-Both hardware and software-level information about your appliance is available with SNMP v3. Due to the lack of encryption and privacy for the `noAuthNoPriv` and `authNoPriv` security levels, we exclude the `hrSWRun` table (1.3.6.1.2.1.25.4) from the resulting SNMP reports. We include this table if you're using the `authPriv` security level. For more information, see the "[OID reference documentation](http://oidref.com/1.3.6.1.2.1.25.4)."

Several MIBs are available, which you can see by running `snmpwalk` on a separate workstation with SNMP support in your network:
