DHCP Snooping between Cisco and HP Switches

Hello,

I am trying to set DHCP snooping in a network of cisco and hp procurve switches

All switches is connected via 802.1q trunk interfaces,

Lots of VLANS defined                  

Default VLAN changed to 199

Static-IP clients works, but DHCP clients cannot obtain IP adress

Is there any special consideration for this case?

Example of Cisco Sw config:

ip dhcp snooping vlan 1-99

ip dhcp snooping

interface GigabitEthernet4/1

switchport trunk native vlan 199

switchport mode trunk

ip dhcp snooping trust

Example of HP Sw config:

vlan 1

   name "DEFAULT_VLAN"

   untagged A1-A4,B1-B24,E1-E4,F1-F24,G1-G4,H1-H24

   exit

vlan 2

   no ip address

   tagged A2

   exit

dhcp-snooping

dhcp-snooping authorized-server 10.0.71.74

dhcp-snooping vlan 1

interface A2

   dhcp-snooping trust

   exit
