Collecting diagnostic log messages 

Collecting diagnostic log messages on a standalone centralized device 

# Save diagnostic log messages from the diagnostic log file buffer to a diagnostic log file. 

By default, the diagnostic log file is saved in the 

diagfile

 directory of the storage medium on the 

device. 

<Sysname> diagnostic-logfile save 

The contents in the diagnostic log file buffer have been saved to the file 

cfa0:/diagfile/diagfile18.log 

# Identify the diagnostic log file on the device. 

<Sysname> dir cfa0:/diagfile/ 

Directory of cfa0:/diagfile

Collecting diagnostic log messages on an IRF fabric that contains centralized devices 

1. 

Save diagnostic log messages from the diagnostic log file buffer to a diagnostic log file.  
By default, the diagnostic log file is saved in the 

diagfile

 directory of the storage medium on the 

master device. 

<Sysname> diagnostic-logfile save 

The contents in the diagnostic log file buffer have been saved to the file 

cfa0:/diagfile/diagfile18.log 

2. 

Identify the log file on each member device: 
# Display the log file on the master device. 

<Sysname> dir cfa0:/diagfile/ 

Directory of cfa0:/diagfile

Collecting diagnostic log messages on a standalone distributed device or on an IRF fabric 
that contains distributed devices 

1. 

Save diagnostic log messages from the diagnostic log file buffer to a diagnostic log file. 
By default, the diagnostic log file is saved in the 

diagfile

 directory of the storage medium on the 

active MPU (in standalone mode) or global active MPU (in IRF mode). 

<Sysname> diagnostic-logfile save 

The contents in the diagnostic log file buffer have been saved to the file 

cfa0:/diagfile/diagfile18.log 

2.
