Description
Huawei S1720-28GWR-4X-AC with 24 10/100/1000BASE-T ports, is one of the Huawei S1700 series switches. The S1700 is deployed at the access layer of an enterprise network to deliver cost-effective packet switching capability. In addition, the S1700 provides multi-service access capabilities, excellent extensibility, Quality of Service (QoS) guarantee, powerful multicast replication, and carrier-class security, and can be used to build ring topologies of high reliability. The S1700 series switches are applicable to various scenarios, for example, GE access to enterprise networks and GE-todesktop, building future-oriented IT networks for enterprises.
