Juniper MX Port Numbering

Unfortunately the juniper port numbering scheme can cause a lot of confusion for people not familiar with the layout. This can get quite confusing when explaining to remote hands on site.

I made a quick reference which I use for some of our MX480s but the principle is the same on other hardware. This is handy for sending to third parties with a port highlighted to ensure they don’t go pulling the wrong cables. :)
