Internet Speed Testing

[Alex Pfeil]

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.

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.

[Alex Pfeil]

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.

[Joseph W. Doherty]

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
