Ethernet switches are one of the products which Huawei engineers are most familiar with. The complicated models, various specifications and similar names often confuse people. I always have to turn to a lot of reference material, checking and comparing, when asked about the differences in models and specifications as well as in features. As the saying goes, prolonged illness makes a doctor of a patient. I have summarized some rules of the switches to share.



An Unspoken Rule of Naming Huawei Modular Switches

Huawei switches consist of the S1700, S2700, S3700, S5700, S6700, S7700, S9700 and S12700 series, following the unspoken rule in the industry that bigger numbers indicate higher performances. First, let's make a comparison among the S7700, S9700 and S12700 series.

The last two figures in the names of Huawei modular switches represent the number of service slots. For example, "S12712" represents that this model has 12 service slots. The following pictures show all the modular switches of Huawei, including two models of the S12700, three models of the S9700 and three models of the S7700.

Three Modular Switch Series Have Witnessed the Network Development

Huawei developed the S7700 as core switches at the first stage of network development.

Increasing network scale and bandwidth requirements brought about higher requirements for switches' performances at the second stage of network development. Huawei developed the more powerful S9700 series. Then the S7700 switches were positioned as core switches for medium-scale enterprises and aggregation switches for large-scale enterprises. Meanwhile, Huawei started developing CE series data center switches to adapt to rapid development of data center networks.

At the third stage of network development, the network demand increased significantly and the requirements for quick response became higher and higher. Huawei developed the S12700 series agile switches which could also be used as enterprise core switches. The agile switches enable complex service requirements to be satisfied in as short as 6 months, compared to the 3-year period on traditional switches. In the meantime, Huawei upgraded the S7700 and S9700 to agile switches based on the S12700 development experience.

The following table and picture show the recommended locations of modular product models (take the S12700 as an example).

Agile Switches Amaze the World

Huawei implemented many new functions on the S12700 based on customer requirements in the first six months (October 2013 to April 2014) since the lunch. In addition, Huawei shared these functions on the S9700 and S7700. Concurrently, Huawei is trying to develop fixed agile switches to share all the functions of the S12700.

The following table lists the main feature changes of modular product models in 2014 (to be updated continuously):
