Hi. I have the following topology (attached). I have a computer which is connected to a new hp switch 48 port (J9627A model) which I recently configured. After connecting my computer to the hp 9627A switch, I noticed that it was not obtaining an ip address. However, if I swap this hp 9627A switch with another switch the computer gets an ip address, so I know that the dhcp server is working and the problem might be a misconfiguration with the hp 9627A switch.
Below is the output from the show running-config command on the hp 9627A switch:
Running configuration (HP: J9627A):

Am I missing a command which is preventing the switch from forwarding the computers dhcp requests?
Solved! Go to Solution.

Re: HP switch (J9627A) not forwarding dhcp request of computer to dhcp server
What IP address/default GW is on the DHCP server?
What is the config of the other switch?
What does the "ip default-gateway 10.2.0.1" achieve, given this switch doesn't appear to have any interface in that subnet?
Why do you have two routes for 10.2.0.0/24?
What does a default route pointing at a network address (10.3.0.0) even do?
How can a default route point at an IP address (10.2.0.1) that doesn't belong to any local subnet?

Solutionthe default gateway is suppose to be 10.3.0.2 (not 10.2.0.1, that was a mistake), though this change didnt fix the problem. Removing the management-vlan 1 command with "no management-vlan 1" fixed the problem and the computer now gets an ip address from the dhcp server. Am curious as to why the management-vlan 1 command was preventing the switch from forwarding the dhcp requests of the pc.

Re: HP switch (J9627A) not forwarding dhcp request of computer to dhcp server
The "management-vlan" command is basically a security setting. It stops access to the switch from other VLANs and it also stops routing to and from that VLAN. Disabling the management-vlan setting was definitely the right answer.
