IP SLA jitter output

Unanswered Question


I've a setup with two 2800's on two datacenter and I want to see the jitter from one datacenter to the other. So I've configured an IP SLA and an responder but the output I get gives me only RTT and no jitter measurements. I've checked CCO and they say you get '0' when the devices are not timesynced. But I am sure they are in sync with each other.

Here is my config:

ip sla monitor 1

type jitter dest-ipaddr x.x.x.x dest-port 5000

request-data-size 64

tos 5

ip sla monitor schedule 1 life forever start-time now

on the other router:

ip sla monitor responder

ip sla monitor responder type udpEcho port 5000

Any ideas?
