Huawei SSN1EMS4 Board Product Overview Huawei SSN1EMS4 Board is an Ethernet switching processing board, which is mainly used to solve telecommunication application fields such as Ethernet service access, bandwidth management, and Ethernet service layer 2 switchings. A typical networking application of the Ethernet switch processing board is shown in Figure 1. It can implement Ethernet access and aggregation, Layer 2 switching of Ethernet data, port isolation, flow classification, data flow control, VLAN management, and priority. Configuration and other data features, as well as functions such as data encapsulation/decapsulation, virtual concatenation, and SDH mapping / demapping. At the same time, it can be connected with broadband access equipment and data communication equipment to provide a network-wide solution. Huawei SSN1EMS4 Board Product Feature Supports PORT-based transparent transmission. Support EVPL services that share PORTs. Support EVPL services that share VCTRUNK.
