Junos OS 12.1 Interfaces Command Reference

Within the context of a logical system, logical system administration is confined to the
resources assigned to that logical system.
• The following example shows the output of the show interfaces terse command when
you (as the master administrator) issue the command from the context of the main
router:
user@host> show interfaces terse at-0/0/0
Interface Admin Link Proto Local Remote
at-0/0/0 up up
at-0/0/0.0 up up ccc
at-0/0/0.32767 up up
The physical interface name at-0/0/0 is reported, followed by all requested information
(in the case of the show interfaces terse command, the Admin and Link states) about
the physical interface.
The logical interface name at-0/0/0.0 is reported, followed by all requested information.
The output also displays all requested information about the special, system-generated
logical interface at-0/0/0.32767, which the Junos OS uses for handling traffic that is
not part of the interface. In the case of the ATM interface at-0/0/0, which is configured
for cell-relay promiscuous virtual path identifier (VPI) mode, the system-generated
logical interface at-0/0/0.32767 is used to track statistics associated with
system-generated traffic, such as Operation, Administration, and Management (OAM)
F4 cell flows.
NOTE: The show interfaces extensive command output displays the
individual channel statistics associated with the special .32767 logical
interface, but only when the command is issued from the context of the
main router.
• The following example shows how you can place yourself into the context of logical
system ls1:
user@host> set cli logical-system ls1
Logical system: ls1
user@host:lst1>
• The following example shows the output of the show interfaces terse operational
command when you (as the master administrator) issue it from the context of logical
system ls1 or when it is issued by a logical system administrator for the logical system
ls1:
user@host:ls1> show interfaces terse at-0/0/0
Interface Admin Link Proto Local Remote
at-0/0/0
at-0/0/0.0 up up ccc
The physical interface name at-0/0/0 is reported, but any additional details about the
physical interface (in the case of the show interfaces terse command, the Admin and
