Edit Port A and Port B.
Fiber ports can only be set to 1000 Mbps line speed and full duplex. Although the port might negotiate different settings, you cannot arbitrarily downgrade line speed on a fiber Gigabit Ethernet port.

Procedure

  1. Select Devices All Devices [device name] Network Configuration Ports.
  2. Check the IPS Segments table to determine which port number is associated with Port A and which port number is associated with Port B.
  3. From the Ports table, select the entry that corresponds to the Port entry in the IPS Segments table, and then click Edit. The Port Details - Edit dialog displays.
  4. For Hardware, modify the On check box if the hardware is physically on or off.
  5. For Auto-Negotiation, modify the Enabled check box if the port allows auto-negotiation for line speed.
    Note
    Note
    If you use a copper-fiber translator (such as Netgear), you should leave Auto-Negotiation disabled.
  6. If you are not using Auto Negotiation, modify the following settings:
    • Line Speed.
    • Duplex setting: Full or Half.
  7. Click OK.
  8. Repeat steps for Port B.
