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
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
