I'm working on setting up a cmts lab a cisco ubr7246 and using isc dhcpd 4.1.1 on centos 6.x with some Arris TM602g cable modems and I'm having some trouble with the cable modems acknowledging their dhcp offer and then configuring.

The modems will get a dhcp discover to the dhcpd server and the dhcpd server will do a dhcp offer, but the modem doesn't seem to like the dhcp offer options.

The ubr7246 has the ip address 192.168.0.1 with ip addresses for the CM's and CPE's on a interface bundle with 10.0.0.1 for the CM's and 172.16.0.1 for the CPE's

Hello list,

There is two Cisco CMTS: one 7246, and another 10012.
Cisco 10012 case:
When one modem goes offline, then this CMTS immediately delete the
CPE IP address from the own CPE database. -> this is Bad
(If i run 'show cable modem aaaa.bbbb.cccc' then i see that NumCPE is reset to 0)

Have quantity of new in the box fully licensed Arris C4 32D cards available at up to 80% off MSRP.

Hello all
I have a CMTS 1000 and I have noticed a security vulnerability. If I configure an appropriate ip address statically on a CPE device connected to a authenticated modem I can grab network access. Long story short this is an issue because I want the CPE devices to only get a ip address from the ip pool configured in the dhcpd server.

This may help you understand

Router
Ip address primary 10.0.0.1/24 (Modem Pool)
Ip address secondary 172.16.0.1/24 (CPE Pool)

Anyone have 12.3(23)BC for a 7246VXR G1?

Is the FE1 (ethernet) management port on the back controlled in an "Off"/"On" state through configuration, or is it always "On", illuminating similar to FE0? Further, what does the FE1 ethernet cable ideally connect to? The FE1 port I have doesn't illuminate/blink.

Hello All,

Does anyone have the latest SIP firmware for SBV5121E?

Thanks,

Hello my CMTS: motorola bsr 2000 works fine but the problem is that i need to send telnet command for wake up port:
interface cable 0/0
shut
no shut, every time I restart it or unplug it from power source.

My question is does any idea to setup cmts make startup execute this command?

Best Regards

I was wondering which is the best way to retreive information from a CM whether configuring remote-query or making manual scripts to poll information directly from the CMs.

Does someone know which is the recommended amount of CMs per CMTS you should consider a maximum limit to remote-query for 30 seconds poll intervals?

Any suggestion for modem parameters monitoring?

Thanks in advance

Please answer me this:

Our internet department is telling me that we are needing to swap modems out because of bad ethernet ports on the SB5101 series modems. Is this a common thing with this type of modem?

Please let me know your experience in regards to this
