Overview
Network Device Monitoring helps you gain insights into the health and performance of your on-prem routers, switches, and firewalls.
For additional definitions and descriptions of important NDM terms such as layer 2 and layer 3, see the main Glossary.
Terminology
- Simple network management protocol (SNMP)
- A network protocol that is used to collect information about bare metal networking gear.
- Object identifier (OID)
- A unique ID or address on a device that when polled returns the response code of that value. For example, OIDs are CPU or device fan speed.
- System object identifier (sysOID)
- A specific address that defines the device type. All devices have a unique ID that defines it. For example, the Meraki base sysOID is
1.3.6.1.4.1.29671. - Managed information base (MIB)
- A database or list of all the possible OIDs and their definitions that are related to the MIB. For example, the
IF-MIB (interface MIB) contains all the OIDs for descriptive information about a device’s interface. - Profiles
- A profile is a collection of OIDs associated with a device. Profiles allow NDM to reuse metric definitions across several device types or instances.
- Software-defined wide area network (SD-WAN)
- A wide area network (WAN) that uses software-defined networking (SDN). SD-WAN is often used to interconnect remote offices and data centers across different transports (MPLS, broadband, 5G, and so on).
- Device namespaces
- Namespace of the device. Namespaces can be used as tags to differentiate between multiple network devices that may share the same private IP.
- Ping
- A network tool that measures how long it takes for a signal to travel from one device to another over a network and back again.
