Syntax (TX Matrix Plus Router with 3D SIBs)

Release Information

Command introduced in Junos OS Release 13.1.

Description

Display optical link connectivity and its current status. Display the status of all the optical links on online SIBs along with the state of optical-link, high-speed link status and mapped FPCs. Show the cable connectivity based on mode of operation of line-card chassis (LCC) and flag the problems with cable connectivity, if any.

Options

detail(TX Matrix Plus routers with 3D SIBs only) (Optional) Display detailed output for optical link connectivity and current status of all the optical links. Also, highlight the FPC slots that are impacted in case of an error on a particular optical link.
lcc number(Optional) Display information for the LCC that is connected to the TX Matrix Plus router. Replace number with the following values depending on the LCC configuration:
  • From 0 through 7 on T1600 routers connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

  • 0, 2, 4, or 6 on T4000 routers connected to TX Matrix Plus router with 3D SIBs in a routing matrix.

Output Fields

Table 1 lists the output fields for the show chassis fabric optical-links command. Output fields are listed in the approximate order in which they appear.

Field Name

Field Description

Lcc optical link

Line Card chassis links are shown as LCCxx_SIByy_CXPzz, where xx is LCC number, yy is the LCC SIB slot ID, and zz is the optics number within that LCC SIB.

Link

The status of the optical link.

  • -----<?>----- Transceiver is not inserted in the SIB or not recognized.

  • -----(U)----- The connected transceiver is not supported.

  • -----(F)----- The connected transceiver is faulty or it has exceeded the operating limits.

  • -----< >----> The transceiver is inserted, but the cable is not connected. Loss of Light (LOL) is observed in the optics.

  • -----///----> The transceiver is not connected to the correct port. The link status indicates where it is wrongly connected.

  • -----(O)----> Indicates a bad or dirty cable or an issue with transceiver. Some channels show error.

  • -----(E)----> The cable is connected properly but high-speed link errors are present on this link.

  • -----(L)----) A loopback transceiver is inserted.

  • -----X----> Error due to high-speed links links being down.

  • ------------> The cable is connected but optical link is disabled.

  • ------------> The cable is connected properly with the requisite power settings. High-speed links on the port are up and running.

Sc optical link

Switch-fabric chassis links are shown as SFCa_F13bb_LCCcc_CXPdd, where a is the SFC chassis 0, bb is F13 SIB slot, cc is the LCC this cable is connected to, and dd is the optics number within that F13 SIB.

State

Link status:

  • Up—Link is online and fully functional.

  • Connected—The cable is connected but optical link is disabled.

  • Link Down—High speed links are down in the system.

  • Loopback—A loopback transceiver is inserted in the system.

  • Link Error—The cable is properly connected but high speed link error exists in the system.

  • Optical Error—Indicates a bad cable.

  • Mis connected—The transceiver is not connected to correct port.

  • Module Absent—The transceiver is not inserted in the SIB or the transceiver is not recognized.

  • Not Connected—The transceiver is inserted but cable is not connected to the system.

  • Faulty Module—The connected transceiver is faulty or it has exceeded the operating limits.
