Cisco 3560 not working with smaller HP switches

Dear Experts,

 I need to know why the new Cisco switch 3560 is not working with a HP 1400-sg Procurve switch.

It is not allowing IP traffic dynamic (DHCP) or static (IP).  

Is there a limit on the mac addresses I need to know about?

The HP is an unmanaged switch with 8000 entries in MAC address table, so we have a managed switch linking to an unmanaged.
The Cisco should have port to HP set up as an access-port (in relevant vlan)

Are you able to post scrubbed configs for both switches?

By chance do you have any type of DHCP snooping enabled? Do the vlan tags (or lack thereof) match on the link between the switches?
^yeah post configs so we can have a look see.

If its unmanaged you have what i call a dump switch not far off a hub.
The only traffic it will push through will be native so if you was the devices connected to it to receive IP addresses for vlan 100 you would need to have vlan 100 the native vlan on the port connecting to it
