1760上可以实现不同vlan的不同DHCP地址范围吗

如题！！


网友1：

可以，做两个ip pool就可以


楼主问：
然后如何把 这两个IP pool 映射到各自的VLAN呢？

网友2：
这是在用的3550的原配置：

网友3：

俺想知道如何使各vlan的地址不会混
是因为vlan的原因吗？

网友4：

这个问题，我现在还不是太清楚
在上面的配置中，感觉应该是比如switch发现该端口属于vlan50后，因为配了
interface Vlan50
ip address 192.168.50.1 255.255.255.0
所以switch知道该vlan的ip应该是50段的，所以自动到50段的ip pool
ip dhcp pool *_DXSYB
  network 192.168.50.0 255.255.255.0
  default-router 192.168.50.1
  dns-server 202.101.103.55 202.101.107.55
  lease 8
里面选取一个50.×的ip分配给客户端
纯属推测
不一定准确
