Network simulator software

[jhill000111111111]

I'm looking for a good network simulator software to build a physical network virtually that also supports the commands used on the physical network. Thank you in advance.

James - GNS3 is very popular among networking community. A lot of people use it for certification studies or POC related testing. It has a little limitation it can't simulate switch ASICs (but has switch modules, which is pretty close)

Google GNS3 or GNS3 getting started you will get a lot of stuff on how to set it up and use.

Hi all,

How to distinguish a software simulator from a hardware one? 

Just one tac engineer writes to us that he is testing on real hardware. But we think that he is testing on software. How can you tell visually? we want to connect to it via webex

Hi there,

Ask to see the output from 'sh inv', that will show an 'empty' chassis if it is running virtually.

cheers,

Seb.

Hi there,

I would personally recommend using EVE-NG for a virtual lab. I started my network career using GNS3 but encountered problems saving configs with later versions that made the switch to EVE-NG and have never looked back.

To be honest both suites use the same virtualisation backends, so it is very much about GUI preference and easy of configuration rather than raw performance. That said you tend to see the larger labs running on EVE-NG.

cheers,

Seb.

Hello
Sad to say but I would suggest eve-ng , I moved on to this last year from cisco virl and its a excellent piece of simulation software.
It is able to support Cisco’s vril images and other vendors too, Also its dockers are excellent Cisco virl doesn’t provide either of these.
