Docsis chat

Hi,

I wonder if someone can tell me if this is possible using dhcpd.conf and a mainstream CMTS...

I have a standard cable modem setup running with trialists provisioned via dhcpd.conf. That works well.

Now, I'd like all clients (PC's) that are connecting via a specified cable modem to be treated differently. (I'd like those clients to get a different range of IP addresses and DNS info, and be redirected to a "login" server for authentication).

So, is it possible within dhcpd.conf to identify these clients (based on the mac address of their modem) and treat them differently?

A friend has a Cuda CMTS and docsis server at a operator.

The DHCP is allways getting Ip address requests and the server is allways sending DHCP Offers but not getting an ACK from the cpe.

Any tips ?

Thank you in advance.

I have
dhcp-authority enable
cable cpe max-ip to 4
dhcp-policy 1 permit xxxxxxx agent-option cm
dhcp-policy 2 permit xxxxxxxxx agent-option cpe
dhcp-policy default permit forward-internal
dhcp-authority enable
dhcp-relay add-agent-options enable relay-mode append
dhcp-relay server xxxxxxxxxx

proxy arp is also enabled.

The company from Poland has a few efficient ARRIS CMTS 1500 for sale.

HI, does anyone know how to identify wich upstream a cable modem is.
thank you

or anyone knows to make a summary of the cable modems

I have configured a secondary scope to handle our increased growth. I'm utilizing CNR ver7.0 and since I have created this secondary scope the dhcp server hands out the routers option from the primary scope. For example:

Primary scope 192.168.1.0/24

GW: 192.168.1.1

Secondary Scope: 192.168.2.0/24

GW: 192.168.2.1

When a customer obtains an IP from secondary scope (192.168.2.2 for example) their GW address is 192.168.1.1.

On the CNR server I have the secondary scope configured to use the Attribute "Primary Subnet" of the primary scope (ex: 192.168.1.0/24). Any suggestions?
