The Huawei S3300 series switches are new generation Layer 3 Ethernet switches developed to carry various services on the Ethernet, which provide powerful Ethernet functions for operators and enterprise customers. Based on the new generation high-performance hardware and Huawei Versatile Routing Platform (VRP), the S3300 provides the enhanced selective QinQ function and capability to replicate multicast packets between VLANs at the line speed, and supports carrier-class reliability technologies such as Smart Link (applicable to tree networks) and RRPP (applicable to ring networks), as well as the Ethernet OAM function. 

The S3300 can be used as access devices in buildings or applied to the access layer and aggregation layer of campus networks. The S3300 is easy to install. It supports automatic configuration and plug-and-play, which dramatically reduces costs of network deployment.

The S3300 is case-shaped with a height of 1 U. The S3300 series are classified into SI (standard) and EI (enhanced) models, including S3328TP-SI, S3328TP-EI, S3328TP-EI-24S, S3328TP-PWR-EI, S3352P-SI, S3352P-EI, S3352P-EI-24S, S3352P-EI-48S, and S3352P-PWR-EI. The SI models support Layer 2 functions and basic Layer 3 functions; the EI models support complex routing protocols and abundant services and features.
