SNMP MIB Data type - equivalent to Erlang "atom" ?

[Serge Aleynikov]

Though it is beyond the scope of this mailing list, here is a sample MIB 
definition containing an integer enum:

balanceMethod OBJECT-TYPE
         SYNTAX INTEGER
                 {
                 random(0),
                 roundRobin(1),
                 leastTime(2)
                 }
         MAX-ACCESS read-write
         STATUS current
         DESCRIPTION
                 "Back-end server balancing method"
         ::= { drpProxyObjects 17 }
