# Configuring existing SNMP Agents

If you installed OneSpan Authentication Server on a host where an existing SNMP service is running and want to use system monitoring in OneSpan Authentication Server, then you will have to configure the existing SNMP agent.

You need to:

- Configure the OneSpan Authentication Server SNMP subagent
- Integrate the OneSpan Authentication Server MIB files

## Configuring OneSpan Authentication Server as SNMP subagent

### Net-SNMP

If you are using Net-SNMP, you can adapt the configuration by editing the respective configuration files.

Add the following lines to the configuration file for the Net-SNMP SNMP agent, i.e. Net-SNMP_install_dir/etc/snmp/snmpd.conf:

```custom
agentaddress ip_address:161
sysObjectID 1.3.6.1.4.1.3995.2.2.1
proc identikey 1 1
master agentx
agentXSocket tcp:localhost:705
```

If agentaddress is not already configured, set ip_address to the IP address of the Net-SNMP agent host.

For more information about SNMPv3 user account management, refer to [http://www.net-snmp.org/docs/README.snmpv3.html](http://www.net-snmp.org/docs/README.snmpv3.html).

### Generic SNMP setup

For information about configuring OneSpan Authentication Server as SNMP subagent for SNMP agents other than the supported versions of Net-SNMP, refer to the documentation for your SNMP manager.

## Configuring SNMP agents to include the OneSpan Authentication Server MIB files

The data for SNMP is held in a Management Information Base (MIB) and can be configured. The configuration file for SNMP applications, i.e. snmp.conf, contains information about the OneSpan MIB files used in OneSpan Authentication Server, which supports a number of MIB modules (also referred to as MIBs).

The MIB files are located in install_dir/mibs.

For more information about the MIBs, refer to the OneSpan Authentication Server Administrator Guide.

### Net-SNMP

If you are using a supported version of Net-SNMP, you can adapt the configuration by editing the respective configuration files.

Add the following lines to the configuration file for the Net-SNMP applications, i.e. Net-SNMP_install_dir/etc/snmp/snmp.conf:

```custom
mibdirs +/opt/vasco/ias/mibs
mibs +VASCO-MIB
mibs +VASCO-IDENTIKEY-MIB
mibs +VASCO-IDENTIKEY-COMMUNICATOR-SEAL-MIB
mibs +VASCO-IDENTIKEY-COMMUNICATOR-SOAP-MIB
mibs +VASCO-IDENTIKEY-CRYPTO-MIB
mibs +VASCO-IDENTIKEY-DATAMODEL-MIB
mibs +VASCO-IDENTIKEY-SCENARIO-MIB
mibs +RADIUS-AUTH-SERVER-MIB
mibs +RADIUS-AUTH-CLIENT-MIB
```

### Generic SNMP setup

For information about installing MIB modules for SNMP agents other than the supported versions of Net-SNMP, refer to the documentation for your SNMP manager.
