Select Interfaces > Ports.The page lists Gigabit Ethernet and 10-Gigabit Ethernet interfaces and their link status.NOTE: After you make changes to the configuration in this page, you mustcommit the changes immediately for them to take effect. To commit allchanges to the active configuration, select Commit Options > Commit. See“Using the Commit Options to Commit Configuration Changes (J-WebProcedure)” on page 334 for details about all commit options.2. Select the interface you want to configure.
