# Embr-SNMP (BETA) > # Stability Warning > > This module is still in beta, and therefore breaking configuration changes may occur between now and the final release. Use at your own risk. This thread is for discussion related to Musson Industrial's Embr-SNMP module. Embr-SNMP provides a set of OPC UA device drivers for SNMPv1, SNMPv2c, and SNMPv3. ## Usage - Install the module. - Add your devices under `OPC UA/Device Connections`. - Point your tags at the OPC UA device using the OID as the Node ID. ## Example (reading `sysName`) `ns=1;s=[MyDevice]1.3.6.1.2.1.1.5.0 ` ## Known Issues ### Write Support Write support is extremely basic; all writes occur as strings šŸ¤·ā€ā™‚ļø. * * * ## Downloads ~~[Embr-SNMP-Ignition81-0.1.0.modl](https://forum.inductiveautomation.com/uploads/short-url/4IvpO2A70wndGkilfj8o9SbFFWr.modl) (2.3 MB)~~ ~~[Embr-SNMP-Ignition81-0.2.0.modl](https://forum.inductiveautomation.com/uploads/short-url/xDrUCeGebuX7xBheNVT0TCxyYnh.modl) (2.3 MB)~~ [Embr-SNMP-Ignition81-0.2.1.modl](https://forum.inductiveautomation.com/uploads/short-url/ntGFUgqcoHcyq9eQSNegTJHcWNs.modl) (2.3 MB) [Embr-SNMP-Ignition83-0.2.0.modl](https://forum.inductiveautomation.com/uploads/short-url/94LbTeD9s0tJNrPsL7RGjk1b4QY.modl) (2.3 MB) Any feedback related to SNMPv3 usage would be greatly appreciated. ---

Just installed this one, went straight to the V3 and configured a Mikrotik router as the SNMP host. System immediately connected and tags came up. This was with SHA-1 and AES-128 on a private community. Nice work. When is the code going on GitHub? šŸ˜ƒ ---

Just the string containing the address including the colons, I have a feeling there could be a typical parsing error where the colon gets assumed to denote a port mumber. ---

I tried with both the same username and different usernames, also the same auth and priv encryption as well as different. It also seems to not reset something, so if I delete the second connection, the first still stays disconnected. All I get is no response logs, even with TRACE level. ---

Funky, the USM is probably all kinds of messed up. This seems relevant, saving for later: > **[Multiple SNMP agents (v1.7.6a)](https://forum.snmp.app/t/multiple-snmp-agents-v1-7-6a/1287)** > > Hello, First I have to mention I have to use SNMP4J version 1.7.6a for specific reasons. In our application, we have to deal with 2 different SNMP v3 agents, each with a specific security name / auth/priv. When setting up only one or the other,... Looks like we should be using a shared global `Snmp` object instead of creating one for each device. ---

I have a feeling this is actually an issue because docker doesn't have IPv6 support enabled by default. Also IPv6 addresses should work if added in the host field as: `[xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx]` ---

Upload MIB files to the gateway, and then you can use either symbolic names or OIDs. On tag creation or update, a symbolic name can be converted to the corresponding OID in the tag provider backend. Adding to this, the MIBs could be used to translate the browsable OIDs that match from the initial browse. Add scripting functions into the module for manual event triggers. ---
