Troubleshooting Interfaces

This chapter describes techniques that you can use to troubleshoot interfaces. It includes the following sections:

•Verifying and Troubleshooting Configured Interfaces

•Verifying and Troubleshooting Pluggable Optical Interfaces

•Troubleshooting Common Issues with Bundle Interfaces

Verifying and Troubleshooting Configured Interfaces

To troubleshoot the configured interfaces on Cisco IOS XR software, perform the following procedure.

SUMMARY STEPS

1. show interfaces type instance

2. show controllers interface-type interface-instance stats

3. show netio idb interface-type interface-instance

4. show controllers plim asic statistics interface type instance
or
show hw-module subslot address counters mac index
or
show hw-module subslot counters framer

5. Contact Cisco Technical Support if the problem is not resolved.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

show interfaces type instance

Example:

RP/0/RP0/CPU0:router# show interfaces gigabitEthernet 0/0/0/0

Displays statistics for all interfaces configured on the specified node. Check for interface errors.

Step 2 

show controllers interface-type interface-instance stats

Example:

RP/0/RP0/CPU0:router# show controllers gigabitEthernet 0/0/0/0 stats

Displays interface controller status and configuration statistics for the specified node. Check for input drops.

If input drops are found, contact Cisco Technical Support. For Cisco Technical Support contact information, see the "Obtaining Documentation and Submitting a Service Request" section in the Preface.

Step 3 

show netio idb interface-type interface-instance

Example:

RP/0/RP0/CPU0:router# show netio idb gigabitEthernet 0/0/0/0

Displays network input and output information for a specified node.

Check the software counters for the interface. Under Chains and Protocol chains in the output check if any drops occurred at a particular point in the Encap or Decap of the packet. The drops are displayed in the column on the right, showing drop packets and bytes for each step in the chain.

Step 4 

show controllers plim asic statistics interface type instance

or

show hw-module subslot address counters mac index

or

show hw-module subslot counters framer

Example:

RP/0/RP0/CPU0:router# show controllers plim asic statistics interface tenGigE 1/3/0/0

or

RP/0/RP0/CPU0:router# show hw-module subslot 0/0/0 counters mac 0

or

RP/0/RP0/CPU0:router# show hw-module subslot counters framer

•Use the show controllers plim command for fixed PLIMs. Check for interface drops on fixed physical layer interface modules (PLIMs).

•Use the show hw-module subslot address counters mac command and show hw-module subslot counters framer command for shared port adapters (SPAs). Check for interface drops on SPAs.

Check the application-specific integrated circuit (ASIC) counters for drop counters or error counters incrementing for the interface.

Step 5 

Contact Cisco Technical Support.

For Cisco Technical Support contact information, see the "Obtaining Documentation and Submitting a Service Request" section in the Preface.

Verifying and Troubleshooting Pluggable Optical Interfaces

Troubleshooting the pluggable optical interfaces includes verifying that you have an optical card installed, enabled, and functioning properly. To troubleshoot the configured pluggable optical interfaces, perform the following procedure.

SUMMARY STEPS

1. show hw-module subslot address brief pluggable-optics

2. show hw-module subslot address status pluggable-optics

3. show hw-module subslot address errors pluggable-optics

4. show hw-module subslot address registers pluggable-optics

5. Contact Cisco Technical Support if the problem is not resolved.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

show hw-module subslot address brief pluggable-optics

Example:

RP/0/RP0/CPU0:router# show hw-module subslot 0/6/4 brief pluggable-optics

Displays a brief summary of the pluggable optics status for all nodes, including optics type, vendor, and state. Check that the state is enabled for the node that you are troubleshooting.

Step 2 

show hw-module subslot address status pluggable-optics

Example:

RP/0/RP0/CPU0:router# show hw-module subslot 0/6/4 status pluggable-optics

Displays the status of the pluggable optics for the specified node, including faults and environmental data. Check that the state and the transceiver are enabled. Check for any warnings or alarms.

Step 3 

show hw-module subslot address errors pluggable-optics

Example:

RP/0/RP0/CPU0:router# show hw-module subslot 0/6/4 errors pluggable-optics

Displays any errors that are present on the node. Note if there are any errors.

Verify that Phased Initialization displays Phase Reached: 4. Verify that Socket Verification displays "passed" for both Compatibility and Security.

Step 5 

Contact Cisco Technical Support.

For Cisco Technical Support contact information, see the "Obtaining Documentation and Submitting a Service Request" section in the Preface.

The following example shows typical outputs for these commands on systems.

Troubleshooting Common Issues with Bundle Interfaces

Bundle interfaces utilize features and services provided by different components. To troubleshoot the common issues with bundle interface components on Cisco IOS XR software, perform the following procedure.

SUMMARY STEPS

1. show tech-support bundles file filename

2. show bundle bunde-name

3. show iir interfaces name bundle-name

4. show iir interfaces name bundle-name location location-id

5. show pfi-ifh database bundle-name location location-id

6. show cef adajacency bundle-name hardware egress detail location location-id

7. show cef adajacency bundle-name hardware ingress remote detail location location-id

8. Contact Cisco Technical Support if the problem is not resolved.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

show tech-support bundles file filename

Example:

RP/0/RP0/CPU0:router# show tech-support bundles file filename

Collects the output from bundle in both normal and admin modes and stores it in a file. It is important to do this as soon as possible after observing a problem because the traces with valuable information for debugging may wrap and be lost. It is strongly recommended that the command output be sent directly to file, rather than screen scraped, to avoid loss/corruption of part of the logs.

Step 2 

show bundle bunde-name

Example:

RP/0/RP0/CPU0:router# sh bundle bundle-ether 202

Make sure that the member links are in Distributing (4) state.

Step 3 

show iir interfaces name bundle-name

Example:

RP/0/RP0/CPU0:router# show iir interfaces name bundle-ether 202

Ensure that the member links are in ACTIVE state.

Step 4 

show iir interfaces name bundle-name location location-id

Example:

RP/0/RP0/CPU0:router# show iir interfaces name bundle-ether 202 location 0/RP0/CPU0

Make sure the IIR database of Bundle Interface Information is in sync.

Step 5 

show pfi-ifh database bundle-name location location-id

Example:

RP/0/RP0/CPU0:router# show pfi-ifh database bundle-ether 205 location 0/1/CPU0

Make sure that the PFI-IFH database of bundle interface info is in sync.

Step 6 

show cef adajacency bundle-name hardware egress detail location location-id

Example:

RP/0/RP0/CPU0:router# show cef adjacency bundle-name hardware egress detail location 0/RP0/CPU0

RP/0/RP0/CPU0:router# show cef adjacency bundle-name hardware ingress remote detail location 0/RP0/CPU0

Make sure that the TLU entries are allocated and bundle adjacency info is properly programmed

Step 7
