Description: Tivoli/Cisco IPsec Tier 1 MIB providing SNMP objects for monitoring IPsec security associations and related IKE 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 IPsecT1-MIB?

IPsecT1-MIB, associated with Tivoli/Cisco management tooling, is a MIB module for managing the IP Security Protocol, modeling IPsec security associations (SAs) and related IKE (Internet Key Exchange) statistics at a foundational tier. It exposes objects describing SA state, cryptographic parameters, and IKE negotiation counters. Its primary monitoring value is software/security-service status, verifying that IPsec tunnels and SAs are established and that IKE negotiations are succeeding, which is critical for detecting VPN outages, rather than any physical hardware indicator. It is closely tied to the IPsec/IKE protocol standards it manages and is often layered alongside vendor-specific VPN MIBs. Typical deployment is routers, firewalls, or VPN gateways terminating IPsec tunnels in enterprise or service-provider networks. Engineers can download the IPsecT1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in IPsecT1-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, firewalls, and VPN gateways

Monitoring Examples

No sample objects were captured for this MIB; based on the module description, an admin would typically poll IPsec security-association status and IKE statistics to confirm a tunnel is active and its keys are being renegotiated on schedule, with a stuck or absent SA indicating a failed IKE negotiation.

What Can Be Monitored

  • IPsec security association status
  • IKE negotiation statistics
  • SA cryptographic parameters
  • tunnel establishment state

RFC description

IPsec Flow Monitoring MIB that provides management objects for monitoring, accounting, and error detection across IPsec Phase-1 and Phase-2 operations, tunnel status, and security associations.
