Hi, I have an IP SLA jitter process configured on my router. See config below. I have discovered the SLA Process via SNMP using a 3rd party SNMP product but I need to know the OID I should query to collect the Jitter and Mos Figures. RTT Latency seems to work fine but I am having problems with Jitter /MOS. The config looks fine, sla output looks okay but my snmp manager still doesn't display any stats for Jitter/MOS.
I'm running c2800nm-entservicesk9-mz.124-7a.bin on my router. Config and output below from show ip sla monitor stats/config is attached.
I know the RTTMON mib is involved but when I browsed the mib on cisco's website, I was a bit overwhelmed. The OID 126.96.36.199.188.8.131.52.42.1.3 but after that I appear to have 7 other sub-values..
Config is as follows:- ip sla monitor 1 type jitter dest-ipaddr 10.80.100.54 dest-port 16384 codec g729a codec-size 30 tos 160 verify-data owner fpm frequency 15 ip sla monitor schedule 1 life forever start-time now
