lan.timedwait

This attribute contains the LAN timed-wait state interval.

Type TSP-Link accessible Affected by Where saved Default value

Attribute (RW) Yes LAN restore defaults Nonvolatile memory 20 (20 s)

Usage

timeout = lan.timedwait

lan.timedwait = timeout

timeout

The LAN timed-wait state interval in seconds

Details

This attribute controls the amount of time that resources are allocated to closed TCP connections. When a TCP

connection is closed, the connection is put in a timed-wait state and resources remain allocated for the

connection until the timed-wait state ends. During the timed-wait interval, the instrument processes delayed

packets that arrive after the connection is closed.

Use this attribute to tailor the timed-wait state interval for the instrument.
