华为交换机DHCPsnooping配置教程
华为交换机DHCP snooping配置教程DHCP Snooping是一种DHCP平安特性,在配置DHCP Snooping各平安功能之前需首先使能DHCP Snooping功能。
使能DHCP Snooping功能的顺序是先使能全局下的DHCP Snooping功能,再使能接口或VLAN下的DHCP Snooping功能。
图1配置DHCP Snooping根本功能组网图如上图1所示,Switch_1是二层接入设备,将用户PC的DHCP请求转发给DHCP 效劳器。
以Switch_1为例,在使能DHCP Snooping功能时需要注意:使能DHCP Snooping功能之前,必须已使用命令dhcp enable使能了设备的DHCP功能。
全局使能DHCP Snooping功能后,还需要在连接用户的接口〔如图中的接口if1、if2和if3〕或其所属VLAN〔如图中的VLAN 10〕使能DHCP Snooping功能。
当存在多个用户PC属于同一个VLAN时,为了简化配置,可以在这个VLAN 使能DHCP Snooping功能。
请在二层网络中的接入设备或第一个DHCP Relay上执行以下步骤。
1、使能DHCP Snooping功能[Huawei]dhcp snooping enable ?ipv4DHCPv4 Snoopingipv6DHCPv6 Snoopingvlan Virtual LAN<cr>或[Huawei]dhcp snooping over-vpls enable#使能设备在VPLS网络中的DHCP Snooping功能或[Huawei-vlan2]dhcp snooping enable[Huawei-GigabitEthernet0/0/3]dhcp snooping enable2、配置接口信任状态[Huawei-GigabitEthernet0/0/2]dhcp snooping trusted或[Huawei-vlan3]dhcp snooping trusted interface GigabitEthernet 0/0/63、去使能DHCP Snooping用户位置迁移功能在移动应用场景中,假设某一用户由接口A上线后,切换到接口B重新上线,用户将发送DHCP Discover报文申请IP地址。
华为路由交换配置DHCP及DHCP中继
DHCP协ቤተ መጻሕፍቲ ባይዱ系统组成
DHCP Client
DHCP Client通过DHCP协议来获得网络配置参数 通常是一台主机或网络设备
DHCP Server
DHCP Server提供网络设置参数给DHCP Client 通常是一台服务器或网络设备
DHCP Relay
在DHCP Client和DHCP Server之间跨网段转发DHCP消息 通常是网络设备
由DHCP Client向DHCP Server提出配置申请,DHCP Server根据策略返回相应配置信息。
DHCP报文采用UDP进行封装,识别采用端口号
DHCP Client使用68,DHCP Server使用67。
DHCP协议特点
整个配置过程自动实现,DHCP Client端无需配置 所有配置信息由DHCP Server统一管理 通过IP地址租期管理,提高IP地址的使用效率 采用广播实现报文交互,报文一般不能跨网段,如 果需跨网段,需要使用DHCP Relay技术实现
Manual Allocation
网络管理员为某些少数特定的主机绑定固定IP地址,且 地址不会过期
DHCP协议分配地址的优先级
DHCP Server数据库中与该DHCP Client的MAC地址静 态绑定的IP地址 该DHCP Client曾经使用过的地址 顺序查找DHCP地址池中可供分配的IP地址,最先找到的 可用IP地址,优先级高 如果未找到可用的IP地址,则依次查询超过租期、发生冲 突的IP地址 找不到则报告错误

华为交换机5700&2700的VLAN、DHCP、ACL配置
拓扑说明:比较简单的三层环境,防火墙进来后接三层交换机s5700,然后接的几台二层交换机s2700,本文只对几个主要的应用配置做个描述1.vlan、gvrp相关配置举例:三层交换机:[5700]vlan 11 创建VLAN11[5700-vlan11]description xxx 加入描述信息xxx[5700-vlan11]quit[5700]gvrp 要用gvrp的话,全局模式下必须开启gvrp [5700]interface g0/0/23 进入与2层交换机连接的端口准备配置中继[5700-GigabitEthernet0/0/23]gvrp 中继端口下开启gvrp[5700-GigabitEthernet0/0/23]port link-type trunk 端口类型设置为trunk[5700-GigabitEthernet0/0/23]port trunk allow-pass vlan all 设置允许通过的vlan为所有,也可设为指定的vlan[5700-GigabitEthernet0/0/23]quit二层交换机:发现华为上不能批量进入端口,只有通过先创建端口组,再把响应端口加入组的方式来实现批量管理,比如我们要在2700上把千兆口都设为trunk口:[2700]port-group trunk 创建名为turnk的端口组,也可取其他名字。
如果已有此名,则会直接进入此端口组[2700-1-port-group-trunk]group-member g0/0/1 to g0/0/4 宣告组成员为G0/0/1到G0/0/4[2700-1-port-group-trunk]port link-type trunk 此组设为中继,即G0/0/1到G0/0/4都为中继[2700-1-port-group-trunk]port trunk allow-pass vlan all 这几步都和三层的配置一样,不同的是我们这里是进行的批量配置[2700-1-port-group-trunk]gvrp[2700-1-port-group-trunk]quit下面把相应端口加入vlan,这里我觉得端口组以vlan命名较为合适[2700]port group vlan11[2700-1-port-group- vlan11]group-member e0/0/1 to e0/0/4 [2700-1-port-group- vlan11]port link-type access 端口设置为access口[2700-1-port-group- vlan11]port default vlan 11 把E0/0/1-4口加入vlan11[2700-1-port-group- vlan11]quit以上VLAN的配置基本完成。

华为交换机配置DHCP中继
华为交换机配置DHCP中继
很多情况下我们需要在三层交换机上配置一下DHCP中继服务;
用以为下面的客户机提供DHCP中继服务;
就是说三层交换机上可以为DHCP端口转发数据到指定的DHCP服务器上;而不会因为是跨VLAN就导致客户机获取不到DHCP分配的IP地址;
方法/步骤
请先确保你的电脑和华为交换机连接成功
进入管理视图
<Quidway> system-view
接着dhcp enable 开启交换机的DHCP服务
接着进入虚拟vlan 视图
[Quidway]interface Vlanif 100
配置一个IP地址
[Quidway-Vlanif100] ip address 192.168.104.253 255.255.255.0
然后开始dhcp中继功能
[Quidway-Vlanif100]dhcp select relay
配置DHCP服务器IP地址
[Quidway-Vlanif100]ip relay address 10.10.100.171
到此华为交换机的DHCP中继功能就配置完成了
记得要save保存配置。

华为路由器DHCP中继配置实例
华为路由器DHCP中继(DHCP Relay)配置实例路由器配置实例早期的DHCP协议只适用于DHCP客户端和服务器处于同一个网段内的情况,不能跨网段。
因此,为进行动态主机配置,需要在每个网段置一个DHCP服务器,这显然是很不经济的。
DHCP 中继(DHCP Relay)功能的引入解决了这一难题:客户端可以通过DHCP中继与其他网段的DHCP服务器通信,最终取得合法的IP地址。
这样,多个网段的DHCP客户端可以使用同一个DHCP服务器,既节省了成本,又便于进行集中管理。
一般来说,DHCP中继既可以是主机,也可以是路由器,只要在设备上启动DHCP中继代理的服务程序即可。
DHCP Relay工作原理如下:1、当DHCP Client启动并进行DHCP初始化时,它会在本地网络广播配置请求报文。
2、如果本地网络存在DHCP Server,则可以直接进行DHCP配置,不需要DHCP Relay。
3、如果本地网络没有DHCP Server,则与本地网络相连的具有DHCP Relay功能的网络设备收到该广播报文后,将进行适当处理并转发给指定的其它网络上的DHCP Server。
4、DHCP Server根据DHCP Client提供的信息进行相应的配置,并通过DHCP Relay将配置信息发送给DHCP Client,完成对DHCP Client的动态配置。
事实上,从开始配置到最终完成配置,可能存在多次这样的交互过程。
下面为大家介绍一个在华为路由器上实现DHCP中继的配置实例。
一、组网需求如下图,DHCP客户端所在的网段为10.100.0.0/16,而DHCP服务器所在的网段为202.40.0.0/16。
需要通过带DHCP中继功能的路由设备中继DHCP报文,使得DHCP客户端可以从DHCP服务器上申请到IP地址等相关配置信息。
DHCP服务器应当配置一个10.100.0.0/16网段的IP地址池,DNS服务器地址为10.100.1.2/16,NetBIOS服务器地址10.100.1.3/16,出口网关地址10.100.1.4,并且DHCP 服务器上应当配置有到10.100.0.0/16网段的路由。
华为DHCP relay(中继)配置教程
华为DHCP relay(中继)配置教程如果DHCP客户端和DHCP服务器不在同一网段内,需要DHCP中继负责DHCP服务器与DHCP客户端之间的DHCP报文转发,这样可以避免在每个网段部署DHCP服务器,节约成本,方便管理。
DHCP服务器和DHCP客户端之间的DHCP报文中继次数不能超过16次,否则DHCP报文将被丢弃。
设备作为DHCP中继时,如果使能了STP功能,可能会造成地址分配较慢。
STP功能缺省处于使能状态,如果确认不需要使能STP功能,可以执行命令undo stp enable去使能STP功能。
当DHCP客户端与DHCP服务器经过三层设备相连时(不在同一网段),需要DHCP中继设备在中间担当一个代理角色,负责转发DHCP客户端与DHCP 服务器之间的通信。
DHCP中继必须与DHCP客户端所在网段直连,但不一定要与DHCP服务器所在网段直连,但要与DHCP服务器所在网段路由通畅。
DHCP中继模式仅可工作在三层模式的接口,DHCP中继设备必须使能DHCP功能1、使能DHCP功能[Huawei]dhcp en2、配置DHCP中继的轮询功能[Huawei]ip relay address cycle仅当dhcp中继设备向多个DHCP服务器转发报文时才需要配置。
当配置多个DHCP服务器后,DHCP中继默认向所有服务器转发DHCP discover报文,会加重中继设备负担。
使能该功能后,中继设备只会选择一个DHCP服务器转发,如果这个服务器没响应,再向另一个转发。
3、配置中继接口的IP地址[Huawei-GigabitEthernet0/0/2]ip address 10.1.1.2 24IP地址必须为DHCP地址池配置的网关地址;中继接口必须为与客户端在同一网段4、启动接口的DHCP中继功能[Huawei-GigabitEthernet0/0/1]dhcp select relay子接口工作在DHCP中继模式时,需要在子接口上配置arp broadcast enable命令,使能终结子接口的ARP广播功能。

【描述】ip relay protocol udp 命令用来配置透传转发协议及其使用的端口号,undoip relay protocol udp 命令用来取消透传转发协议及其端口号。
对于DHCP 中继来说,IP 辅助地址指定的是DHCP 服务器的地址。
配置辅助IP 地址后,从该接口上收到的广播报文,会发送到该服务器上去。
能够配置IP 辅助地址的接口应当支持广播方式。
每个接口最多可配置20 个辅助地址。

[SwitchA]interface Vlan-interface 10
4. 为VLAN接口10配置IP地址
[SwitchA-Vlan-interface10]ip address 10.1.1.1 255.255.255.0
5. 在VLAN接口10上选择接口方式分配IP地址
【补充说明】
也可以在全局配置模式下,使能某个或某些VLAN接口上的DHCP中继功能,例如:[SwitchA]dhcp select relay interface Vlan-interface 10
3,DHCP Snooping
『配置环境参数』
1. DHCP Server连接在交换机SwitchA的G1/1端口,属于vlan10,IP地址为10.10.1.253/24
[SwitchA-Vlan-interface10]ip address 10.1.1.1 255.255.255.0
5. 在VLAN接口10上选择全局地址池方式分配IP地址
[SwitchA-Vlan-interface10]dhcp select global
6. 创建全局地址池,并命名为”vlan10”
利用全局地址池方式,可以完成为用户分配与三层交换机本身VLAN接口地址不同网段的IP地址。

随着通信业的发展以及国民经济信息化的推进,网络交换机市场呈稳步上升态势。
下面是给大家整理的一些有关华为s3700交换机DHCP配置命令,希望对大家有帮助!华为s3700交换机DHCP配置命令1.0快速浏览开启DHCP服务后,必须在接口下配置dhcp select global或者dhcp select interfaceS3700 支持DHCP 服务器,DHCP客户端和DHCP 中继的功能。
其中DHCP服务器可基于全局地支持,也可以基于VLANIF接口的地址。
1.1同网段内配置基于全局地址池的DHCP 服务器示例某公司有两个处于同一网络内的办公室,为了节省网络资源,两个办公室内的PC 机由一台交换机作为服务器统一分配IP 地址。
如图所示,SwitchA 应用为DHCP 服务器,SwitchB 和SwitchC 为用户接入交换机。
可在SwitchA 上配置基于全局的地址池和接口的地址池,下面以全局地址池为例配置SwitchA 为同一网段中的客户端动态分配IP地址。
地址池网段10.1.1.0/24 分为两个网段:10.1.1.0/25 和10.1.1.128/25。
DHCP 服务器两个VLANIF 接口的IP 地址分别为10.1.1.1/25 和10.1.1.129/25。
网段10.1.1.0/25 内的PC 机数量比较少且位置比较固定,地址租用期限配置为10 天,DNS 地址为10.1.1.2,无NetBIOS 地址,出口网关地址为10.1.1.126。
