Name

ip tcp synwait-time — global

Synopsis

ip tcp synwait-time seconds
no ip tcp synwait-time seconds

Configures

The time the router waits for a TCP connection to open

Default

30 seconds

Description

This command sets the number of seconds that the router waits for a TCP connection to open, before it times out. The value must be between 3 to 300. A longer synwait-time can be useful for dial-on-demand connections where you have to wait for the line to be dialed before a connection can open. This setting applies only to traffic originating within the router, not traffic coming through the router.

Example

If you are telneting from the router to a remote site through a DDR connection, you might want to increase the synwait-time to more reasonable level so that telnet does not time out:

ip tcp synwait-time 100
