I have a PC and DHCP server each plugged into a 3550 switch. They are on vlan 13, server on fa0/14, PC on fa0/1.
I enable DHCP snooping on vlan 13 in global config mode. When I plug in the PC to get an address, it gets the address. I thought the switch was supposed to block DHCP packets on untrusted ports? Am I mistaken?
Next I enabled the server port as "trusted". I use a different NIC on the PC to plug in....I got an IP address but it did not show up in the binding database...
Am I missing something on how this is supposed to work?
