xStack L3網管型千兆光纖交換機
增強型L3千兆交換機，旨在連接安全園區或企業網絡中的最終用戶。
- 16個SFP端口
- 8個10/100 / 1000BASE-T / SFP組合端口
- 多種軟件管理選項
- 物理堆疊最多6個單元，總共288個千兆端口和高達40 Gbps的堆疊帶寬
- 廣泛的第2層功能，包括STP，ERPS和IGMP / MLD偵聽
- 全面的第3層功能，包括RIP，OSPF，IGMP / MLP
- 支持IPv6
標準和增強圖像DGS-3120系列嵌入了兩個不同的軟件映像-標準映像（SI）和增強型映像（EI）。標準映像為園區或企業使用提供了複雜的功能。除了高級L3功能外，增強型圖像還支持所有標準圖像功能。使用多個軟件映像，只需購買必需的功能，即可為軟件許可提供靈活的方法。
增強網絡可靠性DGS-3120系列面向需要高水平網絡安全性和最長正常運行時間的企業，園區和客戶。除DGS-3120-24SC-DC之外，DGS-3120系列中的所有型號均支持外部冗餘電源，以確保持續運行。
綜合安全DGS-3120系列為用戶提供最新的安全功能，例如帶有DHCP偵聽的多層和數據包內容訪問控制列表（ACL），風暴控制以及IP-MAC端口綁定（IMPB）。
身份驅動的網絡策略DGS-3120系列支持身份驗證機制，例如802.1X，基於Web的訪問控制（WAC）和基於MAC的訪問控制（MAC），以實現嚴格的訪問控制並易於部署。
