variables

Format of variable names

The MIB file serves as a design document when developing an SNMP agent providing information and helps coordinate client and server understanding about what management information represents.

OIDs

Numeric OIDs

Full OID path

Combining the name and numeric subidentifier

Module-qualified OIDs

Object name

This format can be obtained with -Os.

UCD-format

If an OID was passed to the UCD library that did not begin with a dot (and wasn't in the module::name format), then the same prefix was prepended. The example OID from the formats listed above would therefore be given or displayed as
system.sysDescr
The inconsistent handling of OIDs, depending on their location within the OID tree, this format is no longer recommended.

The previous behaviour can be obtained by giving -Ou (for displaying output), or -Iu (for interpreting input OIDs without a leading dot) to most Net-SNMP commands.
