OID for Registered SM Count on an AP

Hey everyone, back in 2007 Jerry Richardson replied to apost and mentioned using SNMP to monitor the registered SM count on an AP - http://motorola.motowi4solutions.com/support/community/viewtopic.php?f=1&t=4326
I have been looking but can’t find the OID for the registered SM count. Can anyone help me out? I’ll keep browsing too.

Thanks again in advance…

Figures I would find it right after I posted this…

Type Integer
Desc: Number of registered Sms.
