The S4804G has L2+ network management function, supports IPV4 management and static routing and forwarding, complete security protection mechanism, perfect ACL/QoS strategy and rich VLAN function, easy to manage and maintain. Support multiple network redundancy protocols STP/RSTP/MSTP (<50ms) to improve link backup and network reliability. When a one-way network fails, communication can be quickly restored to ensure uninterrupted communication for important transmissions. The switch supports flexible operation and maintenance management, and can be configured through various application services such as Web, CLI, SNMP, Telnet and other network management methods, port flow control, VLAN division, QoS and other functions. It can meet the multi-channel video surveillance and wireless coverage network application environment. Suitable for hotels, campuses, parks, supermarkets, scenic spots, factory dormitories and SMB small and medium-sized enterprises to form a cost-effective network.
