get_environment fails on Cisco 4500 #182

Closed piter50 closed 6 years ago

piter50 commented 6 years ago

Description of Issue/Question

In cisco 4500s, running show memory statistics does not contain a line about IO so the io_used_mem variable is never populated and used/total memory are not able to be calculated. It only shows:

                Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
Processor   13EE25FC   470931968   255221392   215710576   212089332   215161588
