| Interface
Summary | |
|
Interface Name
|
Name of interface.
(See the interface naming conventions in the JUNOS Software Interfaces and Routing Configuration Guide.)
|
Click an interface name to see more information about the interface.
Channelized interfaces appear as two interfaces, which can both
be monitored. For example:
- If ce1-3/0/0 is configured as a clear channel,
you can monitor ce1-3/0/0 and e1-3/0/0.
- If ct1-3/0/1 is channelized, you can monitor ct1-3/0/1 and ds-3/0/1:1.
|
|
Oper State
|
Link state of the interface: Up or Down.
|
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.
|
|
Admin State
|
Whether the interface is enabled up (Up) or disabled
(Down).
|
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

|
Description
|
Configured description for the interface.
| |
| Interface: interface-name |
|
State
|
Link state of the interface: Up or Down.
|
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.
|
|
Admin State
|
Whether the interface is enabled up (Up) or disabled
(Down).
|
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
|
|
MTU
|
Maximum transmission unit (MTU) size on the physical interface.
| |
|
Speed
|
Speed at which the interface is running.
| |
|
Current Address
|
Configured media access control (MAC) address.
| |
|
Hardware Address
|
Hardware MAC address.
| |
|
Last Flapped
|
Date, time, and how long ago the interface changed state from Down to Up.
| |
|
Active Alarms
|
List of any active alarms on the interface.
|
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
|
|
Traffic Statistics
|
Number of packets and bytes received and transmitted on the
physical interface.
| |
|
Input Errors
|
Input errors on the interface. (See the following rows of this
table for specific error types.)
| |
|
Drops
|
Number of packets dropped by the output queue.
|
If the interface is saturated, this number increments once for
every packet that is dropped by the device's random early
detection (RED) mechanism.
|
|
Framing errors
|
Sum of ATM Adaptation Layer (AAL5) packets that have frame check
sequence (FCS) errors, AAL5 packets that have reassembly timeout errors,
and AAL5 packets that have length errors.
| |
|
Policed discards
|
Number of packets dropped as a result of routing policies configured
on the interface.
