how do i setup continuous pings to a device? PT or GN3

i need to do a task using spanning tree

i want to be able to do a task whereby i have spanning tree running and have a device which i can continuously ping, for example the command -t

i will be switching over to rapid spanning tree during the excercise and want to show in real time of how packets dont get dropped when running rapid spanning tree as opposed to normal spanning tree

is this possible using packet tracer or gn3?

thanks

Well if you have a PC hooked into GNS3 you've already answered your own question (ping -t).

If you're talking about running a ping from a cisco device just use the repeat option "ping 1.1.1.1 repeat 100000"

I use three VirtualBox machines - over my old faithful - VirtualPC.
1. First You'll need to download and install virtualbox separately. Do not add a Network adapter. Otherwise, Setup a Xp machine. Themes, wallpapers, sounds... Close the virtualbox to shut it down.

- You may need to restart the computer.
- Make sure you open GNS3 with administrator privledges
2. Open up GNS3, add the Guest by going to Preference > VirtualBox > VirtualBox Guest tab.
3. Select the XP machine under "Identifier Name" Click "Save". It'll add the guest to the name list below.

The just click and drag a VirtualBox Guest from the side. Really, that's it. You don't need to setup NICs inside virtualbox in itself - GNS3 will add the adapter automatically. The most you'll need to do is inside the virtualbox guest, setup it's IP address.

Now the reason I say XP is because it's easy to configure, and it works. I've tried to use Fedora, even after google searching for the commands to do it - i decided to go back to xp. Mostly because im taking my test monday... I'd rather have less time learning non-cisco stuff and more time labbing

Don't need to worry about a firewall with this

Oh and B]ping x.x.x.x -t[/B is to constantly ping. Setup more computers and transfer files across the network - It's sweeter when you go stuff

thanks for the replies

yeah i will ping from another router within gns3 and want to run a constant ping

ive tried the repeat ping command but with that, it displays a '!' rather then 'reply from x.x.x.x blah blah blah' which displays on seperate lines.
i need to be able to view the 'reply from x.x.x.x blah blah blah' rather then '!'

is this possible with just using router ios images within gns3?

thanks
