What version are you running? The snmpd.conf(5) manual page in 
5.2.2.pre3 documents the following settings:

- ---snip ---
engineID STRING
   The snmpd agent needs to be configured with a unique engineID to
   be able to respond to SNMPv3 messages.  With this  configuration
   file line, the engineID will be configured from STRING.

engineIDType 1|2|3
   Defines  that the engineID should be built from the IPv4 address
   (1), IPv6 address (2) or MAC address (3). Beware that you  might
   run into trouble on IP address changes!

engineIDNic interface
    Defines  the  interface  (e.g.  "eth1")  that  should be used to
    determine the MAC address in case of "engineIDType  3".  Default
    is eth0.

If  neither  an  engineID,  engineIDType  or  engineIDNic  directive is
present, the value of the engineID is built from 2 fairly  random  ele-
ments:  a  random  number  and the current time in seconds. This is the
recommended approach.

It is automatically written into the persistent configuration file 
(/var/net-snmp/snmpd.conf by default on Un*x) as "oldEngineId <value in 
hex>".
