How to collect logs of a CE series switch

Log information is save in four types of log files including the diag.log, log.log, diagnose.log (one-click logs), (memory logs) files.

To analyze software issues, collect log information in the diag.log, log.log, diagnose.log (one-click logs are the most important) files.

To analyze hardware issues, collect log information in the diag.log, log.log, (memory logs, which are the most important logs) files, and other related command lines.

Collect log information using either of the following methods:

1. Collect diagnostic logs in one click.


[~HUAWEI] diagnose

[~HUAWEI-diagnose] display diagnostic-information >> diagnose.log


1. Executing the command takes about 5 minutes. Please wait.

2. The diagnose.log file is exported to the root directory of the active MPU.

< HUAWEI >cd flash:

<~HUAWEI >dir

3. Collect log information in the diag.log, log.log, and files.


[~HUAWEI] diagnose

[~HUAWEI-diagnose] collect diagnostic information
[~HUAWEI-diagnose] return
<HUAWEI >save logfile

<HUAWEI > cd logfile:

<HUAWEI >dir


You can run the mput * command to collect all logs.

[ftp]mput *
