Parameter
minutes: Value of delay time in minutes, and its value ranges from 0 to 1000. If
the previous call failed at one destination, the X.25 won't send calls to such a
destination again within the time set by this command.
By default, the delay time is 0.
Description
Using the x25 timer hold command, you can set the delay to send calls to a
destination with failed calls. Using the undo x25 timer hold command, you can
restore its default value.
Frequently sending call requests to a wrong destination (which does not exist or is
faulty) will deteriorate the operating efficiency of the 3Com series router. The use
of this function can avoid this problem to a certain extent. If this parameter is set
to 0, it is equal to disabling the function. In addition, this function is only effective
to the calls originated from the local. That is to say, this parameter is meaningless
when the X.25 operates in the switching mode.
For the related command, see display interface.
Example
Set the parameter of the X.25 interface Serial0/0/0 to 5 minutes.
[3Com-Serial0/0/0] x25 timer hold 5
