 Ethernet is a data network communication technology based on CSMA/CD (Carrier Sense Multiple Access/Collision Detection), which utilizes a shared communication medium.  When the number of hosts increases, it can lead to severe issues like collisions, broadcast storms, performance degradation, and even network unavailability.

VLAN Configuration

 The MAC address table records MAC addresses, interfaces, and the associated VLAN information.  When the device forwards packets, it consults the MAC table.

QinQ Configuration

 MSTP (Multiple Spanning Tree Protocol) is a protocol for creating multiple spanning trees based on STP/RSTP.  Introduced in IEEE 802.

MSTP Configuration

 Link Aggregation combines multiple physical links into one logical link to increase bandwidth, achieve traffic load balancing, and improve link reliability.  Link aggregation has two modes static aggregation and dynamic aggregation.
