Output Fields
Table 1 lists
the output fields for the show interfaces (virtual loopback
tunnel) command. Output fields are listed in the approximate order
in which they appear.
Field Name |
Field Description |
Level of Output |
|---|---|---|
| Physical Interface | ||
Physical interface |
Name of the physical interface. |
All levels |
Enabled |
State of the interface. Possible values are described in the “Enabled Field” section under Common Output Fields Description. |
All levels |
Interface index |
Physical interface's index number, which reflects its initialization sequence. |
detail extensive none |
SNMP ifIndex |
SNMP index number for the physical interface. |
detail extensive none |
Generation |
Unique number for use by Juniper Networks technical support only. |
detail extensive |
Type |
Type of interface. |
All levels |
Link-level type |
Encapsulation used on the physical interface. |
All levels |
MTU |
MTU size on the physical interface. |
All levels |
Speed |
Speed at which the interface is running. |
All levels |
Hold-times |
Current interface hold-time up and hold-time down, in milliseconds. |
detail extensive |
Device flags |
Information about the physical device. Possible values are described in the “Device Flags” section under Common Output Fields Description. |
All levels |
Input Rate |
Input rate in bits per second (bps) and packets per second (pps). |
None specified |
Output Rate |
Output rate in bps and pps. |
None specified |
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.
|
detail extensive |
| Logical Interface | ||
Logical interface |
Name of the logical interface. |
All levels |
Index |
Logical interface index number, which reflects its initialization sequence. |
detail extensive none |
SNMP ifIndex |
Logical interface SNMP interface index number. |
detail extensive none |
Generation |
Unique number for use by Juniper Networks technical support only. |
detail extensive |
Flags |
Information about the logical interface. Possible values are described in the “Interface Flags” section under Common Output Fields Description. |
All levels |
Encapsulation |
Encapsulation on the logical interface. |
All levels |
Input packets |
Number of packets received on the logical interface. |
None specified |
Output packets |
Number of packets transmitted on the logical interface. |
None specified |
Bandwidth |
Bandwidth allotted to the logical interface, in kilobytes per second. |
All levels |
Traffic statistics |
Total number of bytes and packets received and transmitted on the logical interface. These statistics are the sum of the local and transit statistics. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize.
|
detail extensive |
Transit statistics |
Statistics for traffic transiting the router. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize. |
detail extensive |
protocol-family |
Protocol family configured on the logical interface. Possible values are described in the “Family Flags” section under Common Output Fields Description. |
brief |
Protocol |
Protocol family configured on the logical interface. Possible values are described in the “Family Flags” section under Common Output Fields Description. |
detail extensive none |
MTU |
Maximum transmission unit size on the logical interface. |
detail extensive none |
Maximum labels |
Maximum number of MPLS labels configured for the MPLS protocol family on the logical interface. |
detail extensive none |
Generation |
Unique number for use by Juniper Networks technical support only. |
detail extensive |
Route Table |
Routing table in which the logical interface address is located. For example, 0 refers to the routing table inet.0. |
detail extensive |
Flags |
Information about protocol family flags. Possible values are described in the “Family Flags” section under Common Output Fields Description. |
detail extensive none |
