ICX7150 - configure a vlan to get dhcp from specific dhcp server

[DrBobGulick]

Very new to this so any guidance and grace is appreciated.

Mixed environment with different makes / models of switches leading back to server rack where we have our WIndows DHCP servers. Normally each building has a default VLAN where untagged VLAN for the 'normal' ports on the switch for the building get to DHCP and get a building VLAN IP Address.

We now are installing a clock/pa system within the building and it needs its own separate VLAN. The clock/pa VLAN is on all of the switches between DHCP server and the ICX7150 in question.

From the ICX7150 CLI I can ping the DHCP server, I can ping the clock/pa gateway IP address, we have the ports being used for the clock/pa devices set to the clock/pa vlan as untagged and no tagged vlans. The clock/pa devices are configured for dhcp. When the devices are plugged into the port they do not get a DHCP assigned IP address.

What am I missing here?
