• VLAN Management: Supports up to 4094 VLANs, including Private VLAN, Stacked VLAN, Tagged VLAN, and Port‑based VLAN. Guest VLAN and port‑based authentication provide secure guest access.
• Spanning Tree Protocol (STP): IEEE 802.1D/802.1w/802.1s with loop protection, BPDU filtering, and rapid convergence for resilient link redundancy.
• Link Aggregation: LACP support for bandwidth scaling and fault tolerance across multiple links.
• Quality of Service (QoS): Class‑of‑Service tagging, traffic classification, and priority queuing with 8 queues to guarantee performance for latency‑sensitive applications.
• Security: 802.1X RADIUS authentication, SSH/SSL/TLS management, MAC address filtering, and ACL support for granular access control.

High Performance & Reliability

The DGS 3630‑28SC delivers a switching capacity of 128 Gbps with a throughput of 95.24 Mpps. It features:

• Jumbo Frames: Support up to 12,000 bytes for efficient large‑payload transfers.
• IGMP Snooping & Multicast Support: Optimizes multicast traffic handling and reduces unnecessary broadcast storms.
• ARP Inspection & MAC Address Table: 68,000 entries with dynamic learning and static overrides to prevent spoofing attacks.
• Port Mirroring: Enables traffic analysis for troubleshooting and security monitoring.

Management & Monitoring Capabilities

The switch offers a comprehensive suite of management protocols and interfaces, ensuring seamless integration into existing network operations centers (NOCs):

• Web‑Based Management: Intuitive GUI for configuration, monitoring, and firmware updates.
• SNMP v1/v2c/v3: Full support for network management systems.
• NTPv3/v4: Accurate time synchronization across the network.
• Telnet & SSH: Secure command‑line access with encryption.
• Console Port: RJ‑45 or Mini‑USB for out‑of‑band management.

Environmental & Compliance Standards

The DGS 3630‑28SC meets stringent global certifications, ensuring reliability and safety across diverse operating conditions:

• EMC/EMI: CE, FCC Class A, C‑Tick, VCCI, BSMI, CCC.
• Operating Temperature: -5 °C to 50 °C (in use); -40 °C to 70 °C (storage).
• Humidity: 10–95 % RH during operation; 5–95 % RH for storage.
• Safety: cUL, CB, CE, CCC, BSM certifications.

Stacking & Redundancy Features

The switch supports virtual stacking of up to 32 units, allowing administrators to create a single logical device from multiple physical switches. This feature simplifies management, enhances bandwidth aggregation, and provides high availability through redundant links and power supplies.

• Stacking Protocol: Proprietary DGS stack protocol with fast convergence.
• Redundant Power Supply: Optional dual PSUs for uninterrupted operation.
