Collecting Subscriber Access Logs Before Contacting Juniper Technical Support

Problem

When you experience a subscriber access problem in your network, we recommend that you collect certain logs before you contact Juniper Technical Support. This topic shows you the most useful logs for a variety of network implementations. In addition to the relevant log information, you must also collect standard troubleshooting information and send it to Juniper Technical Support in your request for assistance.

Solution

To collect standard troubleshooting information:

• Redirect the command output to a file.
  user@host> request support information | save rsi-1

To configure logging to assist Juniper Technical Support:

1. Review the following blocks of statements to determine which apply to your configuration.
2. Copy the relevant statements into a text file and modify the log filenames as you wish.
3. Copy the statements from the text file and paste them into the CLI on your router to configure logging.
4. Commit the logging configuration to begin collecting information.

Note: The maximum file size for DHCP local server and DHCP relay log files is 1 GB. The maximum number of log files for DHCP local-server and DHCP relay is 1000.

Best Practice: Enable these logs only to collect information when troubleshooting specific problems. Enabling these logs during normal operations can result in reduced system performance.
