SNMP can be used to obtain some basic statistics of the status of the Allegro Network Multimeter.
SNMP support can be enabled in the menu "Settings -> Remote access & export -> SNMP".
Configuration settings
| Configuration value | Available options | Notes |
|---|---|---|
| Enabled | off on for SNMPv1 support |
In firmware < 3.0 |
| SNMP service | disabled SNMPv1 SNMPv3 |
In firmware >= 3.0 |
| User name | The SNMPv3 user name | In firmware >= 3.0 |
| User password | The SNMPv3 password for authentication and encryption | In firmware >= 3.0 |
| Authentication method | SHA SHA-256 SHA-512 |
In firmware >= 3.0 |
| Encryption method | AES | In firmware >= 3.0 |
In case of SNMPv1, the community used is "public".
Supported attributes
- hostname (1.3.6.1.2.1.1.5)
- uptime (1.3.6.1.2.1.25.1.1)
- interfaces (1.3.6.1.2.1.2)
Supported transport methods
The SNMP access uses UDP on port 161. If SNMPv3 is enabled, it uses the User-Based Security Model (USM) for authentication and ecryption. In this mode, only "authPriv" is supported.
| SNMP version | Protocol and port | Security |
|---|---|---|
| v1 | UDP 161 | none |
| v3 | UDP 161 | USM authPriv |
| Feature set | SNMP v1 | SNMP v3 |
|---|---|---|
| plain access | yes | no |
| authentication | no | mandatory (SHA, SHA-256, SHA-512) |
| encryption | no | mandatory (AES) |
| USM | no | yes |
| via TLS | no | no |
| via DTLS | no | no |
| via SSH | no | no |
