We used IP SLA Hub & Spoke to create a VoIP UDP Jitter operation. Hub is Cisco Catalyst 6509-E running 12.2(18)SXF11. Status message for every operation with the 6509 is "Operation setup on the node failed. NO_CREATION". RW SNMP string verified. Feature set of this IOS verified to include IP SLAs - UDP Jitter.
What else is there to check or verify?
