Hello rcjuan,

here the easiest way:

Get a Mib Browser, like this Link and install them.

Get the DOCS-MIBS. There ara available by the docsis-tool at this site.

Start the Mib-Browser, load the Mib, e.g. DOCS-IF-EXT and make a Get-Subtree to the Cable-IP-Address.

Now, you should got many informations from the cablemodem via SNMP and you can choice which you will use.

Postscript: Natureally, the SNMP-Communty must be right or you use SNMPv1.

Have fun.

Could you be more specific,

Could you be more specific, in which brand and model of CMTS do you need to do that?

For example at HOME you can do like this:
snmpwalk -v 2c -c public IPofCMTS 1.3.6.1.4.1.20858.10.18.1.1.1.2

What it does is list the IP of the cable modems, if it occupies more information other OIDS would need

You will need the snmp oid's

You will need the snmp oid's for each element. status, tx, rx, t3 etc then you query them individually. Some of them the oid is the hex representation of the IP of the modem so it's a bit complicated.

What are you looking for specifically?
