power source, or line, first runs directly to the light fixture box, and only two wires are extended down to the switch. The neutral wire in a residential electrical circuit serves as the return path for the electrical current, completing the circuit back to the electrical panel and the utility transformer. It is insulated and carries current under normal conditions back to the transformer. Second question: the code now (I believe beginning in 2011) requires the neutral at most switch locations but there are also many exceptions, e. closets, non-habitable rooms, switches installed with conduit to allow for. Circuits use hot, neutral, and ground wires. Clearly, neutrals are vital components of every home.

Excess wire ends at the top of the distribution box
Service loops are excess cable (slack) that is designed to be in addition to any cable needed for the actual planned drop (run) length and terminations. Service slack is found at both ends of the permanent link in a structured cabling system. The required length of wire left inside an electrical box is a matter of safety and future maintenance, ensuring that devices can be installed and serviced without complication. This saves time and reduces cost. This loop prevents water from traveling along the cable into. Ideally, wire groups are installed in layers and wires are bent at right angles to buses or breakers. Label short sheathing sections (slugs) to indicate which circuits wires serve. Labeling cables at outlets is important so that when it comes time to attach wires to devices, you'll always know.
