SM Session Uptime

I am looking for how to determine the SM session uptime with an SNMP command to the SM.

I have looked and have not found anything.  Anyone know?

Hello hci,

Try: smSessionTimer (.1.3.6.1.4.1.161.19.3.2.2.36), which yields
the amount of time the SM-in-question has been in session with its AP.

Thanks Rajesh.

Best regards, Neil.
