Hey guys, I found this neat TCL script to flap interfaces in a lab technology to simulate link flap..
Just dump these into tclsh:
proc sleep {n} {
after [expr {int($n*1000)}]
}
proc simFlap args {
set data [split $args " "]
set numtimes [lindex $data 2]
regsub -all {[^0-9A-Za-z]} $numtimes "" numtimes
for {set i 0} {$i<[expr {int($numtimes)}]} {incr i} {
ios_config "interface [lindex $data 0]" "shutdown"
sleep [lindex $data 1]
ios_config "interface [lindex $data 0]" "no shutdown"
sleep [lindex $data 1]
}
}
Then you run it with " simFlap se0/0 5 10" <-- 10 times with 5sec between each
flap.. you can change the interface name and timer values as you please.. and
then practice dealing with flapping links in the topology :) not sure if this
will be useful for the real labs but it sure is cool..
Bestu kveðjur / Regards
