华为交换机DHCP基于全局配置和基于端口配置举例-说明.docx

网络拓扑图如下所示：说明：1.交换机Ge0/0/1口和Ge0/0/2口配置基于全局的DHCP；2.交换机Ge0/0/3口配置基于端口的DHCP；3.交换机上配置vlan 10 、vlan 20 、vlan 30。vlan 10 地址，vlan 20地址，vlan 30地址。4.Ge0/0/1属于vlan 10，Ge0/0/2属于vlan 20，Ge0/0/3属于vlan 30。配置：Huaweidis cu#sysname Huawei#vlan batch 10 20 30 “创建VLAN”#cluster enablentdp enablendp enable#drop illegal-mac alarm#dhcp enable “启用DHCP服务”#diffserv domain default#drop-profile default#ip pool vlan10-pool “基于全局配置的DHCP地址池” gateway-list network mask dns-list #ip pool vlan20-pool “基于全局配置的DHCP地址池” gateway-list network mask dns-list 5#aaa authentication-scheme default authorization-scheme default accounting-scheme default domain default domain default_admin local-user admin password simple admin local-user admin service-type http#interface Vlanif1#interface Vlanif10 ip address dhcp select global “设置DHCP基于全局配置”#interface Vlanif20 ip address dhcp select global “设置DHCP基于全局配置”#interface Vlanif30 ip address dhcp select interface “设置DHCP基于端口配置” dhcp server excluded-ip-address 01 54 “排查01到54这些地址” dhcp server dns-list # interface MEth0/0/1#interface GigabitEthernet0/0/1 port link-type access port default vlan 10#interface GigabitEthernet0/0/2 port link-type access port default vlan 20#interface GigabitEthernet0/0/3 port link-type access port default vlan 30#interface GigabitEthernet0/0/4#interface GigabitEthernet0/0/5#interface GigabitEthernet0/0/6#interface GigabitEthernet0/0/7#interface GigabitEthernet0/0/8# interface GigabitEthernet0/0/9#interface GigabitEthernet0/0/10#interface GigabitEthernet0/0/11#interface GigabitEthernet0/0/12#interface GigabitEthernet0/0/13#interface GigabitEthernet0/0/14#interface GigabitEthernet0/0/15#interface GigabitEthernet0/0/16#interface GigabitEthernet0/0/17#interface GigabitEthernet0/0/18#interface GigabitEthernet0/0/19#interface GigabitEthernet0/0/20# interface GigabitEthernet0/0/21#interface GigabitEthernet0/0/22#interface GigabitEthernet0/0/23#interface GigabitEthernet0/0/24#interface NULL0#user-interface con 0user-interface vty 0 4#returnHuawei（说明：上面红色字体部分是基于全局配置的，基于全局配置情况要在全局模式下设置dhcp服务的地址池、dns、网关等；绿色字体部分是基于端口配置的，基于端口配置的部分要在int vlan 30的接口下进行配置dhcp的dns、网关、地址池等。）查看交换机上的arp表：Huaweidis arpIP ADDRESS MAC ADDRESS EXPIRE(M) TYPE INTERFACE VPN-INSTANCE VLAN - 4c1f-ccb7-23ea I - Vlanif1054 5489-98cf-bd73 1 D-0 GE0/0/1 1053 5489-98cf-2650 1 D-0 GE0/0/1 1052 5489-98cf-bd73 1 D-0 GE0/0/1 1051 5489-98cf-2650 1 D-0 GE0/0/1 10 4c1f-ccb7-23ea I - Vlanif2054 5489-98cf-8b50 1 D-0 GE0/0/2 2053 5489-98cf-5c20 1 D-0 GE0/0/2 2052 5489-98cf-8b50 1 D-0 GE0/0/2 2051 5489-98cf-5c20 1 D-0 GE0/0/2 20 4c1f-ccb7-23
