H3C配置案例大全(内部分享)

光纤链路排错经验一、组网：用户采用4台S5500作为接入交换机、1台S5500作为核心交换机组网，4台接入交换机分别在三个仓库以及门卫处与核心机房都是通过2根八芯单模光纤走地井连接，在这5个机房再通过跳纤来连接到交换上。

用户要求实现内网的用户主机访问公共服务器资源，并实现全网互通。

组网如下图所示：二、问题描述：PC现无法访问server服务器，进一步发现S5500光纤端口灯不亮，端口信息显示down状态。

在核心交换机端通过自环测试发现该端口以及光模块正常，接入交换机端也同样测试发现正常。

监控网络正常使用，再将网络接口转接到监控主干链路上，发现网络同样无法正常使用。

三、过程分析：想要恢复链路，首先要排查出故障点，根据故障点情况结合实际恢复链路通畅。

在这里主要分析光纤通路，光信号从接入交换机光口出来通过跳线，转接到主干光纤，然后再通过核心跳线转接到核心交换上。

由于该链路不通，首先要排除两端接口以及光模块问题，这里使用自环检测(如果是超远距离传输光纤线缆需要接光衰然后在自环，防止烧坏光模块)。

当检测完成发现无问题，再测试接入端的光纤跳纤：如果是多模光纤可以将一端接到多模光纤模块的tx口，检测对端是否有光；单模光纤如果没有光功率计可以使用光电笔检测(该方法只能检测出中间无断路，并不能检测出线路光衰较大的情况)。

最后再检测主线路部分，检测方式同跳线一样。

光路走向流程如图所示：四、解决方法：从上述的分析可以看出，只要保证了光信号一出一收两条路径都能正常就可以解决用户无法访问服务器的问题。

为了保证光路正常通路，最好的解决方法就是，通过使用光功率计来检测对端发射光在本端的光功率是否在光口可接受范围内。

由于用户组网使用了一些监控设备来接入该主干光缆，并且该光路现正常使用，通过将网络光纤转接到该监控主干光缆，发现网络光路仍然不通；并且两端端口自环检测正常。

由此可以判断出主要问题在两端的跳纤上。

如图所示：在没有光功率计并且客户业务又比较着急恢复的情况，可以先将两端的接入跳纤更换。

特定的通信方之间在IP层通过加密与数据源验证等方式，来保证数据报在网络上传输时的私有性、完整性、真实性和防重放。

IPsec通过AH（Authentication Header，认证头）和ESP（Encapsulating Security Payload，封装安全载荷）这两个安全协议来实现上述目标，并且还可以通过IKE（Internet Key Exchange，因特网密钥交换协议）为IPsec提供自动协商交换密钥、建立和维护安全联盟的服务，以简化IPsec 的使用和管理。

H3C和CISCO交换机做聚合配置实例教学

H3C和CISCO交换机做聚合配置实例教学H3C和CISCO交换机做聚合配置实例教学端口聚合也叫做以太通道，主要用于交换机之间连接。

那么两种不同的交换机怎么做聚合配置呢?下面跟yjbys店铺一起来看看H3C和CISCO交换机做聚合配置实例教程，希望对同学们学习交换机有所帮助!一、网络环境本网络是xx大厦，3台交换机做端口聚合的课题网络环境：H3C_A交换机<----------------->H3C_B交换机<----- ----------------------->cisco(3560)交换机H3C_B交换机做为中心交换机由于带宽需要，加上该9楼上了很多美国著名的avocentKVM的监控设备，需要很大的带宽，因此做了4组的端口链路聚合的需要因此以下配置命令1、H3C_A的.配置如下：(动态链路聚合，LACP默认启动)[H3C_A]sys[H3C_A]int bridge-aggregation 1[H3C_A]link-aggregation mode dynamil[H3C_A]int giabthernet1/0/26[H3C_A_giabthernet1/0/26]duplex full[H3C_A_giabthernet1/0/26]speed 1000[H3C_A_giabthernet1/0/26]port link-type trunk[H3C_A_giabthernet1/0/26]port trunk permit vlan all因此，其它三个端口都是一样，如以上配置就可以了，同时H3C_B也是同样如H3C_A的配置一样，配好了，检查下端口的问题。

2、思科的配置[cisco]int port-channel 2[cisco]swit trunk encapsulation dot1q[cisco]swit mode trunk[cisco]swit trunk allowed vlan all[cisco]进入端口模式配置[cisco]int gig0/19[cisco]duplex full[cisco]speed 1000[cisco]swit trun encapsulation dot1q[cisco]swit mode trunk[cisco]swit trunk allowed vlan all[cisco]channel-group 2 mode active其它的端口同样的配置配置好了在H3C交换机用 dis link-aggregation summary查看信息同时，在思科交换机用show ethernetchannel summary查看信息最后经过上面的配置，端口聚合就可以通了。

• DHCP Server 分配 IP 地址时，不能将 DNS Server 的 IP 地址分配出去，所以需要将 DNS Server 的 IP 地址配置为不参与自动分配的 IP 地址。

h3c交换机设置教程图解(实例)

交换机设置教程图解(2010-07-13 11:01:03)标签：电脑vlandhcp服务器lease最近在单位用Linux做了一台DHCP服务器，使用H3C S7506R交换机做中继，为两个VLAN提供DHCP服务，经过两个月的测试效果很好。

在这里把服务器和交换机的设置方法写出来供有相似需求的朋友参考。

首先贴一下网络拓扑：此主题相关图片如下dhcp中继.jpg：一DHCP服务器设置步骤如下：1)安装好Linux操作系统，我用的发行版本是CentOS 5.2。

2)设置服务器的网络参数如下IP地址:192.168.6.7子网掩码:255.255.255.0网关:192.168.6.254DNS:192.168.6.103)安装DHCP服务CentOS和Red Hat Enterprise Linux等系统默认并不安装DHCP服务。

可以使用这个命令来检查系统是否已经安装DHCP服务：rpm –q dhcp如果返回提示“package dhcp is not installed”，说明没有安装DHCP服务。

把CentOS 安装DVD光盘放入光驱，执行以下命令：cd /media/CentOS_5.2_Final/CentOSrpm –ivh dhcp-3.0.5-13.el5.i386.rpm系统会显示安装进度，安装成功后再次执行“rpm –q dhcp”命令，系统会返回消息“dhcp-3.0.5-13.el5”，说明DHCP服务已正确安装。

4)把配置文件模板复制为dhcpd.confDHCP服务的配置要靠编辑/etc/dhcpd.conf来进行。

DHCP服务程序默认没有建立dhcpd.conf 配置文件，但自带配置模板，只要稍加修改就可以使用。

执行“cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf”命令，可以把系统自带的配置文件模板复制到/etc目录并重命名为dhcpd.conf。

(2) 配置 Switch B # 全局使能 IGMP Snooping。
# 创建 VLAN 1024，把端口 GigabitEthernet1/0/1 添加到该 VLAN 中，并在该 VLAN 内使能 IGMP Snooping。

1 组播VLAN典型配置举例
1.1 简介
本章介绍了使用组播 VLAN 功能减轻三层设备负担的典型配置案例。组播 VLAN 有两种方式的典型组网： (1) 基于子 VLAN 的组播 VLAN：IGMP Snooping 在用户子 VLAN 中对成员端口进行维护，适用
环境不限。 (2) 基于端口的组播 VLAN：IGMP Snooping 在组播 VLAN 中对成员端口进行维护，适用于组播
1.3.2 组网需求
如图 1 所示，某二层用户网络通过Switch A与PIM-DM域内的IGMP查询器Router A相连，以接收组播源Source发送的组播数据报文，用户网络内的每个VLAN中都有相同组播组的接收者（Receiver）。现要求通过在靠近三层组播路由器的交换机 Switch A 上配置基于子 VLAN 的组播 VLAN 功能，实现边缘三层组播路由器仅向组播 VLAN 分发组播数据报文，而用户网络内不同 VLAN 内的接收者都可以接收到该报文的目的，从而节省了三层网络边界带宽，也减轻了边缘三层组播路由器的负担。
