@jtk @ricci I used to run Cat 5505s and 6509-Es for many years. Honestly the 6509E was probably the most reliable box I ever had the pleasure to use even now.

When the apocalypse happens it’ll be cockroaches and 6509s left.

@jtk @ricci I am voting 5513.

Same amount of fan inlets on the 6509 and the 5513 I believe (same physical size?) but the 5513 was higher density with thinner cards.

Also seems like the supervisor is in the top slot vs the 6509 that required you to install the sup in slot 5/6 (near the bottom)

Even now we have the ability to re-create almost a full likeness of our entire DC, then do pre and post tests before touching anything in the estate.

As you know already, I’m a hyoooooge fan
