# Enumerations

Enumeration allow for integer and OID values to be translated to their text values.

The location of the enumeration definition files is specified by `EF_PROCESSOR_SNMP_ENUM_DEFINITIONS_DIRECTORY_PATH` in the collectors configuration options. The default location is `/etc/elastiflow/snmp/enums`. Enumeration lookups must also be enabled by setting `EF_PROCESSOR_SNMP_ENUM_ENABLE` to `true`.

### Bitmap Enumerations

Bitmap enumerations are evaluated when the attribute `syntax` is `EnumBitmap`.

EXAMPLE:

```yaml
# mplsTunnelCRLDPResFlags
.1.3.6.1.2.1.10.166.3.2.10.1.5:
  0: 'PDR' # PDR
  1: 'PBS' # PBS
  2: 'CDR' # CDR
  3: 'CBS' # CBS
  4: 'EBS' # EBS
  5: 'weight' # Weight
```

### Integer Enumerations

Integer enumerations are evaluated when the attribute `syntax` is `EnumInteger` or `EnumIntegerKeepID`.

EXAMPLE:

```yaml
#ifOperStatus
.1.3.6.1.2.1.2.2.1.8:
  1: 'up' # up
  2: 'down' # down
  3: 'testing' # testing
  4: 'unknown' # unknown
  5: 'dormant' # dormant
  6: 'not present' # notPresent
  7: 'lower-layer down' # lowerLayerDown
```

### Object Identifier (OID) Enumerations

Object Identifier (OID) enumerations are evaluated when the attribute `syntax` is `EnumObjectIdentifier` or `EnumObjectIdentifierKeepOID`.

EXAMPLE:

```yaml
# hrStorageType - hrStorageTypes
.1.3.6.1.2.1.25.2.1.1: 'other' # hrStorageOther
.1.3.6.1.2.1.25.2.1.2: 'RAM' # hrStorageRam
.1.3.6.1.2.1.25.2.1.3: 'virtual memory' # hrStorageVirtualMemory
.1.3.6.1.2.1.25.2.1.4: 'fixed disk' # hrStorageFixedDisk
.1.3.6.1.2.1.25.2.1.5: 'removable disk' # hrStorageRemovableDisk
.1.3.6.1.2.1.25.2.1.6: 'floppy disk' # hrStorageFloppyDisk
.1.3.6.1.2.1.25.2.1.7: 'compact disc' # hrStorageCompactDisc
.1.3.6.1.2.1.25.2.1.8: 'RAM disk' # hrStorageRamDisk
.1.3.6.1.2.1.25.2.1.9: 'flash memory' # hrStorageFlashMemory
.1.3.6.1.2.1.25.2.1.10: 'network disk' # hrStorageNetworkDisk
```
