best practice for your circuit ports make static or leave auto negotiate

[arcolino11]

Hello what is best practice for your major ports on a switch meaning the important ports like your t1 port example you plug a t1 line in that is full duplex (the switch is set to auto detect) it sets it to full duplex but should I go ahead and manually put that port to full duplex? In other words is it good practice to manually set the major ports to full or half depending on what is plugged in.

I'm not sure there is a documented best practice, but I personally hard code the speed and duplex of interfaces that connect to routers and switches. This is mainly because if the auto-negotiation fails during operation, it can have quite an impact on throughout if an interface suddenly drops from 1 Gbps Full-Duplex down to 10 Mbps Half-Duplex.
