I have a router running approx 400 IPSLA operations. The IPSLA results in VNQM are frequently "Unknown", with a message of "Polling job timed out, the source may be busy or down."
The router isnt down, and doesn't seem to be heavily loaded, so I assume it's just a timeout issue.
Where is the timeout set for VNQM polling the results of IPSLA operations? Does it use the system-wide SNMP timeout, or is there another setting?
