What got the DHCP to be working are the following commands: IP dhcp snooping vlan 1interface gi0#/0/# ( port the DHCP server is connected to)ip dhcp snooping trust   Then the following commands are also useful for seeing more informationshow ip dhcp snooping interfaces show ip dhcp snooping binding    I am running into another issue though.  To begin with I plugged the receipt printer directly into both switches. I got the receipt printer to work on the test switch. The test switch sees the MAC address, and it is able to authenticate proper for the Radius server. On the live switch though it will get an IP address, but it will never show the port as being up or see the MAC address.
The issue is that DHCP works when the Radius server is disabled, but when it is enabled DHCP does not work. I have gotten this to work on the test network. The test switch and production switch use the same configuration except for the source IP address. The clients do show up in the authentication list, and if they are using a static IP address they do not lose their internet connection.When monitoring this with wireshark it appears that the DHCP packets just never reach the DHCP server when the Radius server is enabled. I was thinking about "IP address-helper" to route all dhcp packets directly to the DHCP server to see if this helps. I was wondering if anyone had ran into this issue or had any insight on this. The configuration file is below.
