These are the basic settings for the switch ports:
Description
The description of the switch port. The limit is 18 characters.
We recommend providing a port description to help identify the port during monitoring
and troubleshooting. The description can be the location of the connected device or the
name of the person using the connected device.
Enable
The state of the switch port. The default is Enable.
Disable the port to administratively (manually) shut it down.
Speed
The operating speed of the switch port. Choose the speed or choose Auto
(autonegotiation) if the connected device can negotiate the link speed with the switch
port. The default is Auto.
We recommend using the default so that the speed setting on the switch port
automatically matches the setting on the connected device. Change the switch port speed
if the connected device requires a specific speed.
Duplex
The duplex mode of the switch port. Choose the duplex mode:
•
Auto (autonegotiation) if the connected device can negotiate with the switch
•
Full (full duplex) if both devices can send data at the same time
•
Half (half duplex) if one or both devices cannot send data at the same time
The default is Auto.
Note
On Gigabit Ethernet ports only, you cannot set the port to half duplex if the port
speed is set to Auto.
We recommend using the default so that the duplex setting on the switch port
automatically matches the setting on the connected device. Change the duplex mode on
the switch port if the connected device requires a specific mode.
Auto-MDIX
Whether the automatic medium-dependent interface crossover (auto-MDIX) feature will
automatically detect the required cable connection type (straight-through or crossover)
and configure the connection appropriately. The default is Enable.
This setting is not available on the SFP module ports.
Note
To reenable auto-MDIX, first set the duplex mode and speed to Auto.
