三层漫游后终端获取不到IP地址
问题描述：
用户正常接入可以获取IP地址，三层漫游后终端获取不到IP地址，要等很久能可以获取到。本地转发，AC、DHCP 配置均无问题，是什么原因导致的 ？
组网及组网描述：
AC：WX3510H AP：4320-ACN AC旁挂在思科核心上，DHCP在思科核心上。

如果只是拿地址
百分之99问题在交换机上，查查交换机有没有创建和放通vlan
(0)
本地转发三层漫游时，从A区域漫游到B区域后发现AP上会自动创建A区域的vlan，在AC上查看client 发现vlan信息还是A区域的，那么我的接入交换机需要创建A区域的vlan信息？
zzzzzz 发表时间：漫游对于AC而言就是保证vlan不变，对于上线过的用户，AC会默认保持vlan信息180s，所以本地转发就必须要保证交换机将业务vlan放过去（集中只要管理vlan就行）。如果sta跑到其他区域需要vlan改变，那种就不是纯粹的漫游，最多叫重新接入
王老二 发表时间：但是我遇到sta跑到其他区域后AP上会自动生成之前区域的vlan信息，这个是什么机制呢 ？sta跑到其他区域后仍然使用之前区域的vlan信息导致用户获取不到IP地址。
zzzzzz 发表时间：这个就是漫游的机制啊（各个厂家不太一样），保持原来的地址信息不变。有一条命令client cache aging-time 可以控制，配置成0就是不继承原先的vlan信息
王老二 发表时间：
三层漫游，漫游过程中地址应该是不会变化的，如果重新获取地址了，那不叫漫游了吧

三层漫游IP地址不变？
zzzzzz 发表时间：三层漫游是开启mac-vlan的，漫游的整个过程地址都是不变的啊。
哈哈 发表时间：这很难讲诶 有配置贴出来看看嘛

配置就是正常配置做的本地转发，DHCP在思科核心上。正常接入都没问题，三层漫游就获取不到IP地址

回复xxx [x] 已采纳 知了小白 粉丝：人 关注：人我也遇到这个问题，只要开启快速漫游，三层漫游过去会获取不到ip，苹果变169开头的ip上不了网，关闭快速漫游后就正常，会带vlan和ip漫游到新ap，开启快速漫游关闭vlan保持，同样正常，只不过会连接新ap就获取一次地址。
