        Template for monitoring TrueNAS CORE by SNMP.
        
        Setup:
        1. Import the template into Zabbix.
        2. Enable SNMP daemon at Services in TrueNAS CORE web interface: https://www.truenas.com/docs/core/uireference/services/snmpscreen/
        3. Link the template to the host.

For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth. For a sub-layer which has no concept of bandwidth, this object should be zero.
