Description: Monitors TCP connection states, retransmissions, and performance 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-TCP-MIB?

USR-TCP-MIB is a CommWorks Corporation (a 3Com Company, U.S. Robotics heritage) proprietary MIB configuring TCP-process behavior on the commWorks remote-access platform. Its objects cover a config-modified flag, config file name, max connections, Nagle-algorithm status, keepalive status/interval, and an ahead-of-segment-dropped counter. As a configuration/performance MIB it lets an administrator confirm TCP tuning (Nagle, keepalive, max connections) and watch out-of-order segment drops on a CommWorks (3Com/U.S. Robotics) remote-access platform. It is deployed on CommWorks (3Com/U.S. Robotics) remote-access platforms. Engineers can download the USR-TCP-MIB file directly to load it into their MIB browser.

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

  • CommWorks (3Com/U.S. Robotics) remote-access platforms

Monitoring Examples

An administrator checks usrTcpMaxConn and usrTcpAheadofSegDropped to confirm TCP connection capacity and out-of-order segment drops on a CommWorks (3Com) remote-access platform.

What Can Be Monitored

  • TCP process configuration and segment-drop statistics
