Cflowd Configuration Components
Figure 32 displays the major components to configure Cflowd parameters.
Figure 32: Cflowd Configuration Components
• Active timeout — Specifies the time, in minutes, before an active flow is removed from
the active cache.
• Inactive timeout — Specifies the time, in seconds, that must elapse without a packet
matching a flow in order for the flow to be considered inactive and removed from the
active cache.
• Cache size — Specifies the maximum number of active flows to maintain in the flow
cache table. When the actual number of flows approaches the maximum cache size,
cflowd ages several flows with an accelerated timeout to ensure flow entry space is always
available.
• Overflow — Specifies the percentage of the flow cache entries removed when the
maximum number of entries is exceeded.
• Rate — Specifies the rate (N) at which traffic is sampled.
• Collector — Defines a flow data collector for cflowd data using an IP address and a port
number as identifiers. A maximum of 5 collectors can be configured.
• Aggregation — Components of this command specify the types of data to be aggregated.
• Autonomous system type — Specifies whether the autonomous system (AS) information
included in the flow data is based on the originating AS or peer AS.
