show interfaces routing

Syntax

show interfaces routing <brief | detail> <interface-name> <logical-system (all | logical-system-name)>

Release Information

Command introduced before Junos OS Release 7.4.

Description

Display the state of the router's interfaces. Use this command for performing router diagnostics only, when you are determining whether the routing protocols and the Junos OS differ about the state of an interface.

Options

none

Display standard information about the state of all router interfaces on all logical systems.

brief | detail

(Optional) Display the specified level of output.

interface-name

(Optional) Name of a specific interface.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.

Additional Information

For information about how to configure routing protocols, see the Junos Routing Protocols Configuration Guide. For information about related operational mode commands for routing instances and protocols, see the Junos Routing Protocols and Policies Command Reference.

Field Name

Field Description

Level of Output

Interface

Name of the physical interface.

none brief

State

State of the physical interface: Up or Down.

none brief

Addresses

Protocols and addresses configured on the interface.

none brief

Index

Interface index number, which reflects its initialization sequence.

detail

Refcount

Number of references to the interface in the routing software.

detail

State

State (Up or Down) and type of interface.

detail

Change

Reflects one or more of the following recent changes to the interface:

  • Add—The interface was just added.
  • Address—The interface's link-layer address has changed.
  • Delete—The interface is being deleted.
  • Encapsulation—The type of encapsulation on the interface has changed.
  • Metric—The interface's metric value has changed.
  • MTU—The interface's maximim transmission unit size has changed.
  • UpDown—The interface has made an up or down transition.

detail

Up/down transitions

Number of times the interface has gone from Down to Up.

detail

Link layer

Describes the link layer of the interface.

detail

Encapsulation

Encapsulation on the interface.

detail

Bandwidth

Speed at which the interface is running.

detail

Protocol address

Information about the configuration of protocols on the interface:

  • Address—Address configured on the interface for the protocol type.
  • State—State (Up or down) and type of interface.
  • Change—Reflects one or more of the following recent changes to the interface:
    • Add—The interface was just added.
    • Address—The interface's address has changed.
    • Broadcast—The interface's broadcast address has changed.
    • Delete—The interface is being deleted.
    • Netmask—The interface's netmask has changed.
    • UpDown—The interface has made an up or down transition.
  • Preference—Preference value for the route for this address.
  • Metric—Metric value on the interface for the protocol type.
  • MTU—Maximim transmission unit value of the interface.
  • Local address—On a point-to-point link, the address of the local side of the link. Not used for multicast links.
  • Destination—For a point-to-point link, the address of the remote side of the link. For multicast links, the network address.
