Problem:
Description: You have collected logs on your device and need to send them to Juniper Networks Technical Support. This topic shows you how to compress the logs into a single file for each Routing Engine to more conveniently send the logs.
Solution
You can compress all the log files in the /var/log directories of the master and backup (if
present) Routing Engines into a single tgz file for each Routing Engine, which enables you to send the logs
to JTAC in a convenient package. You can use either the CLI or the
command shell to perform these tasks; because of its ease of use,
only the CLI version is shown here.
- Access the device through the management IP address or
console, typically on the master Routing Engine, RE0.
user@host> - Archive and compress all the log files on RE0 and put
them in
/var/tmp.user@host> file archive compress source /var/log/* destination /var/tmp/re0.tgz/usr/bin/tar: Removing leading `/' from member names - Confirm that the compressed archive file has been created.
user@host> file list /var/tmpcontent_copy zoom_out_mapbaseline-config.conf gres-tp idp_license_info install jinstall-12.2-20120328.0-domestic-signed.tgz krt_gencfg_filter.txt preinstall_boot_loader.conf re0.tgz rtsdb sec-download vi.recover
On devices with a single Routing Engine, skip to Step 10.
- Log in to the backup Routing Engine, RE1, and access the
CLI.Note
1 is appended to the hostname in the prompt to signify that you are on RE1.
user@host> request routing-engine login backup% clicontent_copy zoom_out_mapuser@host11>
- Archive and compress all the log files on RE1 and put
them in
/var/tmp.user@host1> file archive compress source /var/log/* destination /var/tmp/re1.tgz/usr/bin/tar: Removing leading `/' from member names - Confirm that the compressed archive file has been created.
user@host1> file list /var/tmpcontent_copy zoom_out_mapbaseline-config.conf gres-tp idp_license_info install jinstall-12.2-20120328.0-domestic-signed.tgz krt_gencfg_filter.txt preinstall_boot_loader.conf re1.tgz rtsdb sec-download vi.recover %
- Exit the remote login to the backup Routing Engine to
return to the master Routing Engine. Note that the previously appended 1 is removed from the hostname in the prompt to signify
that you are back on RE0.
user@host1> exitcontent_copy zoom_out_maprlogin: connection closed user@host1>
- Copy the compressed archive file from RE1 to RE0.
user@host> file copy re1:/var/tmp/re1.tgz /var/tmp - Confirm the presence of the copied file.
user@host> file list /var/tmpcontent_copy zoom_out_mapbaseline-config.conf gres-tp idp_license_info install jinstall-12.2-20120328.0-domestic-signed.tgz krt_gencfg_filter.txt preinstall_boot_loader.conf re0.tgz re1.tgz rtsdb sec-download vi.recover %
- Copy the files directly from the master Routing Engine to any local host using FTP, SCP, JWEB, or (on some devices) a mounted USB.
