Description: Provides SNMP-initiated ICMP ping tests and result reporting for network reachability on Ericsson routers.

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 ERICSSON-ROUTER-PING-MIB?

ERICSSON-ROUTER-PING-MIB extends the standard DISMAN-PING-MIB (RFC 4560) with Ericsson-specific objects for creating and monitoring SNMP-initiated ICMP ping tests on SmartEdge/SM/SSR routers. It lets an operator define ping tests and retrieve both current results and historical round-trip statistics, including jitter, minimum/maximum/average RTT, and per-test target address details, scoped per SNMP context. Functionally this is a network-reachability and performance-monitoring MIB rather than a hardware-status MIB: eriRouterPingHistoryMinRtt/MaxRtt/AverageRtt and eriRouterPingResultsJitter reveal latency or jitter degradation to a target, and repeated failed tests can indicate a reachability fault along the path being probed. It explicitly depends on and supplements the IETF DISMAN-PING-MIB (RFC 4560), reusing its ping-test framework while adding richer result/history data. It's deployed in service-provider networks to run active reachability/SLA-style probes from Ericsson routers toward peers, customer edges, or upstream targets, per SNMP context. Engineers can download the ERICSSON-ROUTER-PING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERICSSON-ROUTER-PING-MIB. 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.

Monitoring Examples

An operator creates a ping test and polls eriRouterPingResultsTable/eriRouterPingResultsEntry for eriRouterPingResultsJitter, then reviews eriRouterPingHistoryTable/eriRouterPingHistoryEntry (indexed by eriRouterPingHistoryIndex) for eriRouterPingHistoryMinRtt, eriRouterPingHistoryMaxRtt, and eriRouterPingHistoryAverageRtt toward eriRouterPingHistoryIpTargetAddress. A rising eriRouterPingHistoryAverageRtt combined with increased jitter for a specific target address suggests path congestion or a degrading link, prompting further investigation before the reachability test starts failing outright.

What Can Be Monitored

round-trip time (min/max/average)
ping jitter
ping test target address
number of configured ping tests
ping test history results

OIDs

OID symbolic	OID numeric	Type	Access	Description
eriRouterPingMib	1.3.6.1.4.1.193.218.2.46			This MIB supplements the standard Ping MIB, namely: DISMAN-PING-MIB (RFC 4560) This module defines additional objects for creating and monitoring ping tests. All MIB objects defined in this module are viewed within the context identified in the SNMP protocol (i.e. the community string in v1/v2c or the contextName in v3).
eriRouterPingObjects	1.3.6.1.4.1.193.218.2.46.1
eriRouterPingGlobals	1.3.6.1.4.1.193.218.2.46.1.1
G32 eriRouterPingNumTests	1.3.6.1.4.1.193.218.2.46.1.1.1	Gauge32	read-only	The number of entries in the pingCtlTable.
eriRouterPingResults	1.3.6.1.4.1.193.218.2.46.1.2
eriRouterPingResultsTable	1.3.6.1.4.1.193.218.2.46.1.2.1		not-accessible	This table enhances the pingResultsTable, providing additional statistics for completed ping tests.
eriRouterPingResultsEntry	1.3.6.1.4.1.193.218.2.46.1.2.1.1		not-accessible	A conceptual row in the eriRouterPingResultsTable.
G32 eriRouterPingResultsJitter	1.3.6.1.4.1.193.218.2.46.1.2.1.1.1	Gauge32	read-only	The calculated ping jitter value, which is the delta between the minimum round-trip-time (RTT) and the maximum RTT. If no RTT has been received, this object will have a value of 0.
eriRouterPingHistoryTable	1.3.6.1.4.1.193.218.2.46.1.2.2		not-accessible	Defines a table for storing the results of ping tests. This is essentially a mirror of the pingResultsTable, with the addition of an index object. The number of entries in this table is limited per entry in the pingCtlTable by the value of the corresponding eriRouterPingCtlMaxHistoryRows object. An entry in this table is created when a ping test completes. The initial 2 instance identifier index values identify the pingCtlEntry that these test results belong to. An entry is removed from the table when its corresponding pingCtlEntry is deleted. The oldest entry in this table for a corresponding entry in the pingCtlTable will be removed to allow the addition of a new entry once the number of rows in this table reaches the value specified by the eriRouterPingCtlMaxHistory for the corresponding entry in the eriRouterPingCtlTable.
eriRouterPingHistoryEntry	1.3.6.1.4.1.193.218.2.46.1.2.2.1		not-accessible	A conceptual row in the eriRouterPingHistoryTable.
U32 eriRouterPingHistoryIndex	1.3.6.1.4.1.193.218.2.46.1.2.2.1.1	Unsigned32	not-accessible	An entry in this table is created when a ping test completes. The initial 2 instance identifier index values identify the pingCtlEntry that these results belongs to. eriRouterPingHistoryIndex will be assigned values starting at 1 and will wrap after exceeding the maximum possible value ('ffffffff'h).
IPt eriRouterPingHistoryIpTargetAddressType	1.3.6.1.4.1.193.218.2.46.1.2.2.1.2	InetAddressType	read-only	This object indicates the type of address stored in the corresponding pingResultsIpTargetAddress object.
IP eriRouterPingHistoryIpTargetAddress	1.3.6.1.4.1.193.218.2.46.1.2.2.1.3	InetAddress	read-only	This object reports the IP address associated with a pingCtlTargetAddress value when the destination address is specified as a DNS name. The value of this object should be a zero-length octet string when a DNS name is not specified or when a specified DNS name fails to resolve. The address type (InetAddressType) that relates to this object is specified by the corresponding value of pingResultsIpTargetAddressType.
U32 eriRouterPingHistoryMinRtt	1.3.6.1.4.1.193.218.2.46.1.2.2.1.4	Unsigned32	read-only	The minimum ping round-trip-time (RTT) received. A value of 0 for this object implies that no RTT has been received.
U32 eriRouterPingHistoryMaxRtt	1.3.6.1.4.1.193.218.2.46.1.2.2.1.5	Unsigned32	read-only	The maximum ping round-trip-time (RTT) received. A value of 0 for this object implies that no RTT has been received.

G32 eriRouterPingHistorySentProbes	1.3.6.1.4.1.193.218.2.46.1.2.2.1.8	Gauge32	read-only	The value of this object reflects the number of probes sent for the corresponding pingCtlEntry and pingResultsEntry. The value of this object MUST be reported as 0 when no probes have been sent.
U32 eriRouterPingHistoryRttSumOfSquares	1.3.6.1.4.1.193.218.2.46.1.2.2.1.9	Unsigned32	read-only	This object contains the sum of the squares for all ping responses received. Its purpose is to enable standard deviation calculation. The value of this object MUST be reported as 0 when no ping responses have been received.
DAT eriRouterPingHistoryLastGoodProbe	1.3.6.1.4.1.193.218.2.46.1.2.2.1.10	DateAndTime	read-only	Date and time when the last response was received for a probe.
G32 eriRouterPingHistoryJitter	1.3.6.1.4.1.193.218.2.46.1.2.2.1.11	Gauge32	read-only	The calculated ping jitter value, which is the delta between the minimum round-trip-time (RTT) and the maximum RTT. If no RTT has been received, this object will have a value of 0.

U32 eriRouterPingCtlMaxHistoryRows	1.3.6.1.4.1.193.218.2.46.1.3.1.1.1	Unsigned32	read-create	The maximum number of corresponding entries allowed in the eriRouterPingHistoryTable. The oldest corresponding entry in the eriRouterPingHistoryTable will be removed to allow the addition of a new entry once the number of corresponding rows in the eriRouterPingHistoryTable reaches this value. When a pingCtlTable entry is removed, all corresponding entries in the eriRouterPingHistoryTable will also be removed. A value of 0 for this object disables creation of eriRouterPingHistoryTable entries.
eriRouterPingIp	1.3.6.1.4.1.193.218.2.46.1.4
eriRouterPingCtlIpTable	1.3.6.1.4.1.193.218.2.46.1.4.1		not-accessible	This table enhances the pingCtlTable, providing additional options for IPv4 ping tests. These objects are ignored in conceptual rows where the pingCtlType instance does not equal pingIcmpEcho.
