Hi all, Im using perl to connect on a cisco routers and make some changes ... the script works ok ... but i have some problem if some of the routers are off ... i have for example 100 router and it start from first one and goes one, when some way on a 20 tih router ( and he is off ) it stop. So how can i modify to continue if some of the routers are off and write something in the log file that that device is off .... im using Net::Telnet::Cisco and have this 

use Net::Telnet::Cisco;

for ($i = 1; $i <= 254; $i++){
$device = "172.16.$i.251";

  my $session = Net::Telnet::Cisco->new(Host => "$device",
            Input_log => "perllogrouter/router$i.log",);

   $session->login('admin', 'admin');
   #some command
   $session->cmd ("show running-config ");
   $session->close;

[download]

and if some router is down the script stop, not continue. So my solution is to put "if" where with ping command check if the host is alive or not ... but i think you all can come with better solution tnx in advanced ...
