Port speeds
External ports are capable of transmitting and receiving at 1-Gbps, 2-Gbps, or 4-Gbps. Internal ports are
capable of transmitting and receiving at 1-Gbps or 2-Gbps. The ports can be configured for either
transmission speed or to sense the transmission speed of the device to which it is connected. Table 21 lists
the possible port speeds.
NOTE: The port speed of internal ports is pre-configured and cannot be changed.
Select View > View Port Speeds to display the speed of each port.
To change the port transmission speed for external ports:
1. Select one or more ports in the faceplate display.
2. Select Port > Port Properties to open the Port Properties dialog.
3. Select the port speed option from the drop-down list.
4. Click OK to write the new port speed to the switch.
