The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).

Efficient way to get backups off site to Azure

This user guide provides instructions on how to deploy and configure both a StoneFly Scale Out NAS Enterprise Cloud Drive virtual machine and Veeam Cloud Connect in the Microsoft Azure Cloud.

Sometimes you have to pull out old tricks to get a new firewall to work…

While we were installing a new Sonicwall at a customers site we found that sites they were able to visit before were not working.  It seemed random and we could not understand what was happening.  Everything in the Sonicwall was checked and rechecked to no avail.  Then it dawned on me!  Looking at the WAN connection, I saw the dreaded “PPoE”.  It’s been a long time since I’ve worked with a PPoE circuit.  In fact I was surprised to see it.  I thought they all died…

Anyway, I had to into the archives of my brain (boy it sure is dusty in here) and remember how to figure out the proper MTU to set on the WAN interface to get this going.

For those of you wondering what an MTU is, it is a Maximum Transmission Unit.  Basically a cap on the size of your Ethernet packets.  Normal Ethernet packets have an MTU of 1500.  PPoE doesn’t like that 1500 and it is almost always to big.  So we have to reduce the packet size so communications can work effectively.

First we have to determine the MTU, this is easily done with the ping command:

    ping <sitename> to see if you get a response.  You should always get a response even if you MTU is not correct because ping will allow fragmentation of packets.  I usually use google.com since it always responds.
    Next we have to force the ping command to use a certain packet size.  This is done using the /f and /l switches. /f will set the “Don’t Fragment” flag in…

Cable Modem Provisioning from DPoE compliant server

 This Article is to support CMTS administrators to provide an overview of DOCSIS compliance configuration file, and to provision a cable modem located at customer place from a Back office server.

CMTS administrators used to get stuck up in resetting or offline state for their cable modem (ONU) during the provisioning process, even though the MAC address has been detected by the CMTS. This Article will help them to check the steps before start debugging it.

This document consists of below 6 sections.
DOCSIS configuration files editor.
Incognito Management console.
Association of configuration template.
Creating Configuration Template.
Associating ONU with .cfg file.
Enable ONU Provisioning.

1.      DOCSIS configuration files editor:

This is a Cable labs proprietary tool, GUI based configuration editor running on Windows PC, used to configure VLAN id, upstream, downstream related parameters/QoS Parameters. These parameters are defined by the Service provider based on the Service package purchased by the customer. You need Cable labs configuration file editor to try the following steps.

In a new File editor window, look for the GEI parameter [43][28]. To configure our ONU as E-line “L2VPN identifier” should be configured as EPL-2
If the ONU is connected using UNI port 1, CMIM value should be configured with the hex value equivalent to 40 00 00 00

This solves the problem of diagnosing why an internet connection is no longer working. It also helps identify the likely cause of the lost connection if the procedure fails to re-establish your internet connection. It helps to pinpoint the likely component or service that needs further attention, be it the Router, Cable/DSL Modem or issues with your (I)nternet (S)ervice (P)rovider.

To save time, this issue is frequently caused by a computer and Modem that are not communicating.  One quick step may resolve the issue without going through all the troubleshooting below.  Turn off your computers.  Remove all electrical power from the ISP Modem for 30 seconds.  Re-power the Modem and let it cycle for about 1 to 2 minutes.  If the Modem LED's do not indicate a connection to the internet, you should call your ISP Tech Support.  If your Modem LED's appear normal, restart the computer and try to connect.  If you still cannot connect, try the 10 steps below.  (Note: If you are getting any kind of Pop-up Messages regarding Virus, Malware or Spyware on your system, this will not help you.  Your connection is being hijacked by Malicious software and you need to address the issues of Malware Removal.)

  Over the past few years, small business and home owners have become so dependent on internet that a need for redundancy has arisen.

   What happens when your small business or home / home office loses its internet connection?  The results can be devastating if you rely on the internet connection for phone service, security systems or even customer support.   It’s expensive to have two different service providers at your location and in some cases it’s not even an option. This is why many people have began using cellular devices for that redundancy.  It’s not perfect but it fits the need quite nicely.
 Here are some steps used to make decisions on needs VS wants.

Select you cellular service

 Make sure the cellular company and device you select will work in your area. No provider is better than another in every area.  Do your research and make sure you do not get stuck in a contract without connectivity in your area.  You can rent a device for a few weeks and make sure it’s well supported in your area.

  The best service can be obtained from dedicated device such as a USB or PCMCIA / Express device.  You can do it with data enabled cell phones but drivers and batteries can become an issue.  Also in off hours if the office or home does not need it you can use it for travel and after hours use.

  Once you select a device pick a plan.  If this is a rare occasion you might want to go with a ‘pay as you  use’ or a pre pay device.  If you want to use it …

Since I don't have one, I looked for the VLAN capabilities for the RV082.   I didn't find anything...  Is there a reference you might point to?

Thanks!

look at page 35.  You can create up to 8 vlans and assign them to the specific ports
