Description: MIB for IPsec VPN tunnel table information and status on Beijing Topsec network security appliances

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 TOS-IV?

This is a Beijing Topsec MIB for their network security appliances (firewalls/UTM devices), specifically modeling IPsec VPN tunnel information in a conceptual table. It exposes IPsec tunnel-related status objects, per the module's own description of "a conceptual table containing TOS IV information," though the specific object names were not available in this sample. It is intended for monitoring the software/security status of VPN tunnels on the appliance, such as tunnel establishment/operational state, which reveals whether a site-to-site or remote-access IPsec connection is currently up or has failed. No explicit dependency on other standard MIBs is evident from the available description. It is typically deployed on Topsec firewall/VPN gateway appliances in enterprise or service-provider security infrastructure where IPsec tunnel status needs to be tracked via SNMP. Engineers can download the TOS-IV file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TOS-IV. 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

  • Beijing Topsec firewall/VPN security appliances

Monitoring Examples

An admin would poll the module's IPsec tunnel table (as described, "the conceptual table containing TOS IV information") to check the status of active IPsec tunnels; a tunnel entry unexpectedly disappearing or reporting a down state would indicate a dropped VPN connection needing investigation. Because no specific object names were included in the available sample data, exact OID-level detail cannot be given honestly beyond what the module description states. This limits the specificity of any monitoring scenario until the raw MIB source is consulted directly.

How to Use in IPNetwork Monitor

Example using ivInfoOutPkts OID:

Select a Beijing Topsec firewall or VPN security appliance 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 ivInfoOutPkts into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total tx packet of the whole iv tunnels . 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 counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
