Field
Negotiation
If you know what the communication setting of the host is, you can
optionally set the negotiation speed and mode of the management port(s)
to match. If you do not know the communication setting on the host, leave
the setting at Auto and let the controller query the host and set the port to
the appropriate speed and duplex mode.
When you have completed the settings, click Next> to continue to the next
screen. Note that the settings you have made are not saved until you
complete the wizard settings and select Confirm on the last screen of the
wizard.
NOTE:
• If the management console is directly connected to a management port
on one controller, enter settings only for that controller (you will
configure the management port settings for the other controller later).
• If the management console is connected via a switch or hub, you can
enter settings for both management controllers now.
