Resolution

The OBJECT IDENTIFIER type is described in RFC 2578 Section 7.1.3. Its instances represent administratively assigned names. Note that both the SMI and the SNMP protocol limit instances of this type to 128 sub-identifiers and require that each sub-identifier be within the range 0 to 4294967295 inclusive.
