Hello,

I have the following topology:

[R4]------[CAT1]----trunk----[CAT2]----SVI (vlan 30)

R4 is a dhcp server in vlan 30, connected to CAT1 f0/4.
CAT2 has an SVI for vlan 30, with ip address assigned via dhcp.
This works great.

Now when I set up dhcp snooping on CAT1 it fails. On CAT1 I do the
following:

ip dhcp snooping
ip dhcp snooping vlan 30
int f0/4
 ip dhcp snooping trust

This still prevents CAT2 from getting an IP address from R4....is there
something I am missing?
