全面的安全管理
• 用户策略和主机完整性强制执行以及身份管理
• 统一端口动态安全文件在网络中提供了精细的安全策略
• 威胁监测和响应工具通过CLEAR-Flow安全规则引擎对网络入侵做出响应
• 拒绝服务(DoS)保护和IP安全可抵御“中间人”欺骗和DoS攻击,加固网络基础架构
灵活的端口配置
所有型号的前面板或者后面板上都拥有4个SFP 1GbE端口。12、24和48端口10/100/1000型号中大多数型号的1GbE端口都支持通过软件许可升级为10Gb SFP+以太网口。请注意扩展温度型号不支持10GbE升级。另外,在24和48端口10/100/1000交换机的前面板上有4个1GbE
SFP复用端口(不适用于16541)。
扩展的温度范围支持X440-G2有3个型号支持 0⁰C to 60⁰C运行范围(型号16539,16540和16541)。多达8台X440-G2交换机支持通过SummitStack-V进行堆叠。每一台X440-G2交换机通过一个SFP+端口提供2个堆叠端口,扩展温度范围的交换机除外。标准的10Gb以太网光模块和无源及有源线缆能用于SFP+端口
通过SummitStack-V将X440-G2交换机堆叠到一起。SUMMITSTACK-V—通过SFP+端口的灵活堆叠
ExtremeXOS支持SummitStack-V功能,它使用X440-G2上的2个SFP+端口作为堆叠口,可使用10GbE SFP+的标准线缆和光模块技术,同时提供长达40km的远距离堆叠,简化了堆叠方案的线缆复杂
度。SummitStack-V与运行同样ExtremeXOS版本(21.1或者更高)带10Gb上联的X450-G2交换机、带10Gb上联的X460-G2交换机以及X670-G2和X770交换机兼容。SummitStack-V启用的端口必须物理上直连。
极进交换X440-G2支持复杂和智能的2层交换,以及包括基于策略的交换/路由在内的3层IPv4/IPv6路由,运营商桥接,出入双向访问控制列表,并且对于出入双向提供8Kbps细粒度的带宽控制。
IEEE 802.3AT POE-PLUS
IEEE 802.3af PoE已经广泛应用于企业园区网络边缘,给诸如无线接入点、语音IP电话以及安防摄像头等以太网设备供电。以太网端口扩展器例如极进网络的ReachNXT™ 100-8t也能够利用PoE,让安装和管理更加简易并且减少维护成本。通过将功率上限增加到30w,以及使用LLDP实现功率协商的标准化,更新的IEEE 802.3at PoE+标准增强了以太网供电技术。X440-G2支持IEEE 802.3at PoE+以及现在和未来与标准兼容PoE设备。
The Extreme Switching X440-G2 series switches are based on Extreme Networks® ExtremeXOS®, an adaptable operating system that provides continuous uptime, manageability, and operational efficiency. Each switch provides consistent high-performance, non-blocking hardware technology, continuing the extreme network tradition of simplifying network deployment by using common hardware and software in the network. The extreme Exchange X440-G2 switch is a cost efficient campus edge switch that supports the IEEE802.3at PoE+ standard.
Comprehensive security management
User policy and host integrity enforcement and identity management
• The Unified Port Dynamic Security file provides sophisticated security policies in the network
Threat detection and response tools respond to network intrusions with the CLEAR-Flow security rule engine
Denial of service (DoS) protection and IP security harden network infrastructure against “man-in-the-middle” spoofing and DoS attacks
Flexible port configuration
All models have four SFP 1GbE ports on the front or rear panel. 12, 24, and 48-port 1GbE ports in most models of 10/100/1000 models support software license upgrades to 10Gb SFP+ Ethernet ports. Note that the extended temperature model does not support the 10GbE upgrade. In addition, there are four 1Gbes on the front panel of the 24 and 48-port 10/100/1000 switches
SFP multiplex port (not available for 16541).
Extended temperature range support The X440-G2 is available in 3 models supporting 0⁰C to 60⁰C operating range (models 16539,16540 and 16541). Up to eight X440-G2 switches can be stacked using SummitStack-V. Each X440-G2 switch provides two stack ports through one SFP+ port, except for switches that extend the temperature range. Standard 10Gb Ethernet optical modules and passive and active cables can be used for SFP+ ports
Run the SummitStack-V command to stack X440-G2 switches. SUMMITSTACK-V – Flexible stacking through SFP+ ports
ExtremeXOS supports SummitStack-V, which uses 2 SFP+ ports on the X440-G2 as stackports, uses 10GbE SFP+ standard cable and optical module technology, and provides long distance stacking up to 40km, simplifying the cable complexity of stacking solutions
Degree. SummitStack-V is compatible with X450-G2 switches running the same ExtremeXOS version (21.1 or higher) with 10Gb connections, X460-G2 switches with 10Gb connections, and X670-G2 and X770 switches. SummitStack-V The port that is enabled must be physically directly connected.
Extreme Switching The X440-G2 supports complex and intelligent Layer 2 switching, as well as Layer 3 IPv4/IPv6 routing including policy-based switching/routing, carrier bridging, inbound and outbound bidirectional access control lists, and provides 8Kbps fine-grained bandwidth control for inbound and outbound bidirectional.
IEEE 802.3AT POE-PLUS
IEEE 802.3af PoE is already widely used at the edge of enterprise campus networks to power Ethernet devices such as wireless access points, voice IP phones, and security cameras. Ethernet port extenders such as the ReachNXT™ 100-8t for extreme networking can also leverage PoE, making installation and management easier and reducing maintenance costs. The updated IEEE 802.3at PoE+ standard enhances Power over Ethernet technology by increasing the power ceiling to 30w and standardizing power negotiation using LLDP. The X440-G2 supports IEEE 802.3at PoE+ and current and future standards-compatible PoE devices.
