Hi Tobias, Clearly our last beer together happened too long ago ;-) I haven’t referred to the kb article or anything … I just wanted to mention that you can use 100G and 40G ports on the same pic as long as you don’t go above 240G per pic. Of course setting $whatever to 100G only will not work.
But this set chassis fpc 1 pic 0 port 0 speed 40g set chassis fpc 1 pic 0 port 2 speed 100g set chassis fpc 1 pic 0 port 5 speed 100g set chassis fpc 1 pic 1 port 0 speed 40g set chassis fpc 1 pic 1 port 2 speed 100g set chassis fpc 1 pic 1 port 5 speed 100g works fine. Just my 2 cents.
