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?
the switch is running 12.2(25) I believe. I'll get the exact version when I get home this afternoon. the client port is always untrusted in my lab, i just toggle the server port between trusted and untrusted.
I'm not sure about option 82 - I'll do a capture and post the results. Not sure where that comes in to play so I will have to do some more research.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
