Ubr7246vxr w/ MC28U not forwarding provisioning requests

Hi,

I have a UBR7246 VXR and two MC28U cards. I have the modems ranging and my provisioning server does not see the requests coming from the modems. I am unsure what I have wrong. Any help would be great. This is my first time configuring a UBR. Here is a sample of my config.

interface Cable5/0
no ip address
no cable packet-cache
cable bundle 1
cable downstream channel-id 120
cable downstream annex B
cable downstream modulation 64qam
cable downstream interleave-depth 32
cable downstream frequency 387000000
no cable downstream rf-shutdown
cable downstream rf-power 61
cable upstream max-ports 4
cable upstream 0 connector 0
cable upstream 0 frequency 20000000
cable upstream 0 docsis-mode tdma-atdma
cable upstream 0 channel-width 3200000 3200000
cable upstream 0 minislot-size 2
cable upstream 0 power-level -1
cable upstream 0 range-backoff 3 6
cable upstream 0 modulation-profile 141
cable upstream 0 equalization-coefficient
cable upstream 0 load-balance group 1
no cable upstream 0 shutdown

interface Bundle1
ip address 172.16.10.1 255.255.255.0 secondary
ip address 10.0.0.1 255.255.255.0
cable arp filter request-send 3 2
cable arp filter reply-accept 3 2
cable source-verify
cable dhcp-giaddr policy strict
cable helper-address 10.10.10.2

Ive been scratching my head on this one. Let me know if you guys have any suggestions.

you need a cable helper

you need a cable helper-address defined on your bundle

i.e.
interface bundle 1
cable helper-address xxx.xxx.xxx.xxx

where xxx.xxx.xxx.xxx is the ip of your dhcp server.

kwesibrunee
most likely you need to add a

most likely you need to add a cable helper-address to your bundle

interface bundle 1
cable helper-address xxx.xxx.xxx.xxx

this tells the cmts where to send dhcp requests from cable modems.

You need a cable helper-address on your bundle interface

i.e.

int bundle 1
cable helper-address xxx.xxx.xxx.xxx

this tells cmts to forward dhcp requests to the helper address.

Have to looked at the IP

Have you looked at the IP helper/Cable helper setting?

IP helper address is in there. This is what I have for the bundle.

interface Bundle1
ip address 172.16.10.1 255.255.255.0 secondary
ip address 10.0.0.1 255.255.255.0
cable arp filter request-send 3 2
cable arp filter reply-accept 3 2
cable source-verify
cable dhcp-giaddr policy strict
cable helper-address 10.10.10.2

It is a remote server that does dhcp and has tftp installed. Should I be doing dhcp locally on the UBr?

Can you post the output of

Can you post the output of command "show run int bundle1"

Would need to see the

Would need to see the configuration for bundle 1 as well.

Like the other poster said, need to look at the helper settings.
