Additional Information
The operational state is the physical state of the
interface. If the interface is physically operational,
even if it is not configured, the operational state is Up.
An operational state of Down indicates a problem with
the physical interface.
Interfaces are enabled by default. To disable an
interface:
In the J-Web configuration editor,
select the Disable check box on the
Interfaces> interfaces-name page.
In the CLI configuration editor, add the
disable statement at the [edit interfaces
interfaces-name ] level of the configuration
hierarchy
Configure alarms on interfaces as follows:
In the J-Web configuration editor, on the
Chassis>Alarm> interface-type page
In the CLI configuration editor, with the alarm
statement at the [edit chassis] level of the
configuration hierarchy
If the interface is saturated, this number increments
once for every packet that is dropped by the Services
Router's random early detection (RED) mechanism.
