8.1. Usage Example​

For example, consider the encoding of a GetRequest-PDU:

GetRequest-PDU ::= SEQUENCE {
    request-id      Integer32,
    error-status    INTEGER,
    error-index     INTEGER,
    variable-bindings VarBindList
}

Assuming the following values:

  • request-id = 608172092 (hexadecimal 0x24410F3C)
  • error-status = 0
  • error-index = 0
  • variable-bindings = a list containing one VarBind for sysUpTime.0 with an unspecified value

The encoding would appear as follows (in hexadecimal):

30 26           ; SEQUENCE, 38 octets
   02 04 24 41 0F 3C   ; INTEGER request-id
   02 01 00            ; INTEGER error-status
   02 01 00            ; INTEGER error-index
   30 18               ; SEQUENCE variable-bindings, 24 octets
      30 16            ; SEQUENCE VarBind, 22 octets
         06 08 2B 06 01 02 01 01 03 00    ; OBJECT IDENTIFIER 1.3.6.1.2.1.1.3.0
         05 00         ; NULL (unspecified value)

This encoding is then placed in an SNMP message and transmitted using the appropriate transport mapping.
