Mô tả
- Số cổng: 48 cổng 10/100/1000 Mbps + 2 cổng Gigabit RJ45/SFP combo.
- Hiệu suất: Khả năng chuyển mạch 100 Gbps, Tốc độ chuyển tiếp 74.4 triệu gói mỗi giây (wire-speed performance).
- Layer 2: Gom cổng lên đến 8 nhóm, tối đa 8 cổng cho mỗi nhóm với 16 cổng ứng viên cho mỗi nhóm (dynamic) cho việc tổ hợp liên kết 802.3ad.
- QoS (Chất lượng Dịch vụ): 8 hàng đợi phần cứng cho các mức ưu tiên, Lập lịch ưu tiên nghiêm ngặt và tròn robin có trọng số (WRR). Phân bổ hàng đợi dựa trên DSCP và lớp dịch vụ (802.1p/CoS).
Đặc tính kỹ thuật
| Model | SG220-50-K9-EU |
| Performance | |
| Switching capacity and forwarding rate | Capacity in Millions of Packets per Second (mpps) (64-byte packets): 74.4 Switching Capacity in Gigabits per Second (Gbps): 100 |
| Jumbo frames | Frame sizes up to 9216 supported |
| MAC table | Up to 8192 MAC addresses |
| Total system ports | 50 Gigabit Ethernet |
| RJ-45 ports | 48 Gigabit Ethernet |
| Uplink ports | 2 Gigabit Ethernet combo |
| Layer 2 Switching | |
| Spanning Tree Protocol (STP) | Standard 802.1d STP support Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default |
| Port grouping | Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP): Up to 8 groups, Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation |
| VLAN | Support for up to 256 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN |
| Auto voice VLAN | Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS |
| QinQ VLAN | VLANs transparently cross a service provider network while isolating traffic among customers |
| Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) | Protocols for automatically propagating and configuring VLANs in a bridged domain |
| Head-Of-Line (HOL) blocking | HOL blocking prevention |
| Loopback detection | Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP. |
| Automatic Media-Dependent Interface Crossover (MDIX) | Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed. |
| Security | |
| ACLs | Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag Support up to 512 rules |
| Port security | Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses |
| IEEE 802.1X (authenticator role) | 802.1X: RADIUS authentication; guest VLAN; |
| RADIUS, TACACS+ | Supports RADIUS and TACACS authentication; switch functions as a client |
| MAC address filtering | Supported |
| Storm control | Broadcast, multicast, and unknown unicast |
| DoS protection | DOS attack prevention |
| STP Bridge Protocol Data Unit (BPDU) Guard | This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port |
| Spanning Tree Loop Guard | This feature provides additional protection against Layer 2 forwarding loops (STP loops). |
| Secure Shell (SSH) Protocol | SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported |
| Secure Sockets Layer (SSL) | SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch |
| Quality of Service | |
| Priority levels | 8 hardware queues |
| Scheduling | Strict priority and weighted round-robin (WRR) Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS) |
| Class of service | Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ) |
| Rate limiting | Ingress policer, per VLAN and per port |
| Environmental | |
| Dimensions (W x H x D) | 440 x 44 x 201 mm |
| Unit weight | 3.3 kg |
| Power | 100 to 240V 50 to 60 Hz, internal |
– Bảo hành: 12 tháng.
