Hi All,
I am attempting to create a DHCP server on the ICX 7850 switch to provide service for a few VLANs that are also defined on the same switch. I have configured the DHCP Server and pool for VLAN 1030. But, when I connect a client device on a untagged VLAN 1030 port (1/1/44), it does not get an IP address. Below is a configuration snippet:
vlan 1030 name Data by port
tagged ethe 1/1/48
untagged ethe 1/1/44
!
interface ve 1030
ip address 10.250.30.1 255.255.255.0
ip ospf area 0
!
ip dhcp-client disable
!
ip dhcp-server enable
ip dhcp-server pool 1
network 10.250.30.0 255.255.255.0
lease-count 253
excluded-address 10.250.30.1
lease 1 0 0
option routers 10.250.30.1
option domain-name-servers 8.8.8.8 8.8.4.4
Any thoughts?

Hi ehuston18,
Thank you for posting you query !!!
I understand that DHCP Server not providing IPs to clients on local VLANs/VEs
>Can you collect a packet capture on the client while trying to get an ip address via dhcp? By doing this we could verify where the DHCP packet is being dropped.
>Have you tested other ports on the same unit to see if they experience the same issue?
>Do any other clients in that vlan receives the ip address successfully?
Please feel free to leave us a message if any concerns
Thanks
