S5750X-48T6Y-SI Key Features and Highlights
S5750X series switches deliver high switching capacity, advanced L3 features, and robust multicast support, making them ideal for high-density aggregation or core layers in campus and enterprise networks. With VSF virtualization, comprehensive QoS, and enhanced IPv6 support, these switches provide reliable, scalable, and secure network solutions.

Key Features and Highlights
-
Unique integrated external power supply mode
Integrated external power supply system: The power supply system is built into the fuselage, providing one or more DC trunk cables to the optical AP side. The optical AP then accesses the trunk cable through branch cables to power itself. -
Easy-to-use management and maintenance
Support zero-touch configuration, unified management and automatic distribution of network-wide versions and configurations, without manual intervention. Simplifies user operations and improves deployment reliability. Supports power failure alarm Dying GASP function.
When the system power is lost, SNMP alarm information is triggered to notify the remote network management platform. Supports complete Ethernet OAM technology (IEEE802.3ah/802.1ag), VCT, DDM (digital diagnostic monitoring), and other features for quick fault detection and reduced maintenance difficulty. -
Flexible and comprehensive security control strategy
VLAN-based DHCP snooping and IP Source Guard.
Supports custom ACLs, flexible matching of Ethernet/IP header rules, standard 802.1X authentication, extended 802.1X authentication, and Web Portal authentication.
Multiple security protection mechanisms: SYN Flood, Land, ICMP Flood, BPDU Guard, Root Guard, anti-attack technologies, avoids unexpected topology loops and illegal edge devices, prevents unnecessary topology oscillations.
Supports both port-based and RSPAN (remote port mirroring) anti-attack measures at the user level. -
VLAN switching, diverse development
Supports common QinQ and flexible QinQ technologies, maximum freedom to configure QinQ policies.
N:1 VLAN ID switching, N:1 VLAN Translation, converting VLAN Tags of access port messages into specified VLAN Tags for QoS policy convergence.
Supports multiple VLAN types: VLAN, MAC VLAN, Voice VLAN, etc., for multi-service converged networks. -
Flexible and scalable intelligent VSF stacking technology
Supports DCN VSF virtualization, connecting multiple devices through multiple connection methods and virtualizing them into a virtual device. Ensures consistency of virtualization functions, expands number of ports, bandwidth, and forwarding processing capabilities, and fully realizes elastic expansion. -
Comprehensive functions and excellent performance
Supports static routing, RIP v1/v2, RIPv6, OSPF, OSPFv3, IS-IS, IS-ISv6, BGP, BGP4+, ECMP, and routing strategies for complex large-scale networking.
Supports and provides ISATAP and 6TO4 automatic tunnels, transition technologies such as IPv6 over IPv4, IPany over GREv4, and IPany over GREv6 configuration tunnels, providing a stable IPv6 transition solution. -
Multiple management and monitoring methods
Supports standard SSH, SNMP v1/v2c/v3, Security IP function, and SYSLOG for easy search and positioning. Switch can only be configured and managed in a legal IP to prevent illegal users from logging into the switch.
Real-time monitoring of network management functions: anomaly monitoring, CPU utilization, stack anomalies, etc.
