Issue/Introduction

For a pair of interfaces in the DX Netops Portal, we see one interface has the ip of the other interface.

Environment

Release : 22.2.x

Resolution

If you see this issue pleas open a case with support with the following data:

1)Verify the DA has the correct IP addresses for the interfaces in question:

a) Get the DA localid of the interfaces in question bis steps 1-4 of the KB:

https://knowledge.broadcom.com/external/article?articleId=33163

b) Use that to get the Data Aggregator  rest for the ports:

http://<da>:8581/rest/ports/<dalocalid>

Adjust the port/protocol as needed.

2) Collect a CA Remote Engineer from the DX Netops Portal:

https://techdocs.broadcom.com/content/broadcom/techdocs/us/en/ca-enterprise-software/it-operations-management/performance-management/21-2/troubleshooting/unable-to-resolve-issue.html

3) Show the mismatch via a screenshot.

4) Please provide a walk of the device using sapwalk2:

On CAPM 3.6 or later, sapwalk is already installed on each Data Collector at:

/opt/IMDataCollector/scripts/sapwalk2

Note that your exact path may vary if you did not install the Data Collector in the default location.

Here is some example syntax:

Note: a full walk should start at 1.3.6, or use a targeted OID if requested for troubleshooting.

sapwalk2 -i <ip> -v v2c -s 1.3.6. -c <community> -o device_mib.walk
