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:
Description: 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.
Execute the show configuration groups command to see whether the LCC groups are listed in the existing configuration.

If an LCC group is missing, then configure the group in configuration mode and perform the other required configurations.

SFC Configuration Not Synchronized with LCC Configuration
Problem:
Description: 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.
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]";
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:
Description: 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).
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.

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:
Description: 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.
To view alarms, execute the show chassis alarms command.
