The FSW-824P-4SFP+ switch is a high-performance Layer 2+ switching solution specifically engineered for aggregation and secondary distribution segments within complex network architectures. The hardware architecture is optimized for critical multicast traffic management, ensuring peak efficiency in the delivery of carrier-grade IPTV services sourced from professional Headend systems such as 3DG-FLEX and GALAXIA. Advanced IGMP Snooping integration enables dynamic traffic segmentation, preventing intra-VLAN packet flooding and ensuring stream integrity for UHD video surveillance and low-latency high-definition streaming.
The device's hardware configuration features 24 Gigabit Ethernet interfaces with support for IEEE 802.3af/at (PoE/PoE+) standards, providing a total PoE Power Budget of 370W for the direct power supply of high-consumption network equipment. These ports are complemented by 4 x 10Gbps SFP+ slots dedicated exclusively to high-bandwidth uplink functions or hardware stacking implementation. This stacking capability, restricted to devices within the same series, allows for centralized logical management via a single IP address, drastically simplifying routine maintenance operations and enhancing overall network backbone resilience.

Layer 2 Optimisation and Multicast Management
IGMP Snooping (v1/v2/v3): Performs packet inspection of control messages to generate the Multicast Forwarding Table (MFT). It isolates streams to ports with an active Join Report, reducing computational overhead on client devices.
IGMP Fast Leave: Terminates forwarding immediately upon detection of a Leave message without waiting for the standard query timeout. This reduces convergence times during channel switching and prevents bandwidth spikes.
MVR (Multicast VLAN Registration): Enables sharing a single Multicast Source VLAN across multiple user Receiver VLANs. It eliminates flow duplication in the backbone while maintaining unicast traffic isolation.
Access Control (ACL) and Security
IGMP Filter: Per-port policies that restrict subscriptions to specific multicast group IP addresses. It protects the switch's Control Plane from saturation and unauthorised access.
Transparent Pass-through: A bypass mode for the IGMP protocol on specific VLANs or interfaces, treating video traffic as native broadcast.
Hardware Protection & Storm Control: Architecture featuring hierarchical scheduling and suppression mechanisms for anomalous Broadcast, Multicast, and Unknown Unicast traffic. It supports privilege management via RBAC for CLI access.
QoS Policies and Performance
Bandwidth Control: Traffic management via CAR (Committed Access Rate) on a per-port or per-flow basis.
Scheduling Algorithms: Hardware queue management using SP (Strict Priority), WRR (Weighted Round Robin), or hybrid SP+WRR configurations.
