trying to get DHCP to work on a VLAN but DHCP server is on another VLAN

hi all,

 

i have two vlans and we call it the production vlan

110

130

 

the dhcp server is on vlan 130 (10.110.130.50) and its handing out dhcp leases to vlan 110 and it works on all the other switches as any computer you plug in on an access vlan 110 it gets a 10.110.110.x address

 

but everytime i plug in my laptop to this 4510 cat switch its not working

 

heres my config

 

interface Vlan110
ip address 10.110.110.4 255.255.254.0
ip helper-address 10.110.130.50
!
interface Vlan130
ip address 10.110.130.4 255.255.254.0

 

am i doing something wrong

 

thanks,

rob

if that DHCP Server local you do not need, if that is outside of the switch, yes suggested.

How is your Switch Access port configuration, how this 4510 connected to other switch.

 

can you post the 4510 configuration and explain how this is connected to Uplink Switch ?

ok scrap this it works,

 

i was being a donut as on our dhcp server we have set mac authentication so i needed to put it in the allow filter

 

also do you think i need a dhcp helper address?
