How can I script a ping test to a number of hosts?

Unanswered Question

I would like to test the network links from the perspective of the host's receivers, Windows and Linux boxes. I am looking for an analysis of packet losses.


Is there a good way to test this? Would a ping test do it? Can a ping test be scripted from the router?


There are no errors on the receive ports of the switches, 6513s and 4506s.


By the way, I now believe in cleaning the fiber ends prior to inserting them in ports. I have use optics alcohol cleaning pads, but this is discouraged by Cisco. They also discourage liquid air. They prefer the dry cartriges.


I purchased a Fluke DTX-1800 cable tester. This gives me a pulse of the link quality. I live in the aerospace world.

Secondly there are host of tools comming which can monitor through pings link DUDE and WhatsUP.


Hope that will help.

Thanks for the reply. I don't have the VoIP software SLA though. I couldn't locate DUDE either. We do have WhatsUP but it will present a problem in my case because I can only reach the devices from their default gateways because of firewalls running on these hosts.


There are a couple of new options though. One is tclsh. This stands for Tool control language shell. It is available in IOS 12.3(2)T.

R1#tclsh.


http://blog.sazza.de/?cat=10 This page shows you how to use the command and another command called "macro".


I don't have either capability in my version. So I am still researching.
