traffic-analysis udp timeout inactive

Function

The traffic-analysis udp timeout inactive command configures the aging period for inactive UDP flows in intelligent traffic analysis.

The undo traffic-analysis udp timeout inactive command restores the default configuration.

Format

traffic-analysis udp timeout inactive [ inactive-interval ]

undo traffic-analysis udp timeout inactive

Parameters

Parameter Description Value

inactive-interval

Specifies the aging period for inactive UDP flows.

The value is an integer ranging from 5 to 500, in seconds. The default value is 30.

Usage Guidelines

By default, the aging period for inactive UDP flows is 30 seconds.

After intelligent traffic analysis for UDP flows is enabled, the TAP exports the flow tables that contain flow analysis results to the specified TDA which will process and graphically display the flow information.

When a UDP flow is continuously received, analysis results of the UDP flow are periodically sent to the TDA based on the block granularity. However, when the inactive time (the time from when the last UDP packet is received to the current time) of the UDP flow exceeds the configured inactive aging period, the device considers that the UDP flow is inactive (the flow is interrupted). In this case, the device forcibly sends the current flow table to the TDA and deletes it from the device. This process is called inactive aging.

Example

# Set the aging period for inactive UDP flows to 120 seconds.
<sysname> system-view
[sysname] traffic-analysis udp timeout inactive 120
