We have discussed Huawei S12700, S9700 and S12700 modular switches in the last thread about Huawei switch products. Today, let's explore Huawei fixed switches.

 

Distinguish Switch Models Based on Layer 3 Features

Huawei fixed switches consist of the S1700, S2700, S3700, S5700 and S6700 series.

In terms of product functions, the S1700, S2700, S5700LI are Layer 2 switches, while the S3700, S5700 (except the S5700LI) and S6700 are Layer 3 switches.

(Compared with Layer 2 switches, Layer 3 switches support Layer 3 features such as dynamic routing protocols in addition to Layer 2 features. I have made a summary in the Tips at the bottom of the post to tell you what Layer 3 features are.)

 

Diversified S5700 Models Adapt to Customers' Requirements

The S5700 series is the first series developed by Huawei for enterprise networking and has the most product models. Why is the S5700LI a Layer 2 switch, different from other S5700s?

The S5700LI, which is a lightweight S5700 model and a star product of Huawei, is designed to accommodate customized demands of various projects. For example, in a project, the customer wanted a bargain because he just wanted to use S5700s for transparent transmission and did not need Layer 3 features on the switch. But he also pointed out that the S5700 must have forty-eight GE electrical interfaces.

While there are demands for lightweight S5700s, there are demands for enhanced S5700s. Therefore, Huawei developed an enhanced version (S5700EI) and an advanced version (S5700HI). In addition, the standard version of the S5700 was renamed S5700SI following consistent naming conventions. The richness of functions and features provided by these versions is in the following order: S5700LI < S5700SI < S5700EI < S5700HI. The following table lists their support for differences features.

S6700, Keystone in the Era of the 10GE Ports

Huawei developed the S6700EI based on the S5700 to embrace the era of 10GE ports.

Figure 3 S6700EI

 

The S6700 is one of the switches featuring an industry-leading performance and provides a maximum of 48 line-rate 10GE ports.

l  In data centers, the S6700 switches function as access switches to provide 10G access.

l  On a campus network, the S6700 switches connect to access switches through GE interfaces, and connect to core switches through 10GE optical interfaces, providing a large switching capacity. The network provides 10 Gbit/s rate for the backbone layer and 100 Mbit/s access rate for terminals, meeting requirements for high bandwidth and multi-service operations.

 

S2750, Designed for 100M-to-the-Desktop Access

While the S6700 switches provide a solution to the 10GE backbone, Huawei developed the 100M switch S2750 as a solution to 100M-to-the-desktop.

On a campus network, the S2750 switches connect to terminals using 100M electrical interfaces, and connect to aggregation switches using GE interfaces. With functions such as PoE, voice VLAN and NAC, the S2750 provides various desktop access functions.

 

Summary of Fixed Switches' Network Locations

The S3700 also has 100M downstream interfaces and can be considered an S2700 with some Layer 3 features. Huawei has stopped releasing new versions of the S3700 since 2014. The S1700 can be seen as a hardware branch model of the S2700. Here, I am not going to waste your time nagging more. In conclusion, the following table lists the recommended deployment locations of Huawei fixed switches on networks:
