■The physical interface is Enabled. If the interface is shown as Disabled, do either of the following:

■In the CLI configuration editor, delete the disable statement at the [edit interfaces interface-name]level of the configuration hierarchy.

■In the J-Web configuration editor, clear the Disable check box on the Interfaces>interface-namepage.

■The physical link is Up. A link state of Down indicates a problem with the interface module, interface port, or physical connection (link-layer errors).

■The Last Flapped time is an expected value. The Last Flapped time indicates the last time the physical interface became unavailable and then available again. Unexpected flapping indicates possible link-layer errors.

■The traffic statistics reflect expected input and output rates. Verify that the number of inbound and outbound bytes and packets matches expected throughput for the physical interface. To clear the statistics and see only new changes, use the clear interfaces statistics interface-namecommand.

■The dialer state is Active when a USB modem call is in progress.

■The LCP state is Opened when a USB modem call is in progress. An LCP state of Closed or Not Configured indicates a problem with the dialer configuration that needs to be debugged with the monitor traffic interface interface-namecommand. For information about the monitor traffic command, see “Using the monitor traffic Command” on page 246.
