Port Speeds
SFP ports are capable of transmitting and receiving at 2-Gbit/sec, 4-Gbit/sec, or 8-
Gbit/sec. XPAK ports are capable of transmitting and receiving at 10-Gbit/sec or 20-
Gbit/sec. All ports can be configured for either a fixed transmission speed or to
sense (auto-detect) the transmission speed of the device to which it is connected. To
display the speed of each port, open the View menu and select View Port Speeds.
Note – 8-Gbit/sec SFPs do not support 1-Gbit/sec speed. You should not set the
port speed to 1-Gbit/sec if an 8-Gbit/sec SFP is inserted, as the port will be downed
if you do.
To change the port transmission speed, do the following:
1. Select one or more SFP ports in the faceplate display.
a. Open the Port menu and select Port Properties to open the Port Properties
dialog.
a. Select the Port Speed option from the drop-down list.
a. Click the OK button to write the new port speed to the switch.
TABLE 4-7 lists the possible port speeds.

State Description
Auto-Detect Matches the transmission speed of the connected device. This is the
default for SFP and XPAK.
2Gbps Sets the transmission speed to 2-Gbps.
4Gbps Sets the transmission speed to 4-Gbps.
8Gbps Sets the transmission speed to 8-Gbps
10Gbps Sets the transmission speed to 10-Gbps
20Gbps Sets the transmission speed to 20-Gbps
