Hardware address |
MAC address of the hardware. |
detail extensivenone |
Last flapped |
Date, time, and how long ago the interface went from down to up. The format is Last flapped: year-month-day hour:minute:second timezone (hour:minute:second ago). For example, Last flapped: 2008–01–16 10:52:40 UTC (3d 22:58 ago). |
detail extensivenone |
Statistics last cleared |
Time when the statistics for the interface were last set to zero. |
detail extensive |
Traffic statistics |
Number and rate of bytes and packets received and transmitted on the physical interface.
Note: The bandwidth bps counter is not enabled on this platform. |

detail extensive |
Queue counters (Egress ) |
CoS queue number and its associated user-configured forwarding class name.
|
detail extensive |
Active alarms and Active defects |
Ethernet-specific defects that can prevent the interface from passing packets. When a defect persists for a certain amount of time, it is promoted to an alarm. Based on the switch configuration, an alarm can ring the red or yellow alarm bell on the switch, or turn on the red or yellow alarm LED on the craft interface. These fields can contain the value None or Link.

Generation |
Unique number for use by Juniper Networks technical support only. |
detail extensive |
Route Table |
Route table in which the logical interface address is located. For example, 0 refers to the routing table inet.0. |
detail extensivenone |
Flags |
Information about protocol family flags. If unicast Reverse Path Forwarding (uRPF) is explicitly configured on the specified interface, the uRPF flag displays. If uRPF was configured on a different interface (and therefore is enabled on all switch interfaces) but was not explicitly configured on the specified interface, the uRPF flag does not display even though uRPF is enabled. |
detail extensive |
protocol-family |
Protocol family configured on the logical interface. If the protocol is inet, the IP address of the interface is also displayed. |
