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-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.
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.
Anyone have any suggestions?
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 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 command "show run int bundle1"
Would need to see the configuration for bundle 1 as well.
Like the other poster said, need to look at the helper settings.
error on interface bundle 1 configuration.
