Description: Manages TCP-to-serial port tunneling configuration on Colubris/HP wireless access devices.

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 COLUBRIS-TCP-SERIAL-MIB?

COLUBRIS-TCP-SERIAL-MIB is a small Colubris Networks (later HP) proprietary MIB reporting TCP-over-serial gateway status on Colubris wireless devices, a feature tunneling a serial console session over a TCP connection. Its objects report connection status, remote IP address and TCP port, connect time, and transmitted/received byte counts. As a status MIB it lets an administrator confirm a remote serial-over-TCP session is currently connected and watch its byte counters. It is deployed on Colubris Networks (HP) wireless products with serial-over-TCP support. Engineers can download the COLUBRIS-TCP-SERIAL-MIB file directly to load it into their MIB browser.

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

Colubris Networks (HP) wireless products

Monitoring Examples

An administrator checks coTCPSerialConnectionStatus and coTCPSerialConnectTime to confirm a remote serial-console-over-TCP session to a Colubris device is currently active.

What Can Be Monitored

TCP-over-serial connection status and byte counters

How to Use in IPNetwork Monitor

Example using coTCPSerialConnectTime OID:

Select a Colubris/HP wireless product (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type coTCPSerialConnectTime into the Find box to locate it in the OID tree, then select it and click OK. It reports the elapsed time. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the value is unexpectedly low (e.g. under 10 minutes), since that indicates a recent, possibly unplanned, reboot or restart. Click Finish to create the monitor; you can adjust any parameter later.
