9 IPv6 over IPv4隧道配置关于本章IPv6 over IPv4隧道技术的出现解决了IPv4网络向IPv6网络过渡的问题。
说明S2700不支持IPv6 over IPv4隧道，只有S3700支持IPv6 over IPv4隧道功能。
9.1 IPv6 over IPv4隧道概述IPv6 over IPv4隧道可实现IPv6网络孤岛之间通过IPv4网络互连。
9.2 设备支持的IPv6 over IPv4隧道特性设备支持的IPv6 over IPv4隧道特性包括双协议栈、IPv6 over IPv4隧道。
9.3 配置IPv4/IPv6双协议栈为了实现IPv6 over IPv4隧道，需要在IPv4网络与IPv6网络交界的边界设备上启动IPv4/IPv6双协议栈。
9.4 配置IPv6 over IPv4隧道用户可以配置IPv6 over IPv4隧道，利用IPv4网络连接IPv6网络。
9.5 配置举例9.1 IPv6 over IPv4隧道概述IPv6 over IPv4隧道可实现IPv6网络孤岛之间通过IPv4网络互连。
由于IPv4地址的枯竭和IPv6的先进性，IPv4过渡为IPv6势在必行。
因为IPv6与IPv4的不兼容性，所以需要对原有的IPv4设备进行替换。
但是如果贸然将IPv4设备大量替换所需成本会非常巨大，且现网运行的业务也会中断，显然并不可行。
所以，IPv4向IPv6过渡是一个渐进的过程。
在过渡初期，IPv4网络已经大量部署，而IPv6网络只是散落在各地的一个个“孤岛”，IPv6 over IPv4隧道就是通过隧道技术，使IPv6报文在IPv4网络中传输，实现IPv6网络之间的孤岛互连。
9.2 设备支持的IPv6 over IPv4隧道特性设备支持的IPv6 over IPv4隧道特性包括双协议栈、IPv6 over IPv4隧道。
说明S2700不支持IPv6 over IPv4隧道，只有S3700支持IPv6 over IPv4隧道功能。
9路由关于本章本章主要介绍关于IPv4路由的相关信息和配置的方法。
在因特网中进行路由选择要使用路由器，路由器根据所收到的报文的目的地址选择一条合适的路由（通过某一网络），将报文传送到下一个路由器，路由中最后的路由器负责将报文送交目的主机。
9.1 IPv4路由介绍关于IPv4路由表、IPv4静态路由和全局参数的基本知识和配置方法。
9.1 IPv4路由介绍关于IPv4路由表、IPv4静态路由和全局参数的基本知识和配置方法。
9.1.1 IPv4路由表路由器转发分组的关键是路由表。
每个路由器中都保存着一张路由表，表中每条路由项都指明分组到某子网或某主机应通过路由器的哪个物理端口发送，然后就可到达该路径的下一个路由器，或者不再经过别的路由器而传送到直接相连的网络中的目的主机。
背景信息IPv4的查询功能可以查询路由表的全部信息，包括动态路由表和静态路由表的信息。
操作步骤步骤1单击导航树中的“路由 > IPv4路由 > IPv4路由表”菜单，进入“IPv4路由表”界面。
步骤2设置查询条件。
步骤3单击“查询”，查询列表区显示出所有符合条件的记录。
----结束9.1.2 IPv4静态路由配置静态路由是一种特殊的路由，它由管理员手工配置而成。
通过配置静态路由可建立一个互通的网络，但这种配置问题在于：当发生网络故障后，静态路由不会自动发生改变，必须有管理员的介入。
背景信息在交换机上配置IPv4静态路由时，建议明确指定下一跳地址。
因为交换机的物理接口多为广播类型的以太网接口，在同一出接口下可以关联多个下一跳地址，从而无法唯一确定下一跳。
在应用中，如果必须指定出接口，应同时指定通过该接口发送时对应的下一跳地址。
操作步骤●新建IPv4静态路由a.单击导航树中的“路由 > IPv4路由 > IPv4静态路由配置”菜单，进入“IPv4静态路由配置”界面。
b.单击“新建”，进入“新建IPv4静态路由”界面。

2.1 VLAN概述介绍VLAN的定义、由来和作用。
VLAN（Virtual Local Area Network）即虚拟局域网，是将一个物理的LAN在逻辑上划分成多个广播域的通信技术。
以太网是一种基于CSMA/CD（Carrier Sense Multiple Access/Collision Detection）的共享通讯介质的数据网络通讯技术。
当主机数目较多时会导致冲突严重、广播泛滥、性能显著下降甚至造成网络不可用等问题。
通过交换机实现LAN（Local AreaNetwork）互连虽然可以解决冲突严重的问题，但仍然不能隔离广播报文和提升网络质量。

1.8 常见配置错误介绍链路聚合常见配置错误的处理方法。
1.1 链路聚合概述介绍链路聚合的定义、由来和作用。
链路聚合（Link Aggregation）是将—组物理接口捆绑在一起作为一个逻辑接口来增加带宽和可靠性的一种方法。
链路聚合组LAG（Link Aggregation Group）是指将若干条以太链路捆绑在一起所形成的逻辑链路，简写为Eth-Trunk。
随着网络规模不断扩大，用户对链路的带宽和可靠性提出越来越高的要求。
在传统技术中，常用更换高速率的接口板或更换支持高速率接口板的设备的方式来增加带宽，但这种方案需要付出高额的费用，而且不够灵活。
采用链路聚合技术可以在不进行硬件升级的条件下，通过将多个物理接口捆绑为一个逻辑接口，实现增加链路带宽的目的。
链路聚合的备份机制能有效提高可靠性，同时，还可以实现流量在不同物理链路上的负载分担。
如图1-1所示，DeviceA与DeviceB之间通过三条以太网物理链路相连，将这三条链路捆绑在一起，就成为了一条Eth-Trunk逻辑链路，这条逻辑链路的带宽等于原先三条以太网物理链路的带宽总和，从而达到了增加链路带宽的目的；同时，这三条以太网物理链路相互备份，有效地提高了链路的可靠性。

Each port delivers 15.4 W PoE or 30 W PoE+ power capacity.PoE power is divided into two types: 500W and 250W power supplies.S2700-9TP-PWR-EI Built-in single powersupply - 124 W PoE (15.4W): 8PoE+ (30W): 4S2700-26TP-PWR-EI W0PSA2500 - 123.2 W PoE (15.4W): 8PoE+ (30W): 4W0PSA5000 - 369.6W PoE (15.4W): 24PoE+ (30W): 12W0PSA2500 W0PSA2500 246.4W PoE (15.4W): 16PoE+ (30W): 8W0PSA5000 W0PSA5000 739.2W PoE (15.4W): 24PoE+ (30W): 24 S2700-52P-PWR-EI W0PSA2500 - 123.2 W PoE (15.4W): 8PoE+ (30W): 4W0PSA5000 - 369.6W PoE (15.4W): 24PoE+ (30W): 12W0PSA2500 W0PSA2500 246.4W PoE (15.4W): 16PoE+ (30W): 8W0PSA5000 W0PSA5000 739.2W PoE (15.4W): 48PoE+ (30W): 24S2750-20TP-PWR-EI-AC Built-in single powersupply - 370W PoE (15.4W): 16PoE+ (30W): 12S2750-28TP-PWR-EI-AC Built-in single powersupply - 370W PoE (15.4W): 24PoE+ (30W): 12When a switch has two power supplies installed, the two power supplies work in redundancy mode to provide power for the switch itself and in load balancing mode to provide power for powered devices (PDs).Product Features and HighlightsEasy Operation●The S2700 supports Huawei Easy Operation function. Thanks to this function, the S2700 implements easy installation, configuration, monitoring, and troubleshooting, greatly reduces initial installation and configuration costs, improves upgrade efficiency and lowers engineering costs. It provides a Web network management system (NMS) with a user-friendly graphical user interface (GUI) to implement alarm management and visual configuration, facilitating operation and maintenance. In addition, it supports faulty device replacement without configuration.●The S2700 offers a new application-specific integrated circuit (ASIC) switching technique and a fan-free design. This design reduces mechanical faults and protects the device against damages caused by condensed water and dust. Flexible service control●The S2700-EI supports various ACLs. ACL rules can be applied to VLANs to flexibly control ports and schedule VLAN resources.●The S2700 supports port-based VLAN assignment, MAC address-based VLAN assignment, protocol-based VLAN assignment, and network segment-based VLAN assignment. These secure and flexible VLAN assignment modes are used in networks where users move frequently.●The S2700 supports GARP VLAN Registration Protocol (GVRP), which dynamically distributes, registers, and propagates VLAN attributes to ensure correct VLAN configuration and reduce network administrator workloads. In addition, the S2700 supports SSH v2, HWTACACS, RMON, and port-based traffic statistics. The network quality analyzing (NQA) function assists users with network planning and upgrades.Excellent security features●The S2700 supports DHCP snooping, which generates user binding entries based on users' access interfaces, MAC addresses, IP addresses, IP address leases, VLAN IDs. The DHCP snooping function protects enterprises from common attacks such as bogus IP packet attacks, man-in-the-middle attacks, and bogus DHCP server attacks.●The S2700 can limit the number of MAC addresses that can be learned on an interface to prevent attackers from exhausting MAC address entries by using bogus source MAC addresses. This function minimizes packet flooding, which occurs when users' MAC addresses cannot be found in the MAC address table. The S2700 can also limit the number of ARP entries to prevent ARP spoofing attacks. In addition, it provides an IP source check function to prevent malicious users from using spoofed IP addresses to initiate DoS attacks.●The S2700 supports centralized MAC address authentication and 802.1x authentication. It authenticates users based on statically or dynamically bound user information such as IP address, MAC address, VLAN ID, access interface. VLANs, QoS policies, and ACLs can be dynamically applied to users.PoE function●The S2700 PWR series support improved Power over Ethernet (PoE) solutions and you can determine whether a PoE port provides power and the time a PoE port provides power. The S2700 PWR can use PoE power supplies with different power levels to provide the PoE function. Powered devices (PDs) such as IP Phones, WLAN APs, and Bluetooth APs can be connected to the S2700 PWR through network cables. The S2700 PWR provides -48V DC power for the PDs.●In its role as power sourcing equipment (PSE), the S2700 PWR complies with IEEE 802.3af and 802.3at (PoE+), and can work with PDs that are incompatible with 802.3af or 802.3at (PoE+). Each port provides a maximum of 30 W of power, complying with IEEE 802.3at. The PoE+ function increases the maximum power available on each port and implements intelligent power management for high-power consumption applications. This process facilitates the ease of PD use. PoE ports are still able to work while in power-saving mode.High scalability●The S2700 uses Intelligent Stack (iStack) to virtualize multiple switches into a single logical device to ease user management and configuration and expand the system switching capacity. iStack improves switching capacity, reliability, and scalability. Additionally, after the stack is established, all the member switches in a stack use the same IP address. You can use a single IP address to manage and maintain the switches uniformly. This greatly reduces system operation and maintenance (O&M) costs.●The iStack stacking architecture is designed for rapid failover capability with n-1 master redundancy, distributed Layer 2 and Layer 3 switching, link aggregation across the stack, and within 200 millisecond failover for path failure and hitlessmaster/backup failover.●Besides traditional STP, RSTP, and MSTP, the S2700 supports enhanced Ethernet technologies such as Smart Link and RRPP, implements millisecond-level protection switchover for links, and ensures the network quality.●The S2700 supports Smart Ethernet Protection (SEP) protocol, a ring network protocol applied to the link layer of an Ethernet network. SEP provides millisecond-level service switchovers and ensures nonstop forwarding of services. In addition, SEP features simplicity, high reliability, high switchover performance, convenient maintenance, and flexible topology and enables users to manage and plan networks conveniently.●The S2700 supports G.8032 Ethernet Ring Protection Switching (ERPS). The ERPS is based on traditional Ethernet MAC and bridging functions. It uses the mature Ethernet OAM and Ring Automatic Protection Switching (Ring APS or R-APS) technologies to implement millisecond-level protection switching on Ethernet. ERPS supports various services and flexible networking and lowers operating expense (OPEX) and capital expenditure (CAPEX) of users.Comprehensive QoS policies●The S2700 supports complex traffic classification based on packets' TCP/UDP port numbers, VLAN IDs, source MAC/IP addresses, destination MAC/IP addresses, IP protocols, or priorities. By limiting the traffic rate based on traffic classification results, the S2700 implements line-speed forwarding on each port to ensure high-quality voice, video, and data services. Each port supports a maximum of eight queues and multiple queue scheduling algorithms, such as WRR, SP, and WRR+SP. Powerful surge protection capability●The S2700 uses the Huawei patented surge protection technique that supports 7 kV surge protection capability on service ports. This effectively protects switches against over lightning induced overvoltage. The Huawei patented surge protection technique greatly reduces the possibility of equipment being damaged by lightning, even in extreme situations or in scenarios where grounding is not feasible.Quiet operation, energy conservation, and low radiationThe S2700 uses an energy-saving integrated circuit design to ensure even heat dissipation. Idle ports can enter a sleep mode to further reduce power consumption. The S2700 generates no sound because it does not contain any fans. Radiation produced by the S2700 is within the standard range for electric appliances and causes no harm to the human body.

11策略路由配置关于本章通过配置策略路由，可以用于提高网络的安全性能和负载分担。
11.1 配置策略路由配置策略路由可以将到达接口的转发报文重定向到指定的下一跳地址。
11.2 配置举例配置示例中包括组网需求和配置思路等。
11.1 配置策略路由配置策略路由可以将到达接口的转发报文重定向到指定的下一跳地址。
背景信息通过配置重定向，设备将符合流分类规则的报文重定向到指定的下一跳地址。
包含重定向动作的流策略只能在全局、接口或VLAN的入方向上应用。
说明对于S2700系列交换机，只有S2700-52P-EI和S2700-52P-PWR-EI交换机支持策略路由。
前置任务在配置策略路由前，需要完成以下任务：●配置相关接口的IP地址和路由协议，保证路由互通。
●如果使用ACL作为策略路由的流分类规则，配置相应的ACL。
操作步骤1.配置流分类a.执行命令system-view，进入系统视图。
b.执行命令traffic classifier classifier-name [ operator { and | or } ]，创建一个流分类并进入流分类视图，或进入已存在的流分类视图。
and表示流分类中各规则之间关系为“逻辑与”，指定该逻辑关系后：▪当流分类中有ACL规则时，报文必须匹配其中一条ACL规则以及所有非ACL规则才属于该类；▪当流分类中没有ACL规则时，则报文必须匹配所有非ACL规则才属于该类。
or表示流分类各规则之间是“逻辑或”，即报文只需匹配流分类中的一个或多个规则即属于该类。
缺省情况下，流分类中各规则之间的关系为“逻辑与”。
c.请根据实际情况定义流分类中的匹配规则。
d.执行命令quit，退出流分类视图。
2.配置流行为a.执行命令traffic behavior behavior-name，创建一个流行为，进入流行为视图。
b.请根据实际需要进行如下配置：▪执行命令redirect ip-nexthop ip-address &<1-4> [ forced ]，将符合流分类的报文重定向到下一跳。
当存在多个下一跳时，设备按照主备方式对报文进行重定向转发。
一个流行为中最多可以配置4个下一跳，设备根据下一跳的配置顺序确定主备链路，先配置的下一跳IP地址优先级较高。
配置的第一个下一跳IP地址作为主用链路，其它链路作为备用链路。
当主用链路Down之后，则自动选取优先级高的下一跳作为新的主链路；当原主用链路恢复正常以后，流量再回切至原主用链路。
说明通过配置报文重定向功能可以实现策略路由。
▪执行命令redirect ip-multihop { nexthop ip-address } &<2-4>，将符合流分类的报文重定向到配置的多个下一跳中的一个。
如果配置了多个下一跳，设备按照等价路由负载分担方式对报文进行重定向转发。
使用重定向到多下一跳的正常转发过程中，如果当前下一跳对应的出接口状态突然为Down，或路由突然发生了改变，设备可将链路快速切换到当前可用的某个下一跳对应的出接口上。
如果设备上没有命令中下一跳IP地址对应的ARP表项，使用此命令能配置成功，但重定向不能生效，设备仍按报文原来的目的地址转发，直到设备上有对应的ARP表项。
说明不能在同一流行为中既配置remark destination-mac又配置以下命令：●redirect ip-nexthop●redirect ip-multihopc.（可选）执行命令statistic enable，使能流量统计功能。
d.执行命令quit，退出流行为视图。
e.执行命令quit，退出系统视图。
3.配置流策略a.执行命令system-view，进入系统视图。
b.执行命令traffic policy traffic-policy-name，创建一个流策略并进入流策略视图，或进入已存在的流策略视图。
c.执行命令classifier classifier-name behavior behavior-name，在流策略中为指定的流分类配置所需流行为，即绑定流分类和流行为。
d.执行命令quit，退出流策略视图。
e.执行命令quit，退出系统视图。
4.应用流策略–在接口上应用流策略i.执行命令system-view，进入系统视图。
ii.执行命令interface interface-type interface-number，进入接口视图。
说明目前只有S2700-52P-EI、S2700-52P-PWR-EI、S2710-SI和S3700支持Tunnel接口配置。
iii.请根据不同设备形态进行如下配置：○在除S2700-52P-EI和S2700-52P-PWR-EI之外的其他S2700EI设备上，执行traffic-policy policy-name { inbound | outbound }命令，在接口上应用流策略。
对于除S2700-52P-EI和S2700-52P-PWR-EI之外的其他S2700EI设备，只有在流行为中配置了流镜像功能，才可以将流策略应用于出方向。
即出方向流策略只支持流镜像功能。
在配置流镜像之前，需要首先使用observe-port（本地镜像）或者observe-port（远程镜像）命令配置镜像端口。
○在S2700-52P-EI、S2700-52P-PWR-EI、S2710SI、S3700SI、S3700EI设备上，执行traffic-policy policy-name inbound命令，在接口上应用流策略。
每个接口的每个方向上能且只能应用一个流策略，但同一个流策略可以同时应用在不同接口的不同方向。
应用后，系统对流经该接口并匹配流分类中规则的入方向或出方向报文实施策略控制。
但是流策略对VLAN 0的报文不生效。
建议不要在Untagged类型接口出方向上应用包含有remark8021p、remark vlan-id等动作的流策略，否则，可能导致报文内容出错。
–在VLAN上应用流策略i.执行命令system-view，进入系统视图。
ii.执行命令vlan vlan-id，进入VLAN视图。
iii.执行命令traffic-policy policy-name inbound，在VLAN上应用流策略。
应用后，系统对属于该VLAN并匹配流分类中规则的入方向报文实施策略控制。
但是如果匹配到VLAN 0报文，则流策略不生效。
–在全局应用流策略i.执行命令system-view，进入系统视图。
ii.执行命令traffic-policy policy-name global inbound，在全局应用流策略。
检查配置结果●执行命令display traffic classifier user-defined [ classifier-name ]，查看已配置的流分类信息。
●执行命令display traffic behavior user-defined [ behavior-name ]，查看已配置的流行为信息。
●执行命令display traffic policy user-defined [ policy-name [ classifierclassifier-name ] ]，查看用户定义的流策略的配置信息。
●执行命令display traffic-applied [ interface [ interface-type interface-number ] | vlan [ vlan-id ] ] inbound [ verbose ]，查看全局、VLAN或接口上关联的ACL规则和流动作信息。
●执行命令display traffic policy { interface [ interface-type interface-number ][ inbound ] | vlan [ vlan-id ] [ inbound ] | global [ inbound ] }，查看已配置的流策略信息。
●执行命令display traffic-policy applied-record [ policy-name ]，查看指定流策略的应用记录。
11.2 配置举例配置示例中包括组网需求和配置思路等。
11.2.1 配置策略路由示例(S2700-52P-EI、S2700-52P-PWR-EI、S3700SI、S3700EI)组网需求如图11-1所示，公司用户通过Switch双归属到外部网络设备。
其中，一条是低速链路，网关为20.1.20.1/24；另外一条是高速链路，网关为20.1.30.1/24。
公司希望上送外部网络的报文中，IP优先级为4、5、6、7的报文通过高速链路传输，而IP优先级为0、1、2、3的报文则通过低速链路传输。
图11-1配置策略路由组网图20.1.20.1/2420.1.30.1/24配置思路采用重定向方式实现策略路由，进而提供差分服务，具体配置思路如下：1.创建VLAN并配置各接口，实现公司和外部网络设备互连。
2.配置ACL规则，分别匹配IP优先级4、5、6、7，以及IP优先级0、1、2、3。
3.配置流分类，匹配规则为上述ACL规则，使设备可以对报文进行区分。
4.配置流行为，使满足不同规则的报文分别被重定向到20.1.20.1/24和20.1.30.1/24。
5.配置流策略，绑定上述流分类和流行为，并应用到接口Eth0/0/3的入方向上，实现策略路由。
操作步骤步骤1创建VLAN并配置各接口# 在Switch上创建VLAN100和VLAN200。
