Description: Provides network diagnostic objects for ping, traceroute, and connectivity testing via SNMP.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is NETWORK-DIAGS?

NETWORK-DIAGS is a diagnostics MIB that exposes SNMP-triggerable ping and traceroute functionality for active network connectivity testing, conceptually similar to the IETF DISMAN-PING-MIB/DISMAN-TRACEROUTE-MIB. It provides tables for initiating and tracking ping tests (destination, owner, type, action, status) and traceroute tests (destination, owner) directly from the managed device, rather than exposing passive interface or environmental counters. Its use in monitoring device/software status is indirect but useful: it lets an administrator remotely verify network reachability and path health as seen from the device itself, helping distinguish 'device is up but network path is broken' from other fault conditions. It parallels IETF Disman ping/traceroute MIB conventions and typically sits alongside IF-MIB/IP-MIB for addressing context. It is deployed on routers, switches, or other network devices where built-in active-diagnostic capability is useful for remote troubleshooting, making it a common building block of NETWORK-DIAGS SNMP monitoring on those platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETWORK-DIAGS. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

vendor-neutral, standards-derived diagnostic MIB, applicable to routers/switches supporting SNMP-triggered diagnostics

Monitoring Examples

An operator would create an entry in nwIpPingTable/nwIpPingEntry setting nwIpPingDestination, nwIpPingOwner, and nwIpPingType, then set nwIpPingAction to trigger the test and poll nwIpPingStatus for the result. Similarly, nwIpTraceRouteTable/nwIpTraceRouteEntry with nwIpTraceRouteDestination and nwIpTraceRouteOwner would be used to trace the path to a remote host. A ping test returning a failed nwIpPingStatus while the device's own interfaces show up would indicate a downstream network problem rather than a local device fault, and nwRevisionLevel/nwRevision would confirm which diagnostic engine version is running.

What Can Be Monitored

on-demand ping test destination/status
ping test owner/type
on-demand traceroute test destination
traceroute test owner
diagnostic engine revision level

OID symbolic	OID numeric	Type	Access	Description
nwRevision	1.3.6.1.4.1.52.4.1.3.1.1
INT nwRevisionLevel	1.3.6.1.4.1.52.4.1.3.1.1.1	INTEGER	read-only	This shows the current revision level of this mib.
nwInternet	1.3.6.1.4.1.52.4.1.3.1.2
nwIpPing	1.3.6.1.4.1.52.4.1.3.1.2.1
nwIpPingTable	1.3.6.1.4.1.52.4.1.3.1.2.1.1		not-accessible	This table allows outbound ping requests to be generated from the Cabletron device to a specified destination IP address. It is indexed by destination address and source address to allow multiple ping requests by different owner IP addresses.
nwIpPingEntry	1.3.6.1.4.1.52.4.1.3.1.2.1.1.1		not-accessible	An IP Ping Table entry containing objects for a particular ping request.
IP nwIpPingDestination	1.3.6.1.4.1.52.4.1.3.1.2.1.1.1.1	IpAddress	read-write	The IP address of the host/device to be pinged.
IP nwIpPingOwner	1.3.6.1.4.1.52.4.1.3.1.2.1.1.1.2	IpAddress	read-write	The IP address of the client which created this ping request. A value of 0.0.0.0 indicates the request was made from the local console.
INT nwIpPingType	1.3.6.1.4.1.52.4.1.3.1.2.1.1.1.3	INTEGER	read-write	The administrative control of this ping request entry. This leaf is used to create a ping request entry.
INT nwIpPingAction	1.3.6.1.4.1.52.4.1.3.1.2.1.1.1.4	INTEGER	read-write	The action to be performed with this ping entry.
INT nwIpPingStatus	1.3.6.1.4.1.52.4.1.3.1.2.1.1.1.5	INTEGER	read-only	The results of a ping request. A result of alive(4) means the device is responding.
nwIpTraceRoute	1.3.6.1.4.1.52.4.1.3.1.2.2
nwIpTraceRouteTable	1.3.6.1.4.1.52.4.1.3.1.2.2.1		not-accessible	This table allows outbound traceroute requests to be generated from the Cabletron device to a specified destination IP address. It is indexed by destination address and source address to allow multiple requests by different owner IP addresses.
nwIpTraceRouteEntry	1.3.6.1.4.1.52.4.1.3.1.2.2.1.1		not-accessible	An IP TraceRoute Table entry containing objects for a particular traceroute request.
