Cisco 2960x IP SLA udp-jitter latency not working

Hi,

 

I've setup an 867 router to use as the source in order to collect stats on our WAN performance. All the responders will be 2960x switches running 15.2(2)E

 

Config for the responder is:

ip sla responder udp-echo ipaddress x.x.x.x port 5000

ip sla responder tcp-connect ipaddress x.x.x.x port 5001

 

The source config is:

ip sla 10

udp-jitter x.x.x.x 5000 codec G711ulaw codec-size 240

tos 184

freq 60

ip sla schedule 10 life forever start-time now

 

ip sla 11

tcp-connect x.x.x.x 5001

freq 60

ip sla schedule 11 life forever start-time now

 

I'm getting stats for the RTT, jitter, loss and MoS but latency is showing as samples: 0 with no stats.

 

All network devices are configured with NTP from the same source and set to milliseconds rather than micro.

 

Am I missing some config or is latency not supported on the 2960x devices?

 

Thanks.

Have just setup a responder on another switch and that one works ok:

 

2960x  15.2(2)E               No latency stats.

2960x  15.0(2a)Ex5          Latency stats ok.
