SNMP

[Miroslav Šinko]

RFC1157 doporucuje NULL, ale nezakazuje iny typ.

 Some PDUs are concerned
   only with the name of a variable and not its value (e.g., the
   GetRequest-PDU).  In this case, the value portion of the binding is
   ignored by the protocol entity.  However, the value portion must
   still have valid ASN.1 syntax and encoding.  It is recommended that
   the ASN.1 value NULL be used for the value portion of such bindings.
