我使用了华为的三层 二层交换机,配置接口VLAN,并做了IPSG功能,可是发现有一些客户PC,DHCP获取到了IP,却不能进入内网,咨询华为,升级到高级别,老师查询日志后,三层 二层,配置均没有错误 ,vlanif dhcp,也做了网关排除,反馈说,一些MAC地址,获取到了 AP所在vlan的网关地址,我查询到这些MAC,全部都是H3C WA2220E-AG 的MAC,再向华为确定,回复说,这些AP获取到了所在VLAN的网关地址。有哪位大神知道这是什么情况?

华为三层的arp
以上找到了这些MAC,和IP,知道都是 H3C WA2220E-AG
下以是其中一台的配置
接口WEB配置:
组网情况是:
华为的三层交换机有多VLAN,做基于接口的DHCP服务器,------------二层有多VLAN做IPSG 静态和动态------二层交换机其中一个接口--------普通交换机---------------H3C WA2220E-AG(默认VLANIF1)配置静态VLAN的IP 例如 VLAN 109 的IP 192.168.109.57)

从华为的日志这里看到有终端的IP冲突了。先解决下IP冲突的问题再测试下业务看看。根据MAC找到终端修改写IP。

根据MAC ,找到的IP,就是我第一 二 三 张截图的华三AP配置的静态IP,
您好,因为是手动设置的IP,可能跟其他自动获取IP的终端冲突了。
你好,谢谢你的回答,但是不会的,因为我DHCP 都是X.100以后,手动IP,都是100以内,所以你说的情况可以排除, # interface Vlanif107 ip address 192.168.107.1 255.255.255.0 dhcp select interface dhcp server excluded-ip-address 192.168.107.1 192.168.107.16 dhcp server excluded-ip-address 192.168.107.20 192.168.107.100 dhcp server static-bind ip-address 192.168.107.17 mac-address e86a-644e-fd27 dhcp server static-bind ip-address 192.168.107.19 mac-address e89a-8f5f-33ba dhcp server static-bind ip-address 192.168.107.18 mac-address f875-a477-4fba dhcp server lease day 0 hour 8 minute 0 dhcp server dns-list 192.168.16.152 192.168.16.150 # interface Vlanif108 ip address 192.168.108.1 255.255.255.0 dhcp select interface dhcp server excluded-ip-address 192.168.108.1 192.168.108.150 dhcp server lease day 0 hour 8 minute 0 dhcp server dns-list 202.96.134.133 202.96.128.166 # interface Vlanif109 ip address 192.168.109.1 255.255.255.0 dhcp select interface dhcp server excluded-ip-address 192.168.109.1 192.168.109.150 dhcp server lease day 0 hour 8 minute 0 dhcp server dns-list 192.168.16.152 192.168.16.150
您好,看了配置是没什么问题,但是华为设备这样报,可以咨询下华为工程师进一步分析看看。
华为给的解释是 这个AP 获取了网关,
获取了网关地址作为AP的IP?这样还是会冲突的,但是看到表项是没有冲突的。

跟华为的互联是使用hybrid的方式?
是的,,我有几种 ,一种是华为的二层接口,写hybrid ,直接AP,有一种是华为的二层hybrid 接普通交换机,再接AP,,,还有一种是二层接口hybrid,接AP,AP上有多VLAN 多SSID,。。
