Extreme Networks 08G20G4-48P以太网交换机
1.产 品 资 料 介 绍：
- 48 口全千兆高密度接入架构：作为 08G20G4-24P 的端口升级款，08G20G4-48P 提供 48 个 10/100/1000Base-T 电口，搭配 4 个 SFP 千兆光口，电口数量翻倍，可同时接入 48 台终端设备（如 PC、IP 电话、高清摄像头），单设备即可覆盖中型企业办公区、大型连锁门店、小型数据中心接入层等高密度场景，相比 2 台 24 口交换机减少机柜空间占用 50%，降低设备堆叠带来的管理复杂度。
- 翻倍性能支撑大规模业务：整机交换容量提升至 96Gbps，包转发率达 71.4Mpps，支持全千兆无阻塞传输，能稳定承载多部门并发办公、32 路以上 4K 监控回传、多组视频会议等大规模业务，避免因端口扩容导致的性能瓶颈；同时优化数据缓存机制，单端口缓存容量提升至 2MB，可应对突发流量冲击，减少高峰时段的数据丢包，保障业务流畅性。
- 强化 PoE + 供电覆盖能力：若设备延续 PoE + 特性，单端口最大输出 30W，总 PoE 功率预计达 370W-500W，可同时为 48 台 PoE 终端供电（实际数量需结合设备功耗，如摄像头约 15W / 台、AP 约 20W / 台），无需额外部署多台 PoE 注入器或交换机，尤其适配大型监控系统、无线覆盖密集的场景，简化布线的同时降低供电成本。
- 专业托管型管理升级：继承 Web 图形化界面与 CLI 命令行操作，新增 “端口分组管理” 功能，可按部门、区域将 48 个电口分组配置 VLAN、QoS 策略，避免单端口逐一设置的繁琐；支持 SNMP v3 协议与 Enterasys OneControl 平台深度对接，可同时监控多台 48 口交换机的端口状态、流量分布，批量下发配置模板，大幅提升大规模网络的运维效率。
- 多层级可靠性保障强化：除 STP/RSTP/MSTP 生成树与 LACP 链路聚合外，新增 “端口冗余备份” 功能，可将空闲电口设置为关键终端（如服务器、核心摄像头）的备用端口，故障时自动切换；同时优化风暴抑制算法，支持基于端口的广播 / 组播 / 单播风暴阈值自定义，精准拦截不同区域的异常流量，防止大规模网络因局部故障瘫痪。
Extreme Networks 08G20G4-48P以太网交换机 英文资料：
48 port full gigabit high-density access architecture: As an upgraded version of the 08G20G4-24P port, the 08G20G4-48P provides 48 10/100/1000Base-T electrical ports, paired with 4 SFP gigabit optical ports, doubling the number of electrical ports. It can simultaneously access 48 terminal devices (such as PCs, IP phones, high-definition cameras), covering high-density scenarios such as medium-sized enterprise office areas, large chain stores, and small data center access layers with a single device. Compared with 2 24 port switches, it reduces cabinet space occupation by 50% and reduces management complexity caused by device stacking.
Doubling performance to support large-scale business: the entire machine's switching capacity has been increased to 96Gbps, with a packet forwarding rate of 71.4Mbps, supporting full gigabit non blocking transmission, and able to stably carry large-scale business such as multi department concurrent office work, more than 32 4K monitoring feedback channels, and multiple video conferences, avoiding performance bottlenecks caused by port expansion; Simultaneously optimizing the data caching mechanism, the single port cache capacity has been increased to 2MB, which can cope with sudden traffic shocks, reduce data packet loss during peak hours, and ensure business smoothness.
Strengthening PoE+power coverage capability: If the device continues the PoE+feature, the maximum output of a single port is 30W, and the total PoE power is expected to reach 370W-500W, which can simultaneously power 48 PoE terminals (the actual number needs to be combined with device power consumption, such as cameras about 15W/unit and APs about 20W/unit), without the need to deploy multiple PoE injectors or switches, especially suitable for large monitoring systems and wireless coverage intensive scenarios, simplifying wiring while reducing power supply costs.
Professional hosted management upgrade: Inheriting the Web graphical interface and CLI command line operation, adding the "Port Group Management" function, which can group 48 electrical ports by department and region to configure VLAN and QoS policies, avoiding the tedious process of setting up a single port one by one; Support deep integration between SNMP v3 protocol and Enterasys OneControl platform, which can simultaneously monitor the port status and traffic distribution of multiple 48 port switches, issue configuration templates in batches, and greatly improve the operational efficiency of large-scale networks.
Multi level reliability assurance enhancement: In addition to STP/RSTP/MSTP spanning tree and LACP link aggregation, a "port redundancy backup" function has been added, which can set idle electrical ports as backup ports for critical terminals (such as servers and core cameras) and automatically switch in case of failure; Simultaneously optimize the storm suppression algorithm, support port based broadcast/multicast/unicast storm threshold customization, accurately intercept abnormal traffic in different regions, and prevent large-scale networks from being paralyzed due to local failures.
