DHCP from another vlan going to computers

Hi guys,

​

I have a 48 port switch that has port 48 going to a DHCP agent (router) with 3 vlans, 2,10,20. I then have an access point that is directly connected to port 47 and it gets IP from 48. I then have a switch connected to all my computers and a DHCP server on port 1 (vlan 1).

​

Vlan membership is as follows:

​

1: Untagged 1-48

2: forbidden 1-46, tagged 47,48

10: forbidden 1-46, tagged 47,48

20: forbidden 1-46, tagged 47,48

​

For some reason the DHCP server from 48 is taking over and assigning addresses to the computers through port 1.

​

I'm not sure what I'm missing here? Any help would be appreciated!
