SNMP MIB Tree Hierarchy
- SNMP organizes data in a hierarchical tree called the MIB tree.
- This structure allows querying for specific device values efficiently by traversing the tree.
Use SNMP Traps for Alerts
- Configure SNMP devices to send traps for specific events to your monitoring station.
- Use traps as alerts for proactive network management and issue detection.
Avoid SNMP v1, Choose v3
- Avoid using SNMP v1 as it is obsolete and insecure.
- Prefer SNMP v2c or better yet SNMP v3 for network monitoring, with v3 offering improved security.
