 Technically, there is no standard variable that contains the enterprise ID
of the device.  When it comes to SNMP, a device might actually support
a number of MIBs from a number of vendors.

Most times, a vendor of a specific device may place something into their
sysObjectID that can be used to identify the device type, but it is not
limited
(or restricted) to containing their enterprise # as part of it.

 For example:

If it uses Net-SNMP on Linux, (by default) it provides
.1.3.6.1.4.1.8072.3.2.10.

However if you query the devices _I_ manufacture you will see something
like: 1.3.6.1.4.1.1978.5.7

Correct.  If you see the value you are interested in, inside the
sysObjectID,
it is your requirement/responsibility to extract it (from wherever you find
it).
