Hey guys,
I was looking to put ports into an unroutable vlan and was hoping to
use the LAST INPUT field in the show interface command. I ran into
the below output. The interface is showing up/up, mac address table
is showing a device behind the port and I can ping the device. The
device is a scanner/printer.
I thought that last input field is supposed to tell you the last time
a packet was successfully received. Anyone run into this before?
Perhaps a bug in the IOS or just in my head?
