You have an easy-to-miss typo in the script.   my %args = ( hostname => "router", version = "1" ); should be   my %args = ( hostname => "router", version => "1" ); The typo has the effect of propogating an undefined value into the options being passed to NET::SNMP->session().

Compiling with -w would have kicked this out right away.

Hold on there... This won't run at all. You must have made a typo when typing in the code. Please paste in the code you're running, rather than retyping it.
