Troubleshooting: Offline LCCs in a Routing Matrix with a TX Matrix Plus Router

The LCCs connected to a TX Matrix Plus router with 3D SIBs can be offline because of the following reasons:

Faulty Connection Between LCC Control Plane and the CIP

Problem

In a routing matrix, the LCCs connected to a TX Matrix Plus router with 3D SIBs are offline.

Cause

The connection between the LCC control planes and the Connector Interface Panels (CIPs) is faulty, which results in offline LCCs.

Solution

Check whether the connection between the LCCs’ control planes and the CIPs is all right.

To check the connection between the LCCs’ control planes and the CIPs, execute the show chassis cip command.

user@host> show chassis cip

sfc0-cip0    
Eswitch Port Type Connected-to     Link  Speed       Duplex Auto-Neg
0       5    XE   SFC0             Down  0           Full   Off

1       6    GE   LCC3             Down  0           Half   On   
1       8    GE   LCC4             Up    1000Mbps    Full   On   
1       10   GE   LCC5             Down  0           Half   On   
1       12   GE   LCC6             Down  0           Half   On   
1       14   GE   LCC7             Up    1000Mbps    Full   On   
1       16   GE   GE17             Down  0           Half   On   
1       17   GE   GE16             Down  0           Half   On

If the output displays that the LCC Ethernet cable is not connected, then check the cable connection between the LCC CB SFC 0 slot and SFC CIP LCC number. If the cable is not connected, then connect the cable. If the cables are connected, then check the link LEDs. If the link LEDs are not glowing, then replace the Ethernet cable.

LCCs Configured in Single-Chassis Mode

Problem

In a routing matrix, the LCCs connected to a TX Matrix Plus router with 3D SIBs are offline.

Cause

The LCCs might be offline if they are configured in single-chassis mode.

Solution

Check the LCC Control Board (LCC-CB) switch setting.

Check whether the switch on the LCC-CB is set to M (multichassis mode). If the switch is set to S (single-chassis mode), then change the switch setting to M.
Note: You must set the switch on both the Control Boards (CB-0 and CB-1) to M.
After changing the switch setting, reboot the LCC.
To set the LCC mode for the LCCs, refer to lcc-mode.
Note: After you set the lcc-mode, there will be a few seconds’ delay before the LCC state changes to online.

LCC Mode Set to empty

Problem

In a routing matrix, the LCCs connected to a TX Matrix Plus router with 3D SIBs are offline.

Cause

When the value of lcc-mode for an LCC is set to empty, that LCC is in offline state.

Solution

Check whether the LCC mode is configured as empty.

To verify the LCC mode, execute the show chassis lcc-mode command.

user@host> show chassis lcc-mode

Slot         LCC-mode
 0           T4000           
 1           EMPTY           
 2           T1600           
 3           T1600           
 4           EMPTY           
 5           EMPTY           
 6           T1600           
 7           T1600

To set the LCC mode for the LCCs that display the mode as EMPTY in the output with an appropriate value (T1600 or T4000), see lcc-mode.

LCC Configured Offline

Problem

In a routing matrix, the LCCs connected to a TX Matrix Plus router with 3D SIBs are offline.

Cause

An LCC appears offline when its state is configured as offline.

Solution

Check the state of the LCC.

To view the state, execute the show chassis lccs command.

user@host> show chassis lccs

Slot  State               Uptime
 0    Online             1 hour, 8 minutes, 24 seconds
 1    Empty           
 2    Online             1 hour, 8 minutes, 24 seconds
 3    Empty           
 4    Online             1 hour, 8 minutes, 26 seconds
 5    Empty           
 6    Empty           
 7    Online             1 hour, 8 minutes, 24 seconds

If the state of the LCC is offline, then log in to the LCC in configuration mode and set the state to online-expected. For more information, see online-expected.

LCC Routing Engine or CB Incompatible with the TX Matrix Plus SFC

Problem

In a routing matrix, the LCCs connected to a TX Matrix Plus router with 3D SIBs are offline.

Cause

The LCC Routing Engine or Control Board (CB) is not compatible with the TX Matrix Plus switch-fabric chassis (SFC).

Solution

Check whether the LCC Routing Engine or Control Board is compatible with the TX Matrix Plus router (SFC).

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

When upgrading a T640 LCC to a T1600 LCC or a T4000 LCC, you might have an error and the values for the following output parameter might differ from the sample shown above:
- Routing Engine 0
- Routing Engine 1
- CB 0
- CB 1
If the values differ, then to rectify the error, refer to the T1600 Router Upgrade Guide or the T4000 Router Upgrade Guide.

Unsupported Hardware or Hardware Fault Alarms

Problem

In a routing matrix, the LCCs connected to a TX Matrix Plus router with 3D SIBs are offline.

Cause

If there are any unsupported hardware or there is a hardware fault, then the LCC can go offline.

Solution

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

To view alarms, execute the show chassis alarms command.
