Important Considerations
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
module prompts you to choose the setting and then applies it to all of
the ports.
When you enable autonegotiation, the module ignores your
requested portMode information for 10/100BASE-TX ports and your
requested flowControl information for 1000BASE-SX ports.
When you disable autonegotiation, the module recognizes the
requested portMode values for ports that have portMode options and
the requested flowControl values for 1000BASE-SX ports.
(100BASE-FX ports and backplane ports do not support
autonegotiation.)
Therefore, it is extremely important that you understand how to
implement flowcontrol and portMode in your network. See the
Switch 4007 Implementation Guide for more information.
