Hi
We have 7 HP Procurve Switches around the building, and 1 DHCP windows server 2008.
On server 2008, there are already 8 dhcp scopes. On Switches, there are 8 VLANs pointing back to DHCP server with ip helper-address 10.89.31.6.
Problem is:
On the server 2008 DHCP, I created a new scope:
NEW-WIFI
IP Scope: 10.89.41.5 to 10.89.41.250
subnet mask: 255.255.255.0
Gateway: 10.89.41.1
On the core switch, I created vlan 70:
VLAN 70
name “NEW-WIFI”
ip helper-address 10.89.31.6
ip address 10.89.41.1 255.255.255.0
tagged 44-48
exit
On one of hub switches, I created vlan 70 also:
untagged 40
tagged 45-48
no ip address
Then I plugged a device in, it’s not getting ip address from dhcp.
Where did I do wrong?
Many thanks in advance!

1st step is checking routing
Can server2008 ping the new VLAN interface 10.89.31.6 ?

10.89.31.6 is the windows dc server itself.
From the server, I can ping 10.89.41.1 which is the gateway of the new scope and ip address for new vlan.
But my laptop or WAP just not getting any IP assigned.

Found the problem.
The switch I tested with was not connected to core switch directly. But via another switch in a different hub room.
New VLAN was not setup on that switch, although no port was used.
Had to create vlan on all switches and it is working now.
Cheers
