Description

This KB article describes a generic data collection Plan of Action (PoA) that covers packet drop and layer 2 debugging scenarios. All command lines have been consolidated into a single shell script that can be executed to collect the necessary data , along with the RSI and var logs, for Juniper JTAC and engineering further investigate the issue root cause

 

Important Notes:

• Use this script only as directed by Juniper Networks Technical Assistance Center (JTAC) or engineering teams.

• Always review the script and commands to ensure compatibility with your network setup and to prevent unintended changes.

• Juniper Networks assumes no responsibility for issues arising from the use of this script without proper validation or in environments not explicitly supported.

 

For additional assistance, please contact Juniper Networks JTAC.

Solution

 

 

Data collection script : 

 

#!/bin/bash

 

 

 

# Create folder if it doesn't exist

 

output_folder="/var/tmp/dc"

 

mkdir -p "$output_folder"

 

 

 

# Get current date and time

 

current_date=$(date +%Y-%m-%d)

 

current_time=$(date +%H:%M:%S)

 

 

 

# Function to prepend date and time as the first line in a file

 

prepend_date_time() {

 

  echo "Date: $current_date" >> "$1"

 

  echo "Time: $current_time" >> "$1"

 

  echo >> "$1"

 

}

 

 

 

# Execute the commands and redirect the output to individual files

Please note:

  • Make sure to save the script in a file with the .sh extension (e.g., script.sh), and then you can execute it using the following command: sh script.sh
  • This script will run each shell/PFE commands and redirect the output to separate files with the current date and time prepended. The files will be saved in the /var/tmp/dc directory. Please achieve the files with a fresh copy of RSI and var logs, and upload to new JTAC case
  • This script contains a few commands that can be only supported on the latest JUNOS software version
