•

1000BASE-T does not support forced mode. Auto-negotiation should 

always be used to establish a connection over any 1000BASE-T port or 

trunk.

•

When auto-negotiation is enabled the switch will negotiate the best 

settings for a link based on the 

capabilities

 command. When auto-

negotiation is disabled, you must manually specify the link attributes 

with the 

speed-duplex

 and 

flowcontrol

 commands.

•

If auto-negotiation is disabled, auto-MDI/MDI-X pin signal configuration 

will also be disabled for the RJ-45 ports.
