SEC-FLOW-MIB

Description: Monitors security flow inspection statistics including connection rates and policy match counts.

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.

SEC-FLOW-MIB is a vendor MIB (prefix "nbsAr", tied to an "Accelerouter" product referenced as nbsAccelerouter) for monitoring security-flow inspection state on flow-based security/accelerator networking equipment. It belongs to the network-security/flow-inspection management category, exposing a per-flow table tracking flow validity, state, last-used timestamp, and associated service/QoS bindings. Its monitoring value is centered on software/service state: nbsArSecFlowState and nbsArSecFlowValid reveal whether a given security flow entry is currently active and legitimate, nbsArSecFlowLastUsedTimestamp indicates flow idle/aging behavior, and nbsArSecFlowNumOfServices together with nbsArSecFlowServId/nbsArSecFlowServTypes show which security services are bound to a flow — useful for confirming policy enforcement and catching stale or anomalous flow entries. No explicit external standards dependency is stated, but it appears tied to the vendor's own flow/QoS framework (nbsArFlowID, nbsArFlowQoSSpec) alongside this security-specific extension. It is deployed on the vendor's security-flow-inspection network appliances (accelerouters) sitting in-line in networks that need per-flow security policy enforcement and rate/QoS control. Network engineers evaluating or troubleshooting this functionality can download the SEC-FLOW-MIB file directly to load it into their MIB browser.

An operator would poll nbsArSecFlowTable/nbsArSecFlowEntry, indexed by nbsArSecFlowIndex, checking nbsArSecFlowValid and nbsArSecFlowState for a suspicious connection, and inspect nbsArSecFlowServTypes/nbsArSecFlowServId to see which security services are applied to it. A flow with nbsArSecFlowLastUsedTimestamp far in the past despite nbsArSecFlowValid still being true would indicate a stale flow-table entry not being cleaned up, potentially consuming flow-table capacity. Comparing nbsArSecFlowNumOfServices against the expected policy count for a given flow type helps confirm all intended security services are correctly bound.
