Labnario Huawei From Scratch

Huawei, to meet your expectations, recently announced the launch of an enterprise network simulation platform eNSP for ICT practitioners. This information you can find at official Huawei website.

To be honest, I have not tested it yet. If I find time I will do it this week. I have already installed this simulator on my notebook and it looks promising. We can build a network based on AR1200 routers and enterprise switches.

The only think you have to do is to register at Huawei website, download and install the simulator.

I forgot to mention that this simulator is completely for free.

To make it easy for you, below you can find a direct link to the Huawei eNSP:

Please feedback your comments if you test it. I would like to know your opinion.

Enjoy!

Sometimes we can meet such situation on a router or a switch:

By default, on Huawei device, there are 5 vty lines available. If all these lines are occupied by users, no other user is able to access the device. Such situation can appear in 2 cases:

1. The device is fully occupied by telnet users.
2. All telnet sessions are hang.

The first case is normal and it can often happen. Sessions will be deleted when users log out from the device or their sessions’ idle-timeout expires. By default idle-timeout is set to 10 minutes.

Maybe it should have been shown at the beginning of this blog…

As you probably know, Huawei datacom devices are divided in 2 segments: Telco and Enterprise. But what you decide to choose depends on you. You do decide which device you want to use, regardless of it is intended for telco or enterprise. You know the best which device is appropriate for your network. Having detailed technical specification you are able to choose the device which meets your requirements.

For those who don’t know where to find information about Huawei’s portfolio, I am sending direct links to proper pages:

I decided to spend my vacation without access to internet, only wife, children, beach and windsurfing. I succeeded, September 3rd was the first day, after 3 weeks of my vacation, when I opened my mail box. Sorry for the delay in replying for your emails.

Last time I was asked about a procedure how to upload files through console port. The procedure is simple and I will try to show it in this post. Taking Huawei’s S3300 switch as an example I will show you how to upload file through console port, upgrading bootrom at the same time. Notice that uploading files by console is very slow and it is better to use it only for small files, unless you do not have any other choice.

Please use HyperTerminal to upload files by console port.

Power on the switch and enter into bootrom mode by pressing CTRL+B (default password huawei):
