Extreme Networks 08G20G4-24P托管交换机
1.产 品 资 料 介 绍：
- 24 口全千兆接入架构：作为企业级托管交换机，08G20G4-24P 提供 24 个 10/100/1000Base-T 电口，部分版本可能包含 4 个 SFP 千兆光口，电口满足 PC、IP 电话、监控摄像头等终端的高密度千兆接入，光口则支持与核心交换机的长距互联，单设备可覆盖中小型企业办公区、连锁门店的全终端接入需求，避免多台低端交换机堆叠导致的管理复杂问题。
- 专业托管型管理能力：区别于非托管交换机，该设备支持 Web 图形化管理界面与 CLI 命令行操作，可实现精细化网络配置 —— 如划分 VLAN 隔离部门网络、设置 QoS 优先级保障语音 / 视频业务带宽、配置端口聚合提升链路带宽，同时支持 SNMP v3 协议对接 Enterasys OneControl 管理平台，实现多交换机集中监控、批量配置与故障告警，大幅降低企业运维难度。
- 高可靠业务承载设计：整机交换容量达 48Gbps（若含光口则更高），包转发率 35.7Mpps，支持全千兆无阻塞传输，能稳定承载多用户并发办公、4K 监控回传、视频会议等高频业务，避免因带宽瓶颈导致的卡顿或丢包；内置 STP/RSTP/MSTP 生成树协议，可自动阻断网络环路，配合链路聚合（LACP）功能，构建无环冗余网络，保障业务连续运行。
- 接入层深度安全防护：具备多层次安全管控功能，支持 802.1X 端口认证与 MAC 地址绑定，仅允许授权设备接入网络，防范非法终端入侵；内置 ACL 访问控制列表，可基于 IP 地址、端口号、应用类型过滤数据，阻止外部恶意访问与内部非授权数据传输；同时支持 DHCP Snooping，防止非法 DHCP 服务器分配错误 IP，保障网络地址管理秩序。
- 灵活的场景适配能力：若设备支持 PoE + 供电（部分版本特性），单端口最大输出 30W，总 PoE 功率可达 370W，可直接为无线 AP、高清摄像头、IP 电话供电，无需额外部署电源与 PoE 注入器，简化布线；SFP 光口可搭配单模 / 多模光模块，突破铜缆 100 米传输限制，适配跨楼层、跨区域的组网需求，兼顾本地接入与长距互联。
Extreme Networks 08G20G4-24P托管交换机 英文资料：
24 port full gigabit access architecture: As an enterprise level managed switch, the 08G20G4-24P provides 24 10/100/1000Base-T electrical ports, and some versions may include 4 SFP gigabit optical ports. The electrical ports meet the high-density gigabit access needs of terminals such as PCs, IP phones, and surveillance cameras, while the optical ports support long-distance interconnection with core switches. A single device can cover the full terminal access needs of small and medium-sized enterprise office areas and chain stores, avoiding the management complexity caused by stacking multiple low-end switches.
Professional managed management capability: Different from unmanaged switches, this device supports a web graphical management interface and CLI command line operation, which can achieve fine network configuration - such as dividing VLAN isolated departmental networks, setting QoS priority to ensure voice/video business bandwidth, configuring port aggregation to improve link bandwidth, and supporting SNMP v3 protocol docking with the Enterasys OneControl management platform to achieve centralized monitoring, batch configuration, and fault alarm of multiple switches, greatly reducing the difficulty of enterprise operation and maintenance.
High reliability service carrying design: The entire machine has a switching capacity of 48Gbps (even higher if optical ports are included), a packet forwarding rate of 35.7Mpps, supports full gigabit non blocking transmission, and can stably carry high-frequency services such as multi-user concurrent office work, 4K monitoring feedback, video conferencing, etc., avoiding lag or packet loss caused by bandwidth bottlenecks; Built in STP/RSTP/MSTP spanning tree protocol, which can automatically block network loops and, in conjunction with Link Aggregation (LACP) function, build a redundant network without loops to ensure continuous business operation.
Deep security protection at the access layer: It has multi-level security control functions, supports 802.1X port authentication and MAC address binding, only allows authorized devices to access the network, and prevents illegal terminal intrusion; Built in ACL access control list, which can filter data based on IP address, port number, and application type to prevent external malicious access and internal unauthorized data transmission; Simultaneously supporting DHCP Snooping to prevent illegal DHCP servers from assigning incorrect IP addresses and ensure orderly network address management.
Flexible scene adaptation capability: If the device supports PoE+power supply (some version features), the maximum output of a single port is 30W, and the total PoE power can reach 370W. It can directly power wireless APs, high-definition cameras, and IP phones without the need for additional deployment of power supplies and PoE injectors, simplifying wiring; SFP optical ports can be paired with single-mode/multi-mode optical modules, breaking through the 100 meter transmission limit of copper cables, adapting to cross floor and cross regional networking needs, and balancing local access and long-distance interconnection.
