IP SLA Monitor to Measure QoS Performance for VoIP
I am trying to create 2 IP SLA Monitors, one for measuring jitter/delay for non VoIP traffic and a second one for Measuring Jitter/delay for VoIP traffic, which I am trying to get to use the Access-list for QoS keying off the EF DSCP. The Results should be able to tell me if my QoS implementation is working and if I have enough trasmit bandwidth in my network. The network is basically a DMVPN with the spokes using Broadband Internet access, Cable & DSL.
It appears to me that the IP SLA Monitor is not effected by my QoS Policy, I am traffic shaping to 256K and when I overload the output interface, my QoS policy does not appear to effect my second IP SLA Monitor.
Re: IP SLA Monitor to Measure QoS Performance for VoIP
The only thing I would look out for is a less specific policy in your policy map above the definition of your more specific policy. It's possible that you've got a generic voip traffic list being matched.
Otherwise - it looks fine. You may want to get a packet capture and confirm that IP SLA is building the packet as expected. There may also be an issue with matching locally generated traffic. You could try generating the traffic a hop or two before your QoS policy and see if it changes the output.
