Disable CPE user

Hello,

I have a question that can be banned from allocating IP addresses of CPE, options MAXCPE 0; does not work, right there are other options?

Thanks.

Stopping CPE traffic

I am guessing that you want the modem to stop any CPE traffic
You must set the Network Access Control to off or '0' depending upon your config file editor

A little confused by what you want to do, but it sounds like you want MTAs to be able to use the modem but not any other CPEs i.e. something connected to the ethernet or usb ports?

If this is the case yes it is possible but modem manufacturer specific

in your config file you can set .1.3.6.1.2.1.2.2.1.7 ie. ifAdminStatus to integer 2 (down)

for arris modems this is:

ifAdminStatus.5 down // USB aka .1.3.6.1.2.1.2.2.1.7.5 = 2
ifAdminStatus.1 down // ethernet aka .1.3.6.1.2.1.2.2.1.7.1 = 2

this disables the ethernet and usb ports when the modem boots but allows the MTA to continue working normally, we use this for customers that only take our voice service.

if you don't know what the snmp index is of the ethernet or usb ports you could always snmpwalk the modem and look for it.

Hello,
Thanks for the information. I am using Motorola SBV5121E modem. I do not want to turn off etherent and USB port, but I want him banned from the IP address assigned by your docsis server, but we want to allow the possibility of connection via a PPPoE.

Hello,

Unfortunately I have not managed to solve your problem, so please help.
For provisionoing CMTS modem, using docsis server sw. I have to solve this urgent problem, so please help.

Means that over the config file can exclude IP addresses assigned to users (DHCP), not to turn off line into the USB port? Users will use PPPoE.

Thanks.

downing the interface(s)[1]

downing the interface(s)[1] doesnt work, maxcpe = 0 blocks the voice side coming online and i believe violates the spec

what we have done is this

Set the default ip filter to discard, this doesnt deactivate the ethernet port (youll get a connection light) but nothing will transfer through it.

Option 11 .iso.org.dod.internet.mgmt.mib-2.docsDev.docsDevMIBObjects.docsDevFilter.docsDevFilterIpDefault.0,INTEGER,discard

On our modems the emta is connected internally on interface '16. You then enable traffic on that interface as below.

Sorry for the non docsis.sf.net format data. But i believe you can see the approach

[1] modems with usb ports tend to have the ethernet on a different interface to the usb ethernet. walk the modem, see if thats the case. it was on our SA emta's

Downing the Interfaces

Downing the Interfaces should be 2 not 1 (this is up) which is probably why it did not work for you, the filters you list essentially are the same thing but in multiple lines

be careful with max-cpe = 0 cuz on some modems (read Motorola some older firmwares)that means unlimited rather than none.

I have had great success with Arris Voice modems using the interface down method, never tried it on SA modems so your mileage may vary
