Configuring Default Timeout Settings

You can specify global default settings for certain timers that apply for the entire interface. There are two statements of this type:

inactivity-timeout—Sets the inactivity timeout period for established flows, after which they are no longer valid.
open-timeout—Sets the timeout period for Transmission Control Protocol (TCP) session establishment, for use with SYN-cookie defenses against network intrusion.

To configure a setting for the inactivity timeout period, include the inactivity-timeout statement at the [edit interfaces interface-name services-options] hierarchy level:




inactivity-timeout seconds;

The default value is 30 seconds. The range of possible values is from 4 through 86,400 seconds. Any value you configure in the application protocol definition overrides the value specified here; for more information, see Configuring Application Protocol Properties.

To configure a setting for the TCP session establishment timeout period, include the open-timeout statement at the [edit interfaces interface-name services-options] hierarchy level:




open-timeout seconds;

The default value is 30 seconds. The range of possible values is from 4 through 86,400 seconds. Any value you configure in the intrusion detection service (IDS) definition overrides the value specified here; for more information, see Configuring Intrusion Detection Properties.
