Description: IPSEC-TUN-MON-MIB module

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 IPSEC-TUN-MON-MIB?

IPSEC-TUN-MON-MIB is an IETF IPsec Working Group MIB monitoring logical IPsec channels and tunnels at an entity-wide level. Its global counters report current, total (cumulative), and deleted counts for both channels and tunnels, while its channel table (keyed by channel entry) records channel type and local endpoint address. As a protocol-status MIB it lets an administrator gauge overall IPsec tunnel churn (how many tunnels have been created/torn down over time) alongside the currently active count, useful for spotting tunnel instability. It is deployed on IPsec-capable routers, VPN gateways, and firewalls. Engineers can download the IPSEC-TUN-MON-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in IPSEC-TUN-MON-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

  • IPsec-capable routers, VPN gateways, and firewalls

Monitoring Examples

An administrator compares totalTunnels against currentTunnels over time to gauge whether an unusually high tunnel-churn rate (frequent creation/deletion) indicates an underlying IPsec stability problem.

What Can Be Monitored

  • current/total/deleted IPsec channel and tunnel counts

How to Use in IPNetwork Monitor

Example using totalChannels OID:

Select an IPsec-capable router/VPN gateway/firewall (tunnel/channel churn counters) 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 totalChannels into the Find box to locate it in the OID tree, then select it and click OK. The total number of channels created by the entity since system boot. 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.
