This chapter describes how to troubleshoot the installation of the Cisco ASR 1000 Series Fixed Ethernet Line Card on the Cisco ASR 1000 Series Aggregation Services Routers. This chapter contains the following sections:

Troubleshooting Installation Issues

This section provides troubleshooting information pertaining to the installation of the Cisco ASR 1000 Series Fixed Ethernet Line Card. Possible problems, observations and comments, and solutions are indicated for the following troubleshooting symptoms:

  • Cisco ASR 1000 Series Fixed Ethernet Line Card transitions repeatedly from on to off
  • Cisco ASR 1000 Series Fixed Ethernet Line Card is deactivated

 

Cisco ASR 1000 Series Fixed Ethernet Line Card Transitions Repeatedly From On to Off
Possible Problem
Observations and Comments
Solutions

Cisco ASR 1000 Series Fixed Ethernet Line Card is booting up, which is a normal operation.

Cisco ASR 1000 Series Fixed Ethernet Line Card STATUS LED alternates between green, amber, or off.

Wait for 150 seconds until the boot process completes and the STATUS LED stays on.

Cisco ASR 1000 Series Fixed Ethernet Line Card does not go beyond the bootup stage.

Cisco ASR 1000 Series Fixed Ethernet Line Card STATUS LED transitions continue and alternate between green, amber, or off.

Follow the recommended action for the displayed error message.

Cisco ASR 1000 Series Fixed Ethernet Line Card is not up to date.

During the Cisco ASR 1000 Series Fixed Ethernet Line Card initialization, the need to update the field-programmable gate array (FPGA) is automatically detected.

Follow the system prompts to update the FPGA image.

If the Cisco ASR 1000 Series Fixed Ethernet Line Card is cycling because of a field-programmable device (FPD) problem, the most likely cause is an FPD failure or that the FPD package file is not present.

 

Cisco ASR 1000 Series Fixed Ethernet Line Card is Deactivated
Possible Problem
Observations and Comments
Solutions

Cisco ASR 1000 Series Fixed Ethernet Line Card is not fully seated in the chassis slot.

Output of the show diag slot command.

STATUS LED is off.

Follow this procedure:

1. Remove the Cisco ASR 1000 Series Fixed Ethernet Line Card from the slot.

2. Inspect the Cisco ASR 1000 Series Fixed Ethernet Line Card. Verify that there are no bent pins or parts and that there is nothing that could prevent a good connection.

3. Insert the Cisco ASR 1000 Series Fixed Ethernet Line Card into the chassis slot.

Cisco ASR 1000 Series Fixed Ethernet Line Card is not at the minimum hardware-programmable revision level.

Error message indicating that the Cisco ASR 1000 Series Fixed Ethernet Line Card is not at the minimum FPGA revision level.

Output of the show hw-module subslot fpd command.

Output of the show diag slot command.

STATUS LED is off.

Follow the FPD upgrade process to update the FPGA.

Table 5-1 Troubleshooting Line Card States

Problem
Observation

Various problems with the line card states.
  • The LED on the line card front panel is green, indicating that the that line card is up and running with Cisco IOS.
  • The show platform command shows the status of line card slot as ok.
  • The show hw-module subslot x/y oir [ internal ] command indicates that the SPA operation status is ok.
  • The show running-config command shows interfaces for the line card.
  • The show ip interface brief command shows the configured interfaces for the line card if they are ready for configuration.

Using debug Commands

The debug hw-module subslot command is intended for use by Cisco Systems technical support personnel.

Caution Because debugging output is assigned high priority in the CPU process, it can render the system unusable. For this reason, use debug commands only to troubleshoot specific problems or during troubleshooting sessions with Cisco technical support staff. Moreover, it is best to use debug commands during periods of lower network traffic and fewer users. Debugging during these periods decreases the likelihood that increased debug command processing overhead will affect system use.

For information about the other debug commands supported on the Cisco ASR 1000 Series Aggregated Services Router error messages, including messages related to the Cisco ASR 1000 Series Fixed Ethernet Line Card, refer to the following documents:

  • Cisco IOS Release 12.2 SR Command References
  • Cisco ASR 1000 Series Fixed Ethernet Line Card Software Configuration Guide

Packing a Cisco ASR 1000 Series Fixed Ethernet Line Card for Shipment

This section provides step-by-step instructions for packing a Cisco ASR 1000 Series Fixed Ethernet Line Card for shipment. Before beginning this procedure, you should have the following original Cisco Systems packaging materials:

  • Static shielding bag
  • Smaller inner carton
  • Larger exterior carton
  • Two-foam packing cushions
Caution The Cisco Systems original packaging is to be used for the shipment of all Cisco ASR 1000 native line cards. Failure to use Cisco Systems packaging properly may result in damage or loss of product.
Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could electrocute yourself.

Note The following instructions assume that the Cisco ASR 1000 Series Fixed Ethernet Line Card has been removed from the router according to the procedures specified in this guide.

To pack a Cisco ASR 1000 Series Fixed Ethernet Line Card for shipment, perform the following steps:

Step 1 Insert the Cisco ASR 1000 Series Fixed Ethernet Line Card into the static shielding bag.

Step 2 Insert the bagged Cisco ASR 1000 Series Fixed Ethernet Line Card into the smaller inner carton. Ensure that you position the Cisco ASR 1000 Series Fixed Ethernet Line Card such that the bottom motherboard lip is held by the packaging cutout.

Step 3 Close the smaller inner carton and tape the sides closed.

Step 4 Place the sealed smaller inner carton containing the Cisco ASR 1000 Series Fixed Ethernet Line Card into the two-foam packing cushions (they only fit one way).

Step 5 Place the sealed smaller inner carton and packing cushions into the larger exterior carton, and seal the larger exterior carton with tape for shipment.

 

Troubleshooting Performance and Scalability

Each Cisco ASR 1000-ESP200 uses 4 third generation Cisco QFPs (QFP-3rd-Gen) Application Specific Integrated Circuits (ASICs) to achieve maximum performance. Each QFP-3rd-Gen ASIC is mapped with the Cisco ASR 1000 Fixed Ethernet Line Cards. Through this mapping, the Cisco ASR 1000-ESP200 can perform all baseline packet routing operations such as Quality of Service (QoS) classification and IP multicasting. They can also perform Network Address Translation (NAT) tasks.

The Cisco ASR 1000 Fixed Ethernet Line Card supports 48K VLAN configuration with QOS. When configuring 48K VLAN with QOS, ensure that you distribute the VLAN in a way that no single QFP-3rd-Gen is configured with more than 32K VLAN. For optimal performance, it is recommended to insert the the Cisco ASR 1000 Fixed Ethernet Line Card in central slots, that is, slot 2 or 3 in the Cisco ASR 1013 Router.

Figure 5-1 displays the Cisco ASR 1000 Fixed Ethernet Line Cards of the Cisco ASR 1013 Router and their mappings to the QFP-3rd-Gen ASICs.
