TE offline tools
Hello, I'm curious what is the tools for computing and validating TE tunnels over the network. I read on MPLS Enabled Applications that there are tools out there that can be used to do so. Anyone has a suggestion?

Re: TE offline tools
I'm aware about the Cisco MATE software, but I'd prefer an open-source, vendor-agnostic one, something that in-house imporvements can also be achieved.

Cisco CCNA Training
We have a couple of techs that want to learn cisco and networking in general. What do you recommend for learning and getting certified on Cisco? There seems to be a million different training courses, books, etc out there.
Tail-F
Is anyone using Tail-f software or know anything similar? We are looking for a solution that is vendor agnostic. Can do simple command like show interface so even non-network techs and CSR's can get basic is the port up or down type stats without having to directly login to the network.
Re: Cisco CCNA Training
Depends on how the techs in question learn best, but I've found that a good CCNA book (like the Lammle one) combined with either a network simulator (I like Boson, but packet tracer and GNS3 are both good too) or, better yet, physical hardware they can play with. Alternatively, if you have a local community college nearby that has the Cisco Academy curriculum, that's a great option as well. - http://www.amazon.com/CCNA-Routing-Switching-Study-Guide/dp/1118749618/ref=sr_1_1?ie=UTF8qid=1414949721sr=8-1keywords=lammle+ccna On Sun, Nov 2, 2014 at 9:02 AM, Colton Conor colton.co...@gmail.com wrote: We have a couple of techs that want to learn cisco and networking in general.

Re: Cisco CCNA Training
I have a couple of techs who have done well with the offical cisco books and another couple who have passed using video training from CBT Nuggets. Depends on the user really, it seems the younger folks soak up the video training a bit easier while the more senior techs preferred to read the material.

Re: Industry standard bandwidth guarantee?
Consider a better analogy from the provider side: A customer bakes a nice beautiful fruit cake for their Aunt Eddie in wilds of Saskatchewan. The cake is 10 kg - but they want to make sure it gets to Eddie properly, so they wrap it in foil, then bubble wrap, then put it in a box. They have this 10kg cake and 1kg of packaging to get it to up north. They then go to the ISP store to get it delivered - and are surprised, that to get it there, they have to pay to ship 11kg. But the cake is only 10kg! If they pay to ship 11kg for a 10kg cake, obviously the ISP is trying to screw them. The ISP should deliver the 10kg cake at the 10kg rate and eat the cost of the rest - no matter how many kg the packaging is or how much space they actually have on the delivery truck. And then the customer goes to the Internet to decry the nerve of the ISP for not explaining the concept of packaging up front and in big letters. Why they should tell you - to ship 10kg, buy 11kg up front! Or better yet, they shouldn't calculate the box when weighing for shipping! I should pay for the contents and the wrapping, no matter how much it is, shouldn't even be considered! It's plain robbery. Harrumph. Perhaps that's because in the case of shipping, it is usual and customary to expect an item to be packaged carefully and that the packaging is counted as part of the shipped package. From the provider side (bearing in mind I've been in that business for a few decades), usually what the customer wants is to understand what they're purchasing, and if you as a provider tell them that they're buying a 100Mbps circuit, they kinda expect that they can shovel 100Mbps down that circuit. No amount of but you should expect that there's packaging and you should just /knoow/ (whine added for emphasis) that means only 80Mbps usable is really going to change that. That's why I designed an analogy that is much more representative of reality than yours. ...

Re: Tail-F
Tail-F's ConfD can operate as a front-end CLI and do the things he wants it to do in an operational sense but I would agree it may not be the easiest to use tool for simply monitoring and grabbing interface state/statistics. It's fairly flexible and can do a lot of abstracted things through its ConfD element but there is some backend work to make it happen. Not as much as doing it from scratch but still a bit of work. It can abstract different device CLIs so they all look the same and use the same commands and you can extend the CLI to do custom things as well if you want. The whole system is fairly powerful and very extensibe. There are monitoring elements built into it and It could be a full blown monitoring system, really just depends on the scale you need and how much work you want to put into it.

Re: Tail-F
I am aware that you can see if a port is up or down through SNMP. I guess that was a bad example. I want to see the entire output of a show interface command. For example, we have multiple types of access networks (GPON, DSL, Cisco ethernet switches). Some of the show interface commands are fairly basic, but others like on a DSL port show much more information like sync rate, signal loss, etc. The only way to get this information on some platforms is to run the show interface command for CLI I believe, or login to the access platform's GUI interface. Both of these task aren't so easy when you are dealing with multiple access platforms.

SO you have to find all the OIDs that return the information you want to see. Simple but sometimes very, very tedious. You then wrap your data collection in a application/webpage that displays it. Vendor agnostic. Not turn-key without spending lots and lots and lots of money. Another option: have you tried using Expect?
Re: TE offline tools
You can look at tools like NS2/NS3 or OMNet++, but these are not going to do what you want out of the box, they are a framework for network simulation but you'll have to program them to do what you want, they are more used in academic settings. If you want a nice interface you are kind of stuck right now with the commercial offerings from Cariden, OpNet, WANDL (now Juniper), and Aria Networks. Most of those packages are extensible via scripting if you want to do additional things.

Re: Cisco CCNA Training
Depends on how quickly you want them trained, and how they tend to learn things Reading is good, but can be boring and tedious and not always have all the answers. Standard ILT can be costly, but very quick and often standard (though I¹d shop around for who you have as an instructor since that can make or break the success)! Video-based training gives a good mix of things and there are options out there. I know there¹s been one other response for CBT Nuggets, which I would definitely recommend. Take that with a grain of salt (and I¹m ok with that) since I do some work for them now. However, I would have recommended them even before I started developing training for them. :) Jeremy Cioara teaches the CCNA courses for CBT, and he is quite animated and very knowledgeable. He will definitely get all the necessary points across. In addition to the certification courses you mentioned, there are also many ³real world² variants of materials as well, which give a different slant to the teachings that you may find useful for your group. And being a subscription cost, you can watch as many different things as you¹d like rather than being limited to one course. Something worth checking out. Don¹t take my word for it, go look for yourself (or have your group do that).

Re: Cisco CCNA Training
You might look at your local community college's offerings. Probably better bang for the buck than many other offerings.
