Mysterious?

Today was one of those days when I worked on so many strange things, I don’t know how I ever learned all this random stuff. I’m sure there are a million people that could step in and learn my job over time, but right now I don’t know what my colleagues will do if I get a fever and can’t go to work. I’m trying to diversify that risk through delegation, training and documentation, but there is a ton of specialization in our environment (which I’m sure is true for many other professions as well).

Seriously, though:

switchport access vlan 360
switchport mode access
power inline auto max 30000
spanning-tree portfast
service-policy output softmax

Who talks like that?
