Could anyone help me with which MIB, and value I need to use to get the software version number for an ASA OS and the ASDM?

Hi Stephen.

I doubt you could "trap" it, but you may be able to poll the ENTITY-MIB if you are running SW version 7.0 or later on the ASA.  Please see the following document of the supported MIBs in the ASA:

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_tech_note09186a0080094a13.shtml#mibsupportbyversion

As mentioned, I suspect the ENTITY-MIB is what you'll need to poll, and specificly this object:

.1.3.6.1.2.1.47.1.1.1.1.10
entPhysicalSoftwareRev OBJECT-TYPE
     -- FROM     ENTITY-MIB
     -- TEXTUAL CONVENTION SnmpAdminString
     SYNTAX          OCTET STRING (0..255)
     DISPLAY-HINT     "255a"
     MAX-ACCESS     read-only
     STATUS          Current
     DESCRIPTION    "The vendor-specific software revision string for the
            physical entity.

            Note that if revision information is stored internally in a
            non-printable (e.g., binary) format, then the agent must
            convert such information to a printable format, in an
            implementation-specific manner.

            If no specific software programs are associated with the
            physical component, or this information is unknown to the
            agent, then this object will contain a zero-length string."
::= { iso(1) org(3) dod(6) internet(1) mgmt(2) mib-2(1) entityMIB(47) entityMIBObjects(1) entityPhysical(1) entPhysicalTable(1) entPhysicalEntry(1) 10 }

Good Luck!
