Description: H3C MIB for IPsec VPN monitoring including security associations, tunnel status, and traffic statistics.

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 H3C-IPSEC-MONITOR-MIB?

This H3C vendor MIB provides read-only monitoring of IPsec VPN tunnels on H3C routers and security gateways, focused on retrieving statistics for individual tunnels or all active tunnels. It exposes security association (SA) status and traffic statistics for IPsec tunnels, letting an operator see which tunnels are up and how much traffic they're carrying. Its monitoring emphasis is on the software/protocol status of VPN connectivity, detecting tunnels that have gone down, SAs that failed to negotiate, or unusual traffic volume/error counts on a given tunnel that could indicate a network or configuration issue. IPsec MIB monitoring generally builds on IETF IPsec MIB concepts even though this is an H3C-specific implementation. It is deployed on H3C routers, firewalls, or VPN gateways terminating site-to-site or remote-access IPsec VPN tunnels. Network engineers evaluating or troubleshooting this functionality can download the H3C-IPSEC-MONITOR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-IPSEC-MONITOR-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

  • H3C routers, firewalls, and VPN gateways

Monitoring Examples

An administrator would poll per-tunnel SA status objects to confirm a specific IPsec tunnel between two sites remains established, and check tunnel-level byte/packet counters to verify traffic is actually flowing rather than the tunnel being up but idle. A tunnel repeatedly showing SA renegotiation without stabilizing would indicate a phase 2 mismatch or a peer configuration problem. Aggregating statistics across all tunnels would help identify which site link is consuming disproportionate VPN bandwidth.

What Can Be Monitored

  • IPsec tunnel status
  • security association (SA) state
  • per-tunnel traffic statistics
  • tunnel error/renegotiation counts

How to Use in IPNetwork Monitor

Example using h3cIPSecGlobalInOctets OID:

Select an H3C router, firewall, or VPN gateway 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 h3cIPSecGlobalInOctets into the Find box to locate it in the OID tree, then select it and click OK. The total number of octets received by all current and previous IPSec Phase-2 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 Counter64-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.
