There is no Average two way jitter value but I can get it via SNMP.
SNMP OID is: 184.108.40.206.220.127.116.11.18.104.22.168.1.46 - rttMonLatestJitterOperAvgJitter Avg of Positive and Negative Jitter in SD & DS direction
How does this value calculate? What formula has been used in IOS for this calculation?
I've tried to calculate this value by myself with the method from RFC 3550 and I get different result than IOS gets me via 22.214.171.124.126.96.36.199.188.8.131.52.1.46 OID.
