To configure switch ports:
1. Choose the port or sequential range of ports using the From Port and To Port drop-down menus.
2. Use the remaining drop-down menus to configure the parameters described below:
The fields that can be configured or displayed are described below:
Parameter Description
Unit
Select the unit you wish to configure. (EI and SI Mode Only)
From Port / To Port
Select the appropriate port range used for the configuration here.
State
Toggle the State field to either enable or disable a given port or group of ports.
Speed/Duplex
Use the drop-down menu to select the speed and full-duplex/half-duplex state of the port.
Auto denotes auto-negotiation among 10, 100 and 1000 Mbps devices, in full- or half-
duplex (except 1000 Mbps which is always full duplex). The Auto setting allows the port
to automatically determine the fastest settings the device the port is connected to can
handle, and then to use those settings. The other options are 10M Half, 10M Full, 100M
Half, 100M Full, 1000M Full_Master, and 1000M Full_Slave. There is no automatic
adjustment of port settings with any option other than Auto.
The Switch allows the user to configure two types of gigabit connections; 1000M
Full_Master, and 1000M Full_Slave. Gigabit connections only support full duplex
connections and take on certain characteristics that are different from the other choices
listed.
The 1000M Full_Master and 1000M Full_Slave parameters refer to connections running
a 1000BASE-T cable for connection between the Switch port and other device capable
of a gigabit connection. The master setting (1000M Full_Master) will allow the port to
advertise capabilities related to duplex, speed and physical layer type. The master
