Hi Paul
Firstly, I've changed the IP helper-address on VLAN 50 as the IP for the DHCP Server - 10.0.1.14
'Undistributed IPs' is an allocation of IPs not distributed automatically via DHCP (shouldn't really matter but thought I'd add this just in case it did).
As suggested (I hope) following are the relevant named ports etc..
Default VLAN#1
pt#31-32 DC Server / DHCP Server
pt#41 Zone Director (VLAN#50) tagged
pt#45-46 Switches (other layer 2 switches with APs connected all on Default VLAN #1)
ip default-gateway: 10.0.1.4
ip routing: enabled
DHCP-Relay: Enabled
Option 82: Enabled
Response Validation: Enabled
Option 82 handle policy: append validate
Remote ID: mac
vlan #1
name "Default_vlan"
untagged #1-48
ip address 10.0.1.35 255.255.255.0
vlan #50
name "WLAN"
ip address 10.0.50.2 255.255.255.0
ip helper-address 10.0.1.14 (DHCP Server address)
tagged #41
The single NIC on the DHCP server has been configured with the 10.0.50.1 IP in the advanced settings
DHCP Zone (10.0.50.01-254), is active with the Scope Options set the same as the primary zone (i.e. 003 Router 10.0.1.4, 006 DNS Servers 10.0.1.14, 015 DNS Domain Name xxxxx.xxxx).
Zone Director's SSID that I'm testing is configured for VLAN #50. I have another SSID group that uses the default vlan #1 (which retrieves an IP without issue).
That is all the relevant information I can see.
Hopefully there is enough here to pinpoint what I've got wrong, I'm guessing the issue is to do with way I have set the DHCP relay?
Again I appreciate your patience and time Paul.. I have learnt quite a bit since starting this exercise.
