Description: Manages SNMP-initiated ping operations and round-trip time statistics on Redback SmartEdge BRAS platforms.

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 RBN-PING-MIB?

RBN-PING-MIB is a Redback Networks (later Ericsson) enterprise MIB for the SmartEdge series Broadband Remote Access Server (BRAS) platform, extending the standard IETF DISMAN-PING-MIB (RFC 4560) with vendor-specific ping test capabilities. It exposes objects for configuring and triggering SNMP-initiated ICMP ping tests, and for retrieving per-test results and historical round-trip-time statistics. Administrators use it to actively probe network reachability and measure jitter, minimum/maximum/average round-trip time toward configured targets, effectively monitoring network-path health and latency performance as a software-driven diagnostic capability of the device. It explicitly depends on and supplements the IETF DISMAN-PING-MIB standard for its base test-control model. It is typically deployed on Redback/Ericsson SmartEdge BRAS routers in broadband/ISP access networks where operators need active reachability and latency testing toward subscriber-facing or upstream network elements. Engineers can download the RBN-PING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RBN-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 administrator would create a ping test and then poll rbnPingResultsTable/rbnPingResultsEntry for live results, including rbnPingResultsJitter to detect jitter spikes on the path. Historical results are retained in rbnPingHistoryTable/rbnPingHistoryEntry, indexed by rbnPingHistoryIndex, where rbnPingHistoryMinRtt, rbnPingHistoryMaxRtt, and rbnPingHistoryAverageRtt reveal whether round-trip time toward rbnPingHistoryIpTargetAddress is degrading over time. A sudden rise in rbnPingHistoryAverageRtt or high rbnPingResultsJitter would indicate congestion or a failing path segment, and rbnPingNotifications can alert operators when tests cross configured thresholds.

What Can Be Monitored

ping test round-trip time (min/max/average)
jitter on active ping tests
ping test history per target address
reachability of configured IP targets
number of configured ping tests

OIDs

OID symbolic	OID numeric	Type	Access	Description
rbnPingMib	1.3.6.1.4.1.2352.2.46			This Redback 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).
rbnPingObjects	1.3.6.1.4.1.2352.2.46.1
rbnPingGlobals	1.3.6.1.4.1.2352.2.46.1.1
G32 rbnPingNumTests	1.3.6.1.4.1.2352.2.46.1.1.1	Gauge32	read-only	The number of entries in the pingCtlTable.
rbnPingResults	1.3.6.1.4.1.2352.2.46.1.2
rbnPingResultsTable	1.3.6.1.4.1.2352.2.46.1.2.1		not-accessible	This table enhances the pingResultsTable, providing additional statistics for completed ping tests.
rbnPingResultsEntry	1.3.6.1.4.1.2352.2.46.1.2.1.1		not-accessible	A conceptual row in the rbnPingResultsTable.
G32 rbnPingResultsJitter	1.3.6.1.4.1.2352.2.46.1.2.1.1.1	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.
rbnPingHistoryTable	1.3.6.1.4.1.2352.2.46.1.2.2		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 rbnPingCtlMaxHistoryRows 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 rbnPingCtlMaxHistory for the corresponding entry in the rbnPingCtlTable.
rbnPingHistoryEntry	1.3.6.1.4.1.2352.2.46.1.2.2.1		not-accessible	A conceptual row in the rbnPingHistoryTable.
U32 rbnPingHistoryIndex	1.3.6.1.4.1.2352.2.46.1.2.2.1.1	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. rbnPingHistoryIndex will be assigned values starting at 1 and will wrap after exceeding the maximum possible value ('ffffffff'h).
IPt rbnPingHistoryIpTargetAddressType	1.3.6.1.4.1.2352.2.46.1.2.2.1.2	InetAddressType	read-only	This object indicates the type of address stored in the corresponding pingResultsIpTargetAddress object.
IP rbnPingHistoryIpTargetAddress	1.3.6.1.4.1.2352.2.46.1.2.2.1.3	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 rbnPingHistoryMinRtt	1.3.6.1.4.1.2352.2.46.1.2.2.1.4	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 rbnPingHistoryMaxRtt	1.3.6.1.4.1.2352.2.46.1.2.2.1.5	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.
U32 rbnPingHistoryAverageRtt	1.3.6.1.4.1.2352.2.46.1.2.2.1.6	Unsigned32	read-only	The current average ping round-trip-time (RTT).

G32 rbnPingHistorySentProbes	1.3.6.1.4.1.2352.2.46.1.2.2.1.8	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 rbnPingHistoryRttSumOfSquares	1.3.6.1.4.1.2352.2.46.1.2.2.1.9	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 rbnPingHistoryLastGoodProbe	1.3.6.1.4.1.2352.2.46.1.2.2.1.10	DateAndTime	read-only	Date and time when the last response was received for a probe.
G32 rbnPingHistoryJitter	1.3.6.1.4.1.2352.2.46.1.2.2.1.11	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.

The oldest corresponding entry in the rbnPingHistoryTable will be removed to allow the addition of a new entry once the number of corresponding rows in the rbnPingHistoryTable reaches this value. When a pingCtlTable entry is removed, all corresponding entries in the rbnPingHistoryTable will also be removed. A value of 0 for this object disables creation of rbnPingHistoryTable entries.
rbnPingIp	1.3.6.1.4.1.2352.2.46.1.4
rbnPingCtlIpTable	1.3.6.1.4.1.2352.2.46.1.4.1		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.
