JUNOS 8.2 Interfaces Command Reference

Have the routing protocol process display its view of 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 software disagree about the state of an interface.

Options

none — Display standard information about the state of all router interfaces on all logical routers.

logical-router (all | logical-router-name) — (Optional) Perform this operation on all logical routers or on a particular logical router.

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.

Output Fields

Table 19 lists the output fields for the show interfaces routing command. Output fields are listed in the approximate order in which they appear.

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 MTU size has changed. UpDown—The interface has made an up or down transition.	detail
Metric	Metric value on the interface.	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—MTU 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.	detail
