to the port. After the problem has been fixed, you can enable the
port again to resume normal operation.
You might also want to disable a port that is not being used to
secure it from unauthorized connections.
Possible settings for this parameter are:
Enabled - The port receives and forwards packets. This is the
default setting.
Disabled - The port does not receive or forward packets.

6 - Negotiation
You use this option to configure a port for autonegotiation or to
manually set a port’s speed and duplex mode. The default is Auto.
Note
When you set negotiation to Manual, options 7 (Speed), 8 (Duplex),
and 9 (MDI Crossover) are displayed.
If you select Auto for autonegotiation, which is the default setting,
the switch sets speed, duplex mode, and MDI crossover for the
port automatically. The switch determines the highest possible
common speed between the port and its end node and sets the
port to that speed. This helps to ensure that the port and the end
node are operating at the highest possible common speed.
Note the following items concerning the operation of
autonegotiation on the switch port:
❑ In order for a switch port to successfully autonegotiate its duplex
mode with an end node, the end node should also be using
autonegotiation. Otherwise, a duplex mode mismatch can occur.
