How is NETIF\_SNMP\_ACCESS supposed to work with NetObserv Flow? Where can I find documentation for the file format and options?

I set the following but never see any SNMP queries from the collector:

```auto
EF_PROCESSOR_ENRICH_NETIF_SNMP_ACCESS_ENABLE: "true"
EF_PROCESSOR_ENRICH_NETIF_SNMP_ACCESS_PATH: /etc/elastiflow/settings/snmp_access.yml
EF_PROCESSOR_ENRICH_NETIF_SNMP_ACCESS_REFRESH_RATE: 15

```

/etc/elastiflow/settings/snmp\_access.yml contains:

```auto
10.0.0.1:
    enabled: true
    port: 161
    retries: 2
    timeout: 5
    version: 3
    v3_credential:
      username: 'mysnmpusername'
      authentication_protocol: 'sha'
      authentication_passphrase: 'secret_passphrase'
      privacy_protocol: 'aes'
      privacy_passphrase: 'privacy_passphrase'

```

If I configure the section below then SNMP queries work but I have multiple devices with different SNMPv3 credentials which is one of the reasons I want to use the “ACCESS” method.

This works but only for hosts which share SNMP settings:

```auto
EF_PROCESSOR_ENRICH_NETIF_SNMP_COMMUNITIES: snmpusername
EF_PROCESSOR_ENRICH_NETIF_SNMP_ENABLE: "true"
EF_PROCESSOR_ENRICH_NETIF_SNMP_PORT: 161
EF_PROCESSOR_ENRICH_NETIF_SNMP_RETRIES: 2
EF_PROCESSOR_ENRICH_NETIF_SNMP_TIMEOUT: 5
EF_PROCESSOR_ENRICH_NETIF_SNMP_V3_AUTHENTICATION_PASSPHRASE: "secret_authphrase"
EF_PROCESSOR_ENRICH_NETIF_SNMP_V3_AUTHENTICATION_PROTOCOL: SHA
EF_PROCESSOR_ENRICH_NETIF_SNMP_V3_PRIVACY_PASSPHRASE: "secret_passphrase"
EF_PROCESSOR_ENRICH_NETIF_SNMP_V3_PRIVACY_PROTOCOL: AES
EF_PROCESSOR_ENRICH_NETIF_SNMP_V3_USERNAME: "snmpusername"
EF_PROCESSOR_ENRICH_NETIF_SNMP_VERSION: 3

```

The default snmp\_access.yml contains some examples. Please note that this is YAML format, so indents/spacing must follow specific rules. It’s hard to tell from the text you show above if your snmp\_access.yml is formatted properly. Here are the examples from the default file that shows the proper formatting in a code block.

```auto
# default:
# enabled: true
# port: 161
# version: 1
# community: 'sith'
# retries: 1
# timeout: 2

# 192.0.2.1:
# poll_ip: 192.0.2.251
# port: 6161
# version: 1
# community: 'jedi'

# 192.0.2.10-192.0.2.19:
# retries: 2
# timeout: 3

# 192.0.2.201:
# enabled: false

# 192.0.2.128/26:
# version: 3
# v3_credential:
# username: 'darth_vader'
# authentication_protocol: 'noauth'
# privacy_protocol: 'nopriv'

The post took all the spacing out. Let’s try again.  
The default snmp\_access.yml file was appended with:

```auto
10.0.0.1:
    enabled: true
    port: 161
    retries: 2
    timeout: 5
    version: 3
    v3_credential:
      username: 'mysnmpusername'
      authentication_protocol: 'sha'
      authentication_passphrase: 'hidden'
      privacy_protocol: 'aes'
      privacy_passphrase: 'hidden'

```

The examples do not include **authentication\_passphrase** or **privacy\_passphrase** so I am making an assumption that they are supported parameters. Maybe that’s part of my problem but if so how should they be defined?
