Internet Speed Testing

Is there a replacement for TTCP on the cisco 4000 series routers? I used to be able to complete some throughput tests using ttcp and I am no longer able to do that.  Does anybody have a different solution for testing between two routers or networks through the internet.  We did not want to use a speedtest website.

Re: Internet Speed Testing

You should be able to find stand-alone TTCP and/or other bandwidth test packages. However, those will likely require some other host rather than the router itself.

Yes, I can do the iPerf or jPerf from a computer. I was just looking to see if there is a hidden command like ttcp.

Re: Internet Speed Testing

TTCP is the only hidden command, for bandwidth testing, that I'm aware of. Even then, it's not found in all IOS images.

Hello

You can probe the end-to end connection via ip sla, this would give you a good indication of the RTT of a certain protocol if applicable.

R2

conf t
ip sla responder

R1 -  
ip sla 10

tcp-connect 2.2.2.2 23
timeout 500
frequency 2
   
 or
udp-echo 2.2.2.2  67
frequency 5

     or

icmp-echo 2.2.2.2 source-ip 1.1.1.1
timeout 1000
frequency 5

ip sla schedule 10 life forever start-time now

sh ip sla statistics | be RTT





kind regards
Paul
