Controlling the Scope of a Command

CLI operational commands include options you can use to identify specific components on the router. 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: 260

   Link-level type: PPP, MTU: 4474, Clocking: Internal, SONET mode, Speed: OC3, Loopback: None, FCS: 16,

   Payload scrambler: Enabled

   Device flags: Present Running Up

   Interface flags: Hardware-Down Point-To-Point SNMP-Traps Internal: 0x4000

   Link flags: Keepalives

   CoS queues: 4 supported, 4 maximum usable queues

   Last flapped: 2006-02-02 09:26:25 PST (2w0d 06:20 ago)

   Input rate: 0 bps (0 pps)

   Output rate: 0 bps (0 pps)

   SONET alarms: LOL, LOS

   SONET defects: LOL, LOF, LOS, SEF, AIS-L, AIS-P

   Physical interface: so-0/0/1, Enabled, Physical link is Up

   Interface index: 129, SNMP ifIndex: 271

   Link-level type: PPP, MTU: 4474, Clocking: Internal, SONET mode, Speed: OC3, Loopback: None, FCS: 16,

   Payload scrambler: Enabled

   ---(more)---

2. To display information about a specific interface, type that interface as a command option:

   user@host> show interfaces fe-1/1/1

   Physical interface: fe-1/1/1, Enabled, Physical link is Up

   Interface index: 141, SNMP ifIndex: 33

   Link-level type: Ethernet, MTU: 1514, Speed: 100mbps, Loopback: Disabled, Source filtering: Disabled,

   Flow control: Enabled

   Device flags: Present Running Up

   Interface flags: Hardware-Down SNMP-Traps Internal: 0x4000

   Link flags: None

   CoS queues: 4 supported, 4 maximum usable queues

   Current address: 00:90:69:d0:f8:9e, Hardware address: 00:90:69:d0:f8:9e

   Last flapped: 2006-02-02 09:26:25 PST (2w0d 06:25 ago)

   Input rate: 0 bps (0 pps)

   Output rate: 0 bps (0 pps)

   Active alarms: LINK

   Active defects: LINK

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:

• scc—The TX Matrix platform.
• lcc number—A specific T640 routing node.
• all-lcc—All T640 routing nodes.

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.

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
