Description: Manages MRV In-Reach Ethernet interface configuration and traffic counters.

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 MRV-IN-REACH-ETHERNET-MIB?

MRV-IN-REACH-ETHERNET-MIB is a vendor-specific module for the Ethernet network interfaces on MRV Communications' In-Reach console/terminal server product line, covering interface configuration (such as speed/duplex settings) and traffic counters for the device's management/uplink Ethernet port(s). Monitoring emphasis is on interface operational status and traffic statistics: link state, packet/byte counters, and error counters reveal the health of network connectivity to the device's management interface. It likely complements the standard IF-MIB for generic interface objects, adding In-Reach-specific configuration on top. It is part of MRV's proprietary In-Reach MIB family, alongside the chassis and character-mode companion modules. Typical deployment is remote or branch-office racks where an MRV In-Reach console server's Ethernet uplink needs continuous availability monitoring. Engineers can download the MRV-IN-REACH-ETHERNET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in MRV-IN-REACH-ETHERNET-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.

Supported Devices

MRV In-Reach console/terminal server Ethernet interface

Monitoring Examples

No sample objects were provided in this source excerpt, so specific table or leaf object names can't be honestly cited. Based on the module description, a plausible scenario would be polling Ethernet link status and traffic/error counters to detect a degraded management-network connection to the In-Reach device, but this can't be grounded in confirmed object names here.

What Can Be Monitored

Ethernet link status
traffic counters (packets/bytes)
error counters
interface configuration (speed/duplex)

OID symbolic	OID numeric	Type	Access	Description
CTR etherAlignmentErrors	1.3.6.1.4.1.33.11.1.1.2	Counter	read-only	A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.
etherEntry	1.3.6.1.4.1.33.11.1.1		not-accessible	Generic status and parameter values for an Ethernet interface.
CTR etherFCSErrors	1.3.6.1.4.1.33.11.1.1.3	Counter	read-only	A count of frames received on a particular interface that are an integral number of octets in length that do not pass the FCS check.
INT etherIndex	1.3.6.1.4.1.33.11.1.1.1	INTEGER	read-only	An index value that uniquely identifies an Ethernet interface. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
CTR etherMulticastBytesIn	1.3.6.1.4.1.33.11.3.1.2	Counter	read-only	A count of frames successfully received on a particular interface and for which the destination address multicast bit was set. Bytes that are counted by an instance of this object are also counted by the corresponding instance of the ifInOctets object.
CTR etherMulticastBytesOut	1.3.6.1.4.1.33.11.3.1.3	Counter	read-only	A count of successfully frames successfully transmitted on a particular interface and for which the destination address multicast bit was set. Bytes that are counted by an instance of this object are also counted by the corresponding instance of the ifOutOctets object.
etherMulticastEntry	1.3.6.1.4.1.33.11.3.1		not-accessible	EtherMulticast status and parameter values for an Ethernet interface.
INT etherMulticastIndex	1.3.6.1.4.1.33.11.3.1.1	INTEGER	read-only	An index value that uniquely identifies an Ethernet interface. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
etherMulticastTable	1.3.6.1.4.1.33.11.3		not-accessible	A list of etherMulticast entries.
etherTable	1.3.6.1.4.1.33.11.1		not-accessible	A list of generic entries.
etherTxEntry	1.3.6.1.4.1.33.11.2.1		not-accessible	Transmit status and parameter values for an Ethernet interface.
INT etherTxIndex	1.3.6.1.4.1.33.11.2.1.1	INTEGER	read-only	An index value that uniquely identifies an Ethernet interface. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
CTR etherTxMultipleCollisionFrames	1.3.6.1.4.1.33.11.2.1.3	Counter	read-only	A count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts or ifOutNUcastPkts object and is not counted by the corresponding instance of the etherTxSingleCollisionFrames object.
CTR etherTxSingleCollisionFrames	1.3.6.1.4.1.33.11.2.1.2	Counter	read-only	A count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of either the ifOutUcastPkts or ifOutNUcastPkts object and is not counted by the corresponding instance of the etherTxMultipleCollisionFrames object.
