I enabled DHCP snooping on the VLANs and uplink interfaces, and everything was working.  I plugged in a new device today to a switch and that device is not getting dhcp.  The port the device is connected to is untrusted.  I also cleared the dhcp snooping table.  Any ideas why the new device is not getting dhcp?

 

The device is connected to an ip phone.  The phone gets the right VLAN dhcp, and it works, but not the pc connected to the back of the phone.  I double checked everything and it looks correct.

I also tried adding the device under the static binding configuration, but I still can't ping the new device

    Another thing I'm worried about is that, most of the people are working remote now.  But what happens when they return, and they don't get dhcp?
