DHCP Snooping - missing command?

I was having a hard time with this awhile ago because I could not get an address even when I enabled "trust" on the server port. However, after looking through the PG on Mock Lab 3 and discussion in the cisco channel on freenode I found out the issue.

I needed this command on the server:

R2(config)#int e0/0
R2(config-if)#ip dhcp relay information trusted

Now my binding database is populated after about 9 months!

SW1#show ip dhcp snooping binding
