I noticed the license is a length 7 numeric value, so I modified an existing script floating around for the Summit 400-48t. Should work with any Summit 200/300/400 however.
You may need to modify the “Summit400” near the end of the file to match your prompt. This runs much quicker than I’d think; got my license after 4 hours or so.
Uncomment the dump.log line if you have trouble to debug
#!/usr/bin/perl
use Net::Telnet;
use warnings;
$t = new Net::Telnet(
Timeout => 10,
# Dump_Log => "dump.log",
Prompt => '/\* Summit*$/',
Errmode=>'die'
);
$t->open('SWITCHIPADDRESS');
$t->waitfor('/login: $/i');
$t->print('admin');
$t->waitfor('/password: $/i');
$t->print('YOURPASSWORD');
$t->waitfor('/Summit400/i');
for($x = 1; $x < 9999999; ++$x)
{
print "Trying: $x\n";
#@lines = $t->cmd("enable license advanced-edge $x");
$t->print("enable license advanced-edge $x");
$t->waitfor('/Summit400/i');
}
Thanks for this – very useful. it’s only testing 20 per second for me, which means it will take about a week to try all the combinations. Any idea where I can get the latest firmware for this switch? I tried changing logging settings on the switch to speed things up but it didn’t help.
Hey Matt,
Sorry for the late reply here. Guessing after all this time it worked though! 😉
Otherwise I just left it in a screen session and it got it in a few hours. The serial is almost never as long as the possible number of digits.
Summit is much better than cisco about firmware; if you shoot them an email with your switch serial number they’ll let you make an account and give you access to the firmware. I got my switch off ebay and they didn’t give me much hassle (a few e-mails back and forth)
I believe they wanted a picture of the serial number for verification (to prove I actually had the switch)
