Class topic
Post 1. Service Types
Ethernet was founded in 1973 by Xerox and co-released by Xerox, Inter, and DEC, and is now used for a wide range of LAN technologies. ITU-T defines how to transmit Ethernet services on traditional TDM networks, that is, EoSDH... More
Post 2. TAG Attributes
When a data frame enters or leaves a port on an Ethernet board, the tag attribute of the port affects the processing mode of the data frame. The tag of the port on the Ethernet board is Tag Aware, Access, and Hybrid... More
Post 3. MTU,MFL and Jumbo Frames
Three key Ethernet features: MTU, MFL, and Jumbo frames, which directly affect the data transmission capability of the Ethernet... More
Post 4. How to Configure 10GE Services
With the development of science and society, 10 Gbit/s EPL Ethernet is widely used. Huawei's 10GE service solution in the field of transmission networks is mature. The configuration process is simple and maintenance is convenient... More
Post 5. Ethernet Configuration
When configuring Ethernet aggregation services, you need to select correct parameter settings based on user requirements... More
