Executing multiple IOS commands one after the other with a delay

Question

Hi -
As part of my monitoring solution, I have scheduled scripts running on my routers to do various tasks, now I am trying to do trace route to about 10 routers from a seed router to track the path of the trace and if it changes i would be alerted.
What I am having difficulty is doing one trace commands from a text file. Example follows:
Trace 10.10.10.1
Trace 10.20.10.1
Trace 10.30.10.1
The command will stop right after the first line, is there a way in IOS to do a “wait” statement between each command to get this going?

Correct, you need 12.3(2)T or higher (for router IOS).  Tcl is also available in many other non-router platforms.  Yes, you do need to be enabled. for tclsh.  For EEM, though, you do not need to be enabled.  You can register an EEM policy, then anyone on the box can execute it.  EEM is also built around Tcl, so the same code could be added to such a policy.  For example:
::cisco::eem::event_register_nonenamespace import ::cisco::eem::*namespace import ::cisco::lib::*array set cliarr [cli_open]set output {}foreach host [list x.x.x.x y.y.y.y z.z.z.z] {    append output [cli_exec $cliarr(fd) "traceroute $host"]    after 3000}cli_close $cliarr(fd) $cliarr(tty_id)puts $output
EEM Tcl policies require 12.3(14)T or higher for router IOS.
