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)
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 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?
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?
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
I have this weird issue with one of my MC-88V line cards. The cmts is a uBR7246VXR with 12.2(33)SCG3. I'm not doing anything too fancy, just 4x2 bonded channels per MAC domain. Anyhow here is the problem. On one downstream(C4/1) we have 1 rf-channel that will not come up, the other 3 are up and working fine(42dB SNR). It will start to initialize for a while then go to disabled(DOCSIS LB group). First I though something was stomping on that freq(705) but the spectrum analyzer showed otherwise, no noise or anything when I shut the channel down to check the noise floor.
Has anyone done a package with upstream speeds at 25megs or 45megs, and if so, how are your upstreams and cm configs set up? I've got 2 bonded 64qam 6.4mhz wide upstreams, and I'm finding it more difficult to get the upstreams to actually run at the provisioned speeds, more than 18mbs. I can get it closer by setting the SfMaxTrafficBurst up higher, but that surely I don't want that number to be ridiculously high?
