Troubleshooting: LCC in Amnesiac Mode

In a routing matrix with a TX Matrix Plus router and 3D SIBs, one or more LCCs are in amnesiac mode. LCCs can be in amnesiac mode because of the following reasons:

LCC Groups lcc number-re0 and lcc number-re1 Not Configured

Problem

In a routing matrix with a TX Matrix Plus router (or the switch-fabric chassis (SFC)) and 3D SIBs, one or more LCCs are in amnesiac mode.

Cause

The LCC groups lcc number-re0 and lcc number-re1 are not configured at the [edit groups] hierarchy level.

Solution

Check whether the LCC groups are listed in the existing configuration.

  1. Execute the show configuration groups command to see whether the LCC groups are listed in the existing configuration.
    user@host> show configuration groups ?
    Possible completions:
  <[Enter]>            Execute this command
  <group_name>         Group name
  global               Group name
  lcc0-re0             Group name
  lcc0-re1             Group name
  lcc2-re0             Group name
  lcc2-re1             Group name
  lcc3-re0             Group name
  lcc3-re1             Group name
  lcc4-re0             Group name
  lcc4-re1             Group name
  lcc5-re0             Group name
  lcc5-re1             Group name
  lcc6-re0             Group name
  lcc6-re1             Group name
  lcc7-re0             Group name
  lcc7-re1             Group name
  maximum-MTU          Group name
  mtu                  Group name
  re0                  Group name
  re1                  Group name
  |                    Pipe through a command
  2. If an LCC group is missing, then configure the group in configuration mode and perform the other required configurations.
    [edit]user@host# set groups lcc7-re1
  3. Commit the configuration.
    [edit]user@host# commit
  4. Exit configuration mode.
    [edit]user@host# exit

SFC Configuration Not Synchronized with LCC Configuration

Problem

In a routing matrix with a TX Matrix Plus router and 3D SIBs, one or more LCCs are in amnesiac mode.

Cause

If the SFC configuration is not synchronized with the LCC configuration, then the LCCs can be in amnesiac mode.

Solution

Check whether the SFC and LCC configurations are synchronized.

  1. To check whether the configurations are synchronized between the SFC and the LCCs, execute the show configuration version command on both the SFC and the LCCs. If the commit time is the same in both the output, then the configurations are synchronized.

    Output on SFC

    user@host> show configuration version
    ## Last commit: 2013-02-19 10:03:37 PST by userid
version "13.1I20130125_0953_xxx [xxx]";

    Output on LCC

    user@host> show configuration version
    ## Last commit: 2013-02-19 10:03:37 PST by userid
version "13.2I20130218_1838_xxx [xxx]";
  2. If the commit time in the output of the LCCs is different from that in the output of the SFC, then log in to the SFC Routing Engine in configuration mode and execute the commit synchronize statement to synchronize the configuration on the SFC and the LCCs.

Incompatibity Between LCC Routing Engine or Control Board and the TX Matrix Plus Router (SFC)

Problem

In a routing matrix with a TX Matrix Plus router and 3D SIBs, one or more LCCs are in amnesiac mode.

Cause

LCC Routing Engines or Control Boards (CBs) are not compatible with the SFC.

Solution

Check whether the LCC Routing Engines or Control Boards are compatible with the TX Matrix Plus router (SFC).

  1. To verify the compatibility between an LCC Routing Engine or Control Board and the TX Matrix Plus router, execute the show chassis hardware command on the LCC Routing Engine.
    user@host> show chassis hardware

  2. When upgrading a T640 LCC to a T1600 LCC or T4000 LCC, you might observe an error and the values for the following output parameters might differ from the sample shown above:
    • Routing Engine 0
    • Routing Engine 1
    • CB 0
    • CB 1

    If the values differ, then refer to the T1600 Router Upgrade Guide or T4000 Router Upgrade Guide to rectify the error.

Unsupported Hardware or Hardware Fault Alarms

Problem

In a routing matrix with a TX Matrix Plus router and 3D SIBs, one or more LCCs are in amnesiac mode.

Cause

If there are any unsupported hardware or there is a hardware fault in the routing matrix, then the LCCs can be in amnesiac mode.

Solution

Check whether the output lists any unsupported hardware or hardware fault alarms.

  1. To view alarms, execute the show chassis alarms command.
