Description: Manages virtual terminal protocol sessions and console redirection on CommWorks/3Com equipment.

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 USR-VTP-MIB?

USR-VTP-MIB is a CommWorks/3Com (formerly U.S. Robotics) enterprise MIB that manages the Virtual Terminal Protocol (VTP), a mechanism for console redirection and remote virtual-terminal sessions on their access/remote-access equipment. It exposes configuration and session-state data for VTP connections, such as session parameters and console redirection settings, rather than deep hardware sensors. Its monitoring relevance is chiefly around software/session status -- confirming whether virtual terminal sessions are active, correctly configured, or failing to establish -- which is useful for diagnosing remote management/console-access problems on the device. No specific dependency on other standard MIBs is evident from the available description; it appears to be a self-contained legacy enterprise MIB. It is typically deployed on legacy USRobotics/CommWorks/3Com remote access servers and modem/dial-up gateway equipment. Engineers can download the USR-VTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in USR-VTP-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

USRobotics/CommWorks remote access server
3Com dial-up/modem gateway

Monitoring Examples

An administrator would monitor VTP session objects to verify that a virtual terminal/console-redirection session to the device is active and using the expected parameters. Because sample_objects were empty in the source, no concrete table or object names can be cited; a realistic scenario would involve checking session state to detect why remote console access is failing to establish. This MIB's runtime data appears limited to VTP session and configuration state rather than broad device telemetry.

What Can Be Monitored

VTP session status
console redirection configuration
