how would an ISP determine what type of cable modem is connected to the CATV? they can allow certain types and deny others? just curious. thanks!

By using the MAC addr of the CM the ISP could not only determine what type modem you are using (assuming you've not changed your MAC) but allow or disallow and place QOS based on this value. Example:
UBR#show cable modem
Interface Prim Online Timing Rec QoS CPE IP address MAC address
Sid State Offset Power
Cable2/0/U0 2 online 2290 -0.25 6 1 10.1.1.25 0050.7366.2223
Hope this helps you,

thanks for the info. but can they allow service based on a particular model of a ubr router? for example allow a ubr925 but disallow a ubr924? somehow this is what is happening. and i'm curious how. it must be up higher then the mac, would this be threw SNMP? also what do they use to change your router configuration? and add ACLS, etc? also SNMP? thanks for the help!
