ACI: Collecting a local techsupport from an APIC or Switch

[rsua]

 Introduction

There are certain situations in where an On-Demand Techsupport is not able to be performed.  In such cases, a local techsupport can be collected instead for either the APIC or an ACI switch.  This document outlines this process.

 Important Notes

• An On-Demand Techsupport is almost always preferred than a local techsupport as it provides a more complete picture
• Follow this link for a guide on collecting an On-Demand Techsupport

 Techsupport Local Scenarios

• APIC is not fully-fit
• ACI switch is not yet discovered by by the APIC
• ACI switch has lost communication with the APIC
• Internal process malfunction preventing On-Demand Techsupport operation (rare)

 APIC Techsupport Local Collection

1. Open an SSH session with the APIC using an admin credentials
   • If unable to login using admin credentials, use the username "rescue-user". The password should be the same as the "admin" local user.
2. Run the command bash -c "techsupport local"

   Using username "admin".

   apic1# bash -c "techsupport local"
   This command is being deprecated on APIC controller, please use NXOS-style equivalent command

3. Download the local techsupport
   
   • Option A: Download the techsupport file using SCP
     • WinSCP or pscp.exe (Windows Users)
     • Native SCP client (MAC Users)
   • Option B: Download the techsupport file using HTTPS
     1. Open a browser such as Chrome/Firefox
     2. Navigate to: https://[aci.apic.ip.addr]/files/[apic#]/techsupport/[ts_filename]
        • Ex: https://172.16.176.120/files/1/techsupport/local_apic1_2018-05-29T08-17.tgz
     3. Login using an admin credentials
     4. If prompted, click "Save File" on browser download prompt.

ACI Switch Techsupport Local Collection

1. Open an SSH session with the ACI switch using an admin credentials
   • If switch is not yet discovered by the APIC, use the username "admin"
2. Run the command "techsupport local"

3. Download the local techsupport

• Option A: Download the techsupport file from the ACI switch using SCP
  • WinSCP or pscp.exe (Windows Users)
  • Native SCP client (MAC Users)
• Option B: Download the techsupport file using HTTPS via the APIC
  
  1. Login to an APIC CLI (note which APIC is used for step#4)
  2. Transfer the techsupport file from the ACI switch to the APIC using the following command:
     • scp  [node-name]:/data/techsupport/[ts_filename]  /data/techsupport
       • Ex: apic1#  scp  fab5-leaf1:/data/techsupport/local_fab5-leaf1_2018-05-29T08-16.tgz   /data/techsupport
  3. Open a browser such as Chrome/Firefox
  4. Navigate to: https://[aci.apic.ip.addr]/files/[apic#]/techsupport/[ts_filename]
     • Ex: https://172.16.176.120/files/1/techsupport/local_fab5-leaf1_2018-05-29T08-16.tgz

Thank you for the response.

There is one slight error in your procedure. The scp command needs to be run on an APIC CLI.  This step is transferring the image from the switch to the APIC. SCP commands needs to be initiated on the APIC CLI when transferring between an APIC and a Switch.

Also, keep in mind of the general syntax of scp.

scp [from_location] [to_location]

In the example on the document:

apic1# scp fab5-leaf1:/data/techsupport/local_fab5-leaf1_2018-05-29T08-16.tgz /data/techsupport
