Description: Manages MRV In-Reach IP interface, routing, and ICMP configuration objects.

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-INTERNET-MIB?

MRV-IN-REACH-INTERNET-MIB is an MRV Communications proprietary MIB for the In-Reach terminal/console server product line, covering IP interface, routing, and related network-service configuration on the device — notably including SSH server port management for secure console access. The available sample objects show a substantial SSH configuration table, exposing per-port SSH settings such as the incoming TCP port, newline filtering behavior, buffered transmit timing, remote protocol, break-sequence handling, cipher mask, authentication timeout, and host key length. Its monitoring value is largely configuration and software/service-status oriented — confirming SSH access parameters are correctly set on each console port and that authentication/timeout settings match security policy, which is a software configuration audit function rather than physical hardware health monitoring. As an In-Reach product MIB it likely complements the broader In-Reach IP/console management MIB family, though no explicit standards dependency was stated beyond conventional SSH conventions. It would be deployed on MRV In-Reach console/terminal servers used for secure out-of-band management access to data-center or telecom equipment. Network engineers evaluating or troubleshooting this functionality can download the MRV-IN-REACH-INTERNET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in MRV-IN-REACH-INTERNET-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 terminal/console servers

Monitoring Examples

An administrator would poll sshPortTable/sshPortEntry to check sshPortIncomingTcpPort and sshAuthenticationTimeout for a given console port, confirming SSH access is configured on the expected TCP port with an appropriate authentication timeout, and would check sshCipherMask and sshHostKeyLength to verify the port is using approved encryption settings. A port showing an unexpectedly short sshAuthenticationTimeout or a weak sshCipherMask would flag a security-policy deviation on that console access port.

What Can Be Monitored

  • SSH port configuration per console port
  • SSH authentication timeout
  • cipher/encryption settings
  • host key length
  • remote protocol and newline filtering settings
