MIBS
The syntax of the MIB description file can formally be specified as follows:
file := tree | tree file
tree := head elements ’)’
entry := head ’:’ index STRING elements ’)’
leaf := head TYPE STRING ACCESS ’)’
column := head TYPE ACCESS ’)’
head := ’(’ INT STRING
elements := EMPTY | elements element
element := tree | leaf
index := TYPE | index TYPE
TYPE specifies a SNMP data type and may be one of
- NULL
- INTEGER
- INTEGER32 (same as INTEGER)
- UNSIGNED32 (same as GAUGE)
- OCTETSTRING
- IPADDRESS
- OID
- TIMETICKS
- COUNTER
- GAUGE
- COUNTER64
ACCESS specifies the accessibility of the MIB variable (which operation can be performed) and is one of
INT is a decimal integer and STRING is any string starting with a letter or underscore and consisting of letters, digits and underscores, that is not one of the keywords.
