Port Settings Print  

To display the Port Settings window, choose Configure > Port Settings.

The Port Settings window provides configuration settings for the switch ports. These settings determine how the switch ports forward data to the devices to which they are connected. You can change these settings to fit your network needs.

You can sort the contents in each table column either alphabetically or numerically. To sort a table column, click the column heading.

To save any changes that you make in this window, click Submit. To discard any unsaved changes, click Cancel.

Column Explanation
Port

The number of the switch port, including port type (such as Fa for Fast Ethernet and Gi for Gigabit Ethernet), the module slot number (0, 1, or 2), and the specific port number.

Note that:

  • EtherSwitch service module port 1/0/2, for 16-port, 24-port, and 24-port stackwise modules, provides an internal 1000-Mbps connection.
  • EtherSwitch service module port 1/0/4, for 48-port modules, provides an internal 1000-Mbps connection.
Enabled

The state of the switch port. Check Enabled to enable the port. Uncheck Enabled to administratively (manually) shut down the port.

Speed

The operating speed of the switch port. Choose the speed from the drop-down list. You can choose Auto (autonegotiation) if the connected device can negotiate the link speed with the switch port.

The default settings are:

  • 1000 for the internal 1000-Mbps ports.
  • 1000 for the external 1000-Mbps ports (SFP).
  • Auto for the external 10/100-Mbps Fast Ethernet ports.
  • Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports.

Notes:

  • The speed on the internal ports is nonconfigurable.
  • Flow control does not apply to the internal ports.
Duplex

The duplex mode of the switch port. Choose the duplex mode from the drop-down list:

  • 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 settings are:

  • Full for the internal 1000-Mbps ports.
  • Full for the external 1000-Mbps ports (SFP).
  • Auto for the external 10/100-Mbps Fast Ethernet ports.
  • Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports.

Notes:

  • The duplex mode on internal ports is nonconfigurable.
  • You cannot set the port to half duplex if the port speed is set to Auto.
