Controlling the Scope of a Command

The JUNOS CLI operational commands include options that you can use to identify specific components on a device running JUNOS software. For example:

  1. Type the show interfaces command to display information about all interfaces on the router. 
    user@host> show interfaces 
Physical interface: so-0/0/0, Enabled, Physical link is Up
  Interface index: 128, SNMP ifIndex: 23
  Link-level type: PPP, MTU: 4474, Clocking: Internal, SONET mode, Speed: OC3,
  Loopback: None, FCS: 16, Payload scrambler: Enabled
  Device flags   : Present Running
  Interface flags: Point-To-Point SNMP-Traps Internal: 0x4000
  Link flags     : Keepalives
  Keepalive settings: Interval 10 seconds, Up-count 1, Down-count 3
  Keepalive: Input: 13861 (00:00:05 ago), Output: 13891 (00:00:01 ago)
  LCP state: Opened
  NCP state: inet: Opened, inet6: Not-configured, iso: Opened, mpls: Not-configured
  CHAP state: Closed
  PAP state: Closed
  CoS queues     : 4 supported, 4 maximum usable queues
  Last flapped   : 2008-06-02 17:16:14 PDT (1d 14:21 ago)
  Input rate     : 40 bps (0 pps)
  Output rate    : 48 bps (0 pps)

---(more)---
  2. To display information about a specific interface, type that interface as a command option: 
    user@host> show interfaces fe-0/1/3   
Physical interface: fe-0/1/3, Enabled, Physical link is Up
  Interface index: 135, SNMP ifIndex: 30
  Link-level type: Ethernet, MTU: 1514, Speed: 100mbps, MAC-REWRITE Error: None,
  Loopback: Disabled, Source filtering: Disabled, Flow control: Enabled
  Device flags   : Present Running
  Interface flags: SNMP-Traps Internal: 0x4000
  Link flags     : None
  CoS queues     : 4 supported, 4 maximum usable queues
  Current address: 00:05:85:8f:c8:22, Hardware address: 00:05:85:8f:c8:22
  Last flapped   : 2008-06-02 17:16:15 PDT (1d 14:28 ago)
  Input rate     : 0 bps (0 pps)
  Output rate    : 0 bps (0 pps)
  Active alarms  : None
  Active defects : None

Operational Mode Commands on a TX Matrix Platform

When you issue operational mode commands on the TX Matrix platform, CLI command options allow you to restrict the command output to show only a component of the routing matrix rather than the routing matrix as a whole.

These are the options shown in the CLI:

If you specify none of these options, then the command applies by default to the whole routing matrix: the TX Matrix platform and all connected T640 routing nodes.

Examples of Routing Matrix Command Options

The following output samples, using the show version command, demonstrate some different options for viewing information about the routing matrix.


user@host> show version ? 
Possible completions:
  <[Enter]>            Execute this command
  all-lcc              Show software version on all LCC chassis
  brief                Display brief output
  detail               Display detailed output
  lcc                  Show software version on specific LCC (0..3)
  scc                  Show software version on the SCC
  |                    Pipe through a command
Sample Output: No Routing Matrix Options Specified
