Port speeds SFP ports with 8Gb SFPs installed are capable of transmitting and receiving at 2 Gb/s, 4 Gb/s, or 8 Gb/s. 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. See Table 24 for the possible port speeds. NOTE: 8 Gb/s SFPs do not support 1 Gb/s speed. You should not set the port speed to 1 Gb/s if an 8 Gb/s SFP is inserted, as the port will be downed if you do. To change the port transmission speed: 1. Select one or more ports in the faceplate display. 2. Open the Port menu and select Port Properties to open the Port Properties dialog box. 3. Select the Port Speed option from the drop-down list. 4. Click OK to write the new port speed to the switch. Table 24 Port speeds State Description Auto-Detect Matches the transmission speed of the connected device. This is the default. 1 Gb/s Fixed 1 Gb/s transmission speed 2 Gb/s Fixed 2 Gb/s transmission speed 4 Gb/s 8 Gb/s Fixed 4 Gb/s transmission speed Fixed 8 Gb/s transmission speed Port transceiver media status To display transceiver media status, open the View menu and select View Port Media.
